How to choose a sewer pump: a complete classification and analysis of models

Selection rules

When choosing which fecal pump is better to buy, you need to pay attention to many parameters. The main features to choose from are:

Device type. All pumps are divided into outdoor and indoor. The former are in high demand, especially in the country, they are durable and unpretentious.The second models are placed near the toilet and sink, which allows for forced pumping of wastewater into septic tanks.

Installation methods. Based on the installation site of the equipment, there are submersible and surface devices. Surface mounted indoors, include several working parts, the feature is simple maintenance, but loud operation and fear of moisture. Submersible models are completely lowered into an aggressive environment, they serve for years and are characterized by high performance. All nodes are not subject to corrosion, the body is sealed, and inside there is a float mechanism that automates the switching on and off of the device.

Materials. Modern manufacturers use several basic materials in the manufacture of pumps. Often the body is made of plastic, stainless or cast iron. The disadvantage of the latter is the susceptibility to corrosion, and the steel itself is short-lived for an aggressive environment. The best stainless steel devices. Plastic is not afraid of an aggressive environment, but can easily be deformed from mechanical damage, but the more such material, the lower the cost of equipment.

Chopper. Such an addition will be very useful, since solid particles often enter the drains, and with the help of the cutting part they will be crushed. Models with 2-blade knives are best suited.

Technical specifications
The main attention should be paid to performance, the more it is, the faster the wastewater is pumped, but the current costs will be greater

For a private house, the optimal power will be devices of 500-1500 W
If it is important to supply wastewater over a long distance or height, then it will be necessary to select devices with a high jet pressure.In everyday life, there is often enough pressure up to 8 meters, but not less than 4-5.

Knowing the main selection parameters, you should consider several options for the units and determine for yourself which fecal pump is best for your home.

What are the features of a fecal pump

Many people wonder if conventional sewage pumps can be installed. Many experts will immediately say that only fecal pumps are capable of pumping liquids with a high concentration of impurities and solid deposits.

Features of the fecal pump are that even large impurities and solid deposits will not cause rapid wear of the structure. Do not assume that the filter element at the inlet of the drainage or other pump will solve the problem - in this case, the filter will clog extremely quickly, which will cause an increase in load and also increase the degree of wear of the structure.

A brief overview of popular Sololift models

There are a lot of popular and reputable manufacturers and brands on the market for such equipment. Let's take a look at some of the models.

Pumping unit Sololift WC1

This type of toilet pump is equipped with a grinding mechanism. Thanks to this, feces, toilet paper and other objects turn into a homogeneous mass, which is evacuated into the drain pipe and does not clog the drain. The device has protection of the electric motor against overheating: as soon as the temperature of the motor reaches a critical point, the device turns off. After cooling down, the unit restarts automatically. The sewage pump with a chopper has compact dimensions and is easily installed behind the toilet.

The volume of the tank of the device is 9 liters, weight - 7.3 kg.For normal operation of the drain system, it is recommended to mount the device at a distance of up to 150 mm from the toilet bowl. The installation is fixed on a horizontal surface with screws and dowels.

Expert opinion
Valery Drobakhin
Water supply and sewerage design engineer, ASP North-West LLC

“The model of the pumping station is not equipped with a chopper, so it cannot be used to connect to the toilet. It also prevents food waste from entering the sewer system, which can cause a breakdown of the unit.”

Sololift C-3 is used to remove large volumes of liquid. This pumping unit is able to remove wastewater, the temperature of which reaches 90°C.

Station model Sololift Grundfos C-3

How to choose and install a pump?

For private use, submersible devices are usually used, less often surface ones. They are cheap, easy to install and operate.Now we will analyze 3 options for installations for various cases.

1. It is necessary to connect the toilet and sink, but they are below the level of the main sewer. In this case, a forced pump is ideal. For example, Jemix STP-100. It is equipped with a fractionating knife, and it is easy to handle two consumers.
2. A similar situation, but a washing machine and a shower cubicle are added to the consumers. In this case, a more powerful pump will be required. Suitable apparatus CLEAN WG ESPA, designed for a toilet and 3 other elements.
3. All plumbing is located above the basement. It is necessary to organize a pressure system. For such conditions, submersible pumps with a built-in grinder are excellent. The Grundfos SEG device is capable of lifting water from a depth of 10 m, working with a capacity of 18 cubic meters. m/h

Before choosing a pump, you need to decide on the type of future mechanism.

Consider the instructions for connecting a forced sewage pump.

