Comparative review of the best manufacturers

Grundfos is rightfully considered the market leader. The Danish company is the oldest manufacturer of pumping equipment. The developments introduced by the technologists of the leading company were subsequently adopted by other manufacturers.

The equipment of this manufacturer is famous for its ability to easily cope without harm to itself with water of any degree of contamination, as well as high reliability.

The range of manufactured products is represented by pumps of all varieties and types. And all of them are united by one thing - the highest quality, confirmed by an effective manufacturer's warranty.

Another imported brand that has earned a positive reputation among buyers from all over the world is the Pedpollo brand.

Over 40 years of activity, the Italian company has grown into a powerful "heavyweight" in the pumping equipment market, becoming a worthy competitor to the world's leading manufacturer

“Pedrollo pumps work everywhere” is the main slogan of the world famous brand. And if you study the characteristics of the equipment it produces, then it is worth highlighting the versatility of its application. Pumps are capable of operating in contaminated water, aggressive environments and at high temperatures.

Among the pumping equipment of domestic production, the products manufactured under the following trademarks have proven themselves the most well:

• "Dzhileks" - pumping equipment of a domestic manufacturer is focused on the conditions of the Russian hinterland with its abundance of "difficult" soils and wetlands, as well as possible power outages.
• "Whirlwind" - pumps from this manufacturer are famous for their high power and low noise.The certified equipment produced by the company undergoes numerous performance and endurance tests.
• "Prorab" - powerful and unpretentious in maintenance pumps of this brand are produced on the basis of advanced technologies. This allows the company to keep the quality bar at a high level.

Among the brands of dirty water pumps, the brands "DAB", "Karcher" and "Belamos" have also proven themselves well. The equipment produced under these brands is famous for its optimal price-quality ratio.

When purchasing the right model, you have to prioritize: pay more and choose an unquestioned European brand, or purchase an inexpensive domestic product, but at the risk of receiving low-quality warranty support.

In order not to doubt your choice, we suggest that you familiarize yourself with the rating of drainage pumps.

Domestic sewer installations

Fecal pumps are also called small-sized pumping stations, which are designed to be built directly into the sewerage system inside a country house. Structurally and according to the principle of operation, such pumps resemble analogues from washing machines.

First, wastewater in such a household installation accumulates in a small tank, and as it fills up, it is pumped out by an internal submersible pump into the sewer pipe (+)

Similar models of fecal pumps belong to the premium plumbing segment and cost a lot. However, thanks to them, toilets, showers and washstands can be installed almost anywhere in a residential building. They calmly pump drains even through pipelines inclined upwards.

The design of this pumping station was originally based on the principle of self-cleaning.It is undemanding in terms of maintenance, it is enough to occasionally flush the tank from silt.

It also has a carbon filter and a check valve. The first excludes the appearance of sewer amber in the room, and the second does not allow the return of effluents from the sewer back to the storage. Fecal toilet pumps prevent blockages and provide forced drainage.

Quality drainage pumps at low prices

Drainage pumps are used to pump clean or dirty water. They are used for drainage of flooded premises, basements, trenches, pits, as well as for the intake of liquid from open reservoirs, wells and various reservoirs. These units will be useful for private use due to their compact size and low cost.

When pumping contaminated water, the particle size of the suspension should not exceed a few millimeters; it is not allowed to include fibrous fragments that can block the pump impeller and lead to its breakdown. Drainage pumps are equipped with float switches that protect them from running dry and allow them to operate in automatic mode, ensuring a low liquid level.

The price is from $ 110, efficiency and noiselessness are pluses, but a weak network drive is a minus of equipment.

A preliminary analysis of the needs, the design of the water intake source, determining the length of the flow and the functional features of the water supply will allow not only to choose a good quality device, but also to correctly determine exactly how many pumps will be needed to uninterruptedly supply water to a house, household or suburban area.

Installing a drain pump step by step instructions

First of all, it is necessary to correctly install a flat platform that can fix the pump in a vertical position. Thereafter:

a hose is attached to the outlet, and fixed with special clamps; when using a float device - put a check valve on the outgoing hose; in the case of a three-phase model, it is necessary to pay attention to the correct connection to the power supply, the blades must rotate clockwise; the pumping device is fastened with a special cable, which ensures the immobility of the fastening of the structure; responsibly approach the selection of a hose for pumping water, it must correspond to the throughput of the equipment

It is important to follow the operating instructions and safety precautions
If unexpected failures occur during operation, the pump must be turned off and raised to the surface to determine the cause of the malfunction. It is important to follow the operating instructions and safety precautions

Calculator for calculating the required pressure for a drainage pump

Automatic calculation of pump head.