1. Place the device on the floor, behind the toilet.
2. Connect the toilet to the central outlet of the unit using the supplied corrugation.
3. Plastic pipes with a diameter of 40 mm, connect the rest of the consumers.
4. Connect the unit to the mains.

What are they for?

The need to install this equipment in an apartment can be caused by several factors, namely the redevelopment of simple city apartments. Sometimes, to arrange a comfortable space, it is necessary to move the bathroom and toilet to the center of the apartment.

Sometimes the kitchen needs to be moved from one room to another, so that the dishwasher and sink are next to the sewer riser.In this case, the pipeline will have to be broken, and this is fraught with the formation of blockages.

In addition, a new route will have to be laid for the pipe, which can run through the hallway or room. This is unacceptable. Successfully solve such problems allow sewer pumps for the apartment.

Overview of leading manufacturers

Leading manufacturers specializing in the production of pumping equipment, in an effort to improve the performance of the units, are constantly improving their products. Each brand has its own design features.

Products of the Italian brand Pedrollo

Pedrollo is the best Italian manufacturer, whose products are represented in more than 160 countries around the world. The equipment produced under this trademark meets the international quality standards UNI EN ISO 9001.

Pedrollo units are able to function smoothly even in heavily polluted environments, the inclusion diameter of which reaches 50 millimeters (+)

A feature of Pedrollo products is that both outdoor and submersible models are equipped with impellers that simultaneously act as grinders. This solution is convenient because it eliminates the need to purchase additional equipment.

The second feature of the units of this brand is the two-channel design of the impeller. This solution minimizes the risk of clogging the mechanism with fibrous inclusions, which often happens with conventional models when rotating elements are entangled.

Grundfos pumping equipment

The products of the Danish company, which is very popular with buyers, the name of which, when literally translated, means “spring” as a synonym for purity, is distinguished by the use of advanced water treatment technologies.

Grundfos fecal pumps stand out from pumping products by using when equipping the system thermal relay and installation impeller control mechanism

The regulating system of the impeller in addition to the installed thermal relay increases the working life of the unit and increases its safety during operation. The equipment of this brand is capable of servicing fecal sewage, the short-term temperature rises of which reach about + 35 ° С.

Many fans have found the Grundfos seg model, which does an excellent job with stagnant drains containing a lot of debris. The price of the product is 50 thousand rubles.

Professional units Calpeda

The Italian company is another major manufacturer on the world stage. It boasts a wide range of models and a huge production line.

For a long-term period of operation and pumping large volumes, the Calpeda GMG model is ideal, but you will have to pay about 100 thousand rubles for it

The series of fecal pumps of this brand is represented by four lines: "GMG" - with grinders, "GMV" - with a vortex impeller, "GMC" - with a single-channel wheel, "GMN" - with a multi-channel one.

Gileks - a product of domestic production

The leader in the domestic market of professional equipment is the trademark Dzhileks. The company's production was built on the experience of world holdings with the use of innovative technologies.

The "Fekalnik" series of pumps includes a wide range of pumps, characterized by small size, quiet operation and wide functionality.

Pumps of a domestic manufacturer can be used for pumping and transporting polluted waters, in which there is an increased content of silt and sand inclusions. The limiting size of fractions is 35 mm.

The Fekalnik 150/6 household model deserves special attention, the average price of which is 3 thousand rubles. The unit is not intended for professional purposes, but easily copes with pumping out sewage in a private house.

How should I choose a fecal pump?

The passport of the sewer pump for giving contains a lot of technical characteristics. And all of them must be considered when choosing this technique. The first indicator is the operating temperature of the pump, i.e. drain temperature.

Pumping equipment for sewage can be:

1. Designed to work only with cold and warm water up to +45°C.
2. Designed for pumping wastewater with temperatures up to +90°C.

To pump out water from the cellar and fecal sewage from a street septic tank, a pump of the first category is sufficient. But for uninterrupted functioning as part of a forced sewage system with a mass of plumbing in a country house, you will have to select a model from the second group.

Automation, chopper and body material

Constantly monitoring the status of the fecal pump and managing its operation manually means wasting your time. The cottage is always full of activities. Therefore, the technique should be immediately selected with a float and a thermal relay.

The first one will control the level of effluents in the pumped out pit, turning off / off the pump as necessary, and the second one will prevent the motor from overheating.

Some fecal pumps are able to handle solid waste and pebbles without a grinder, but only the presence of a cutting mechanism guarantees such a technique a long service life.

Structurally, the grinder is made in the form:

• two-bladed knife;
• impellers with a cutting edge;
• combined mechanism with several blades.

The impeller is the cheapest chopper option, but pumps with it have the lowest performance. A knife with a pair of blades located perpendicular to each other is more reliable and productive.

However, the most advanced is the combination of three cutting blades and a perforated disc. Passing through such a grinder, solid fecal fractions are converted into a homogeneous ground mass.

According to the material of the case, it is best to choose a pump for pumping sewage in the country from metal. Stainless steel and cast iron will last many times longer than plastic. This nuance is especially important for submersible equipment, which is constantly in dirty waters that are aggressive in composition.

Lift height, power and power supply

The higher the performance indicated in the passport, the faster the pump will pump drains. However, the more it will consume electricity. A cesspool in a country house is rarely made voluminous, so a low-power unit is often enough to work in a summer cottage. He will pump out the drains not in 5 minutes, but in 20, but there is nowhere to rush outside the city.

The best option for giving a pump in terms of power is 400–500 watts. This is a performance in the region of 140-160 l / min.Such performance characteristics will make it easy to cope with pumping sewage from a drain or cesspool, and getting rid of excess water in a country cellar.

The pressure figures show the maximum height to which the pumping equipment through the pressure pipe is able to lift liquid with feces. But when calculating this indicator, it is necessary to take into account not only the vertical section of the highway, but also the horizontal one.

In addition, one should take into account the atmospheric pressure, the material of manufacture and the cross section of the pipes, as well as the temperature of the effluents and the size of the impurities in them. In a simplified calculation of the required pressure, the footage of the horizontal section is divided by ten and added to the length of the vertical pipe section, and then all this increases by 20–25% - the resulting figure should be less than that indicated in the data sheet (+)

In a simplified calculation of the required pressure, the footage of the horizontal section is divided by ten and added to the length of the vertical pipe section, and then all this increases by 20–25% - the resulting figure should be less than that indicated in the data sheet (+)

Some models of sewer pumps are designed to be powered by a single-phase network, while others are powered by a three-phase one. The first group is cheaper. As a rule, it is recommended to choose just such a fecal pump for giving. It will cause less problems with connecting to the mains. And if necessary, it can be powered from a portable generator.

Main characteristics of sand noses

The sand pump is a single-stage, cantilevered equipment with an open impeller of one-way inlet.The pumps are of the centrifugal type and do an excellent job with both abrasive particles and sludge deposits. However, there are certain limitations of the physicochemical properties of the liquid. The indicators are:

1. Temperature range from +5 C to +60 C;
2. Density up to 1300 kg/m3;
3. The concentration of silt and abrasive inclusions is not more than 25%;
4. The maximum size of fractions is up to 10 mm;
5. Microhardness up to 9000 MPa.

The scope of the equipment is wide: metallurgy, mining, construction and domestic needs. The pump for pumping silt and sand is able to cope with the following list of tasks:

• cleaning and subsequent filling of trench structures;
• pumping out sludge residues, silt, clay, sand, household waste;
• cleaning the pond from pollution;
• pumping out water from caissons during the construction period;
• restoration and cleaning of coastal zones;
• removal of streams with marble dust;
• extraction of sand, silt from the bottom of wells, wells.

The equipment is ideal for pumping liquids in fire hazardous conditions.

Connecting to the system

You can connect the pumping mechanism to the drain system with your own hands, however, connecting to electricity will require certain skills.

for each model there is a detailed description of such a ratio

So, for example, with a pipeline height of 4 m, the horizontal cannot exceed 10 m, and with a height of 1 m, the length can reach 50 m

It is important to comply with this condition, since the quality of wastewater discharge depends on it.

The following installation steps:

1. A drain pipe from a siphon or toilet bowl is inserted into the receiver of the pumping unit.
2. The reverse side of the device is brought closer to the riser.
3. Connect the system to the power supply network, having previously installed a protective relay (RCD).

Mounting steps for sololifts of various types and manufacturers differ little from each other. You need to carefully read the instructions and follow their recommendations.

Overview of the best brands

The modern market opens wide horizons for the selection of fecal pumps equipped with grinders. Italian, German, Spanish and other equipment is offered to customers, and each manufacturer puts up an impressive range of models for sale.

Imported products, which are present in large quantities on the modern market. The main suppliers of fecal pumps are German, Italian, Spanish companies

grundfos. Among the best manufacturers, the first place in the ranking is the company. The Germans have succeeded in the development and production of pumps for various purposes. Not without German ideas in the production of fecal equipment with a grinder.