Any pump has limitations on the depth from which it can pump fluid. Another important metric is productivity. It shows the volume of liquid that the unit is able to pump. The weakest devices have a capacity not exceeding 100 l / min. The choice for this parameter depends on the conditions in which the equipment is to operate.

If large volumes are pumped, the performance is chosen as large as possible. Inefficient equipment is enough to pump out the water that comes in little by little. The main thing is that less liquid is collected in the storage tank than the pump can pump out.

When calculating the required pressure, take into account:

• the difference in height between the water intake level and the highest point of the main;
• horizontal distance from the bottom of the intake hose to the end of the pipeline;
• diameter of pipes, hoses.

In the proposed calculator, you must specify all the parameters and get the result.

Design and principle of operation of the equipment

Initially, these devices were created for pumping water from basements flooded with water. Later, the scope of use of drainage pumps expanded. Modern models are designed for pumping lightly contaminated liquids from pits, wells, pools, pumping and cleaning wells.

In addition, they are used in production, included in the technological process. Most devices are capable of pumping liquids with impurities of about 10 mm in size.

Drainage pumps are specific equipment designed for a rather narrow range of work. It is not recommended to use it for other purposes.Despite the fact that drainers are used for cleaning shallow wells and shaft wells, they are not intended for permanent work in them.

The devices cannot work as a fecal pump either, although some "craftsmen" are trying to replace them.

Drainage pumps are designed for pumping and pumping clean or slightly contaminated liquids, can be used for draining small ponds, pumping and cleaning wells

Drainage equipment can only work with lightly contaminated liquids. The amount of solid impurities, depending on the type of apparatus, varies from 3 to 40 mm.

Whereas fecal pumps operate in aggressive liquids with a complete absence of solids. They are necessarily equipped with grinders, which, with the help of special blades, completely eliminate large contaminants.

If we consider the device device in the most general form, it consists of several elements:

• Electrical engine.
• Impeller located on the shaft. Responsible for the movement of fluid inside the device. Can be placed directly on the engine or at some distance from it.
• Pump unit. It is equipped with an intake pipe. The liquid enters the device through the holes in the nozzle. Their diameter determines the size of impurities that the device can handle.
• Sealed body. Inside it are all the working elements.
• Circuit breaker. Turns on and off depending on the liquid level. This prevents the equipment from flooding or its so-called "dry running".

Typical pump diagram:

The design of the drainage pump includes several basic elements, which are presented in the form of a diagram in the figure.

When the device is activated, an electric motor is started, which rotates the shaft with the impeller. A zone with rarefied air is formed around the moving blades, which reduces the pressure inside the chamber.

The liquid is drawn in through the orifices and passes into the device. Here, under the influence of centrifugal force, it is pushed to the outlet, from where it enters the pipe or outlet hose.

For normal operation of the pump, it is important that the amount of solid impurities inside the chamber does not exceed 10% of its volume. One more nuance

Standard drains are not intended for pumping hot liquids.

They can do this for a short time, as the engine of the device cools down, giving off heat to the pumped liquid. If you need to constantly pump hot water, you should choose a special model.

Having reviewed 16 pumps in the category of drainage and drainage-faecal, it is safe to say that there is plenty to choose from.

It is important that the pump is not bought at random: without taking into account the technical capabilities and operating conditions. Here the proverb will be in place: measure seven times, cut one

After all, even the best pump, under improperly selected operating conditions, can produce a minimum performance. We hope that our advice on choosing a pump and the models reviewed will make your choice easier.

Main types

Pumps for dirty water are divided according to the type of construction into 2 types:

Such models are installed above the tank. The devices are placed on a flat surface in a dry place. Pumps of this type have an inlet and outlet pipe and can operate automatically. To do this, a mechanism is attached to the toggle switch that reacts to the liquid level. When filling the cellar or depression in the area, the pump starts to automatically pump out water until the float mechanism is triggered, signaling the absence of liquid.

Pumps of this type operate in the same way as surface pumps, but are designed to work in deep wells or wells. Pumping is carried out without an inlet hose. In such models, a filter is installed that protects the pump from hard ground and sand. Such pumps cannot be used when pumping from reservoirs up to 20 meters deep. When compared with surface devices, you can highlight more power and no noise during operation. They do not require constant monitoring of the water level, as they turn off automatically.

Pumps are divided according to their purpose - domestic and industrial. Models of the first type are used for several purposes:

• pumping out water accumulated in the cellar or basement;
• removal of liquid from wells;

• watering the garden;
• removal of water from pools.

Low-power pumps of this type are capable of pumping up to 800 liters per minute.

It makes no sense to buy industrial pumps for pumping water on a personal plot, since they consume more energy and require the involvement of specialists for their maintenance. Such pumps are capable of lifting water to a height of up to 150 meters and pumping out water at a speed of 1500 liters per minute.