Their Grundfos Seg model, made for professional use, is well suited for ordinary private households. Despite the cast-iron body of the device, it is easy to transport from one place to another.

The electric motor of the device is endowed with a sensitive system of protection against overheating and short circuits. There is a regulator of speed of rotation of a rotor of the electric motor. With a maximum operating power of 0.9 kW, it gives a pressure of at least 15 meters. Dives to a depth of 10 meters.

The Grundfos brand is famous for producing a wide range of garden pumps.The line of submersible pumps presented to the buyer is dominated by models for pumping clean and dirty water.

Gilex. German equipment attracts the buyer with technology, but pushes it away with a high price. It was the affordable cost, combined with good quality, that brought Dzhileks Fekalnik to second place.

The development of Russian engineers also belongs to the category of professional equipment. The effectiveness of the action and quality indicators in the work were appreciated by many users of this equipment.

"Dzhileks Fekalnik" is made of stainless steel. It can be submerged to a depth of 8 meters. The power of the device is 0.4 kW, and the productivity is 160 l / min. A reliable hermetically sealed housing, equipped with a thermal protection system, also attracts simple maintenance.

Herz. The next best representative of liquid pumping devices is another German invention, this time from Herz. Model WRS25/11 is in high demand due to its reliability, durability and wear resistance. A feature of the model is the design for use in extreme conditions.

Fecal pumps of the German manufacturer Herz attract with excellent performance, practicality and a wide range that allows you to choose equipment for pumping any volume.

The development from Herz provides a capacity of up to 260 l / min., creates a pressure of up to 14 meters and can dive to a depth of 8 meters. The weight of the pump is 31 kg due to the cast iron body and steel working parts. The motor winding has insulation class "B".

Vortex. The well-deserved fourth position in the ranking of the best is occupied by the Whirlwind fecal pump. The FN-1500L model showed good results in operation.Efficient pumping and efficient shredding of large debris. Fully automatic control of the water level in the working chamber - switching on and off when the set parameters are reached.

Device for pumping faeces brand "Whirlwind". The pump equipped with a grinder is manufactured by a Russian company. The technique has received clear recognition from users. Demand for Whirlwinds exceeds supply

The pump is capable of lifting a column of liquid up to 18 meters. The productivity of the device reaches the value of 24 cubic meters / hour. Throughput on crushed particles - 15 mm. Maximum power - 1.5 kW. Material - a steel blade of a chopper knife and a cast-iron casing of the pump itself.

A fecal pump with a self-sharpening chopper from Italian manufacturers is designed for operation in extreme conditions. The design allows diving to a depth of 20 meters. During operation, a pressure of up to 40 meters is created. Productivity indicator - 16 cubic meters / hour.

A powerful device from an Italian manufacturer is the Calpeda GMG fecal pump with a grinder, which is endowed with a self-sharpening mechanism. Equipment, the service life of which depends only on the natural wear of parts

This is how the rating of the best pumping equipment from the group of fecal systems looks like. Of course, this list should be taken only conditionally. The range of pumping equipment is very large, and only five models are not able to show the situation in full. But in the case of choosing a pump for everyday life, it is quite logical to focus on the designated list.

Comparison of pumping equipment for hot and cold drains

If you plan to use a country shower without heating, then you can put a simple pressure or vacuum unit, while a model that is resistant to high temperatures is suitable for pumping hot drains. Equipment for pumping cold liquid waste has a temperature limit of up to 400 C.

Universal sewer pump

Some models equipped with knives are universal - they grind inclusions of a large fraction and can pump both cold and hot drains, but such equipment is expensive. Usually the unit is installed behind the toilet, with which it is connected by an adapter.

Advice! You can save a lot by installing separate installation for each plumbing unit: for a bathtub / shower stall and a washing machine, install a vacuum or other unit that can withstand high temperatures, and for a toilet bowl - a toilet pump for cold drains with a chopper.

Proper use and care of the pump

Any technique should be treated with care. Transfer sewer pumps are no exception in this matter. These devices also need to be repaired and efforts made to ensure that they function in proper condition.

Many devices today are automated, but human involvement in the operation is considered indispensable. Each sewer pump needs to be carefully inspected from time to time for all sorts of leaks.This applies even to new devices, which may not perform as advertised during the warranty period.

Preventive maintenance is required to prevent emergencies. When a pump fails, it must be repaired or replaced. Consequently, there may be interruptions in the water supply or problems with drainage. In this case, living conditions in a summer cottage can significantly worsen.

In the absence of appropriate skills and knowledge, it is undesirable to attempt to open sewer pumps on their own in order to carry out repairs. Without proper experience, it will be difficult to properly assemble the pump. An untrained user can only deal with the problem of leakage at the place where the pump is connected to the pipe without any problems. It is advisable to trust only qualified specialists to repair the pump itself.

It is advisable to flush the lubrication systems of the pumps with new oil. It is highly undesirable to use waste products for such purposes. The device must always be kept clean. Any contamination impairs performance. Some pumps have limits on continuous operation time. To determine the direction of rotation correctly, you need to find the arrow on the body.

If tapping is heard during operation of the device, the bearings, rotating parts or housing elements will have to be replaced. If difficulties arise with the supply of oil, you will have to blow out the dropper and fix the connecting fasteners more securely.

If the pump capacity decreases over time, some components will have to be replaced.If the pump housing overheats, flush the pump with lubricants and clean the piping.

Varieties of sewer pumps by installation method

For the arrangement of sewerage in a country house, devices of various installation methods can be used. It depends on the design features how exactly this or that sewage pump will be installed.

Be sure to take all this into account if you intend to do the installation yourself.

So, let's get acquainted with the classification of these pumps according to the method of their installation.

• External pumps for sewers. They are installed above sewer wells. We are talking about the so-called "dry" installation, in which only intake hoses are immersed in wastewater. By the way, it is for this reason that external models are not used for fecal matter.

Submersible pumps for sewerage. Characterized by the fact that they are completely immersed in drains

Installed at the bottom of the pit with the help of an angled outlet and special guides, it is important that the device sinks deeper than the mark recommended by the manufacturer, otherwise operational difficulties may arise. Such systems can be vertical (they are immersed to a maximum of 7 meters) and horizontal (up to 100 meters)

Be sure to take this into account when choosing a particular model. We also add that it is necessary to use only high-quality submersible pumps - the casing must be resistant to corrosion, as it will be in an aggressive environment

As a rule, such devices are used in private cottages in the arrangement of sewer systems.

Semi-submersible sewage pumps. They can dive into drains only 1-2 of their hull, as you can guess from the name. More specifically, only the pumping part of the model is submerged, while the engine remains at the top. For fixing, a special float is used. According to experts, such models should not be used for fecal effluents, since, alas, they do not have grinders.

Which manufacturer do you prefer?

In order for the consumer not to be confused in the assortment of sewage pumping pumps at home, you need to know the popular manufacturers of such products. And I want to start with a device equipped with vortex wheels made of polymer or cast iron materials. The modern market can offer many models of such devices, but Vortex brand products are considered the most popular.

Their main purpose is to pump out wastewater from human waste, which have solid inclusions no larger than 50 mm. They will perfectly cope with pumping liquids in which silt or fine sludge is present, as well as abrasive impurities.

Among the units equipped with a two-channel stainless steel working drive, the most popular are pumps manufactured by the Pedrollo brand. They are used to pump out septic tanks, cesspools or sewers. In addition, they are often installed in automated systems designed to divert sewer or drainage effluents.

Submersible Models

The device is initially created taking into account the factor that will be used with various aggressive substances. Therefore, in the manufacture of components and mechanisms, cast iron or stainless steel is used.

Before choosing such a fecal pump, you need to consider that during operation it must be at the bottom of the well. Equipping it with a special switch and an automation unit allows it to function autonomously.

Cutter Pump mounted like this:

• At the bottom of the well, a branch pipe is strengthened;
• Along the wall surface there are guides for its descent;
• A chain or a very strong cable is attached to the device;
• Lower the unit along the guides;
• On the pipe, it is fixed under the influence of its own weight.

When it becomes necessary to make repairs, it is easily removed using a cable along the guides. For summer residents, this equipment option is almost ideal. It features simple structure and easy operation.

Watch a video about submersible models:

When solving the problem of which fecal pump to choose for your septic tank, please note that a submersible machine with a power of 40 kW. It is capable of lifting up to 400 m³ of wastewater to a height of two dozen meters in one hour. The main purpose of this equipment is the pumping of wastewater with all kinds of impurities, both long-fiber and solid.

To be sure of the high-quality removal of large inclusions, it is better to install a fecal pump with a cutting mechanism installed on it
