Water pumps "Caliber": an overview of the range and use cases

The principle of the device and basic repair

The device of the Malysh pump is based on the properties of electromagnetic oscillations, which are transmitted to the float valve, forcing the membrane to oscillate and thereby push water through. With the help of an automatic device, the operation of the engine is controlled, which is turned off when overheated, as well as after pumping the entire volume of water.

Pump models may differ in the location of the suction holes. or after pumping all the water.It is preferable to purchase a Malysh pump with an upper intake, since in this equipment the electric motor is located below, and therefore it cools better. The suction hole, located on top, does not capture silt deposits and other impurities from the bottom of the water intake. Such equipment can work without problems in the immersed state for a long time at a water level below the suction holes.

A similar situation will not be tolerated by models with a lower water intake. Therefore, their work must be monitored, not leaving the switched-on equipment unattended for a long time. When buying, it is advisable to choose models with thermal protection that prevents the engine from overheating. It is possible to repair the Baby pump with your own hands in case of replacing leaky valves and other minor breakdowns. It is necessary to resort to the help of specialists if the product has not expired the warranty period, as well as when replacing a burned-out engine.

Submersible pump Kid with top water intake and thermal protection

Properly selected power, careful operation and compliance with the recommendations given by the manufacturer allow you to prevent breakdown of the purchased pumping equipment.

Buyers who are attentive to the operation of the pump are satisfied with its work and give the most positive feedback. You can choose the right pump model with the help of specialists who will help you install and connect it.

Pump "Caliber" in the water supply at home

In the absence of a central water supply system, artesian wells are used in household plots, as well as shallow wells and wells. Mine wells can be shallow - from 3-4 meters and deep - from 10 to 15 meters.The laying depth of an ordinary well is 20-40 meters, an artesian well is more than 40 meters, depending on the occurrence of the aquifer.

To lift water from the depth of these alternative sources, a submersible borehole pump "Caliber" is installed.

Types of alternative water sources in the garden

Two operating principles are used in downhole pumping equipment - vibration and centrifugal. Centrifugal pumps are more powerful and productive, therefore they are used for constant water supply at home, vibration pumps are used for irrigation and small household needs.

Lifting water from a depth of up to 25 m - "Caliber" NBC

Pumps of this type are used to supply water from wells, reservoirs, wells to the water supply system of the house. The pump housing is made of plastic, stainless steel or cast iron, which is displayed in the pump markings in the form of the letters P, N or H. The Caliber surface pump can be equipped with a submersible ejector - an additional element for water intake, which allows to increase the suction height. The cost of pumps of this type varies from 1000 to 3500 rubles.

Technical characteristics of pumps "Caliber" NBC:

• Productivity 30 — 80 l/min
• Power consumption up to 900 W
• Maximum suction lift 7 to 9 m
• Maximum lifting height from 30 to 60 m

Submersible borehole models "Caliber" NPCS

Technical characteristics of pumps "Caliber" NPCS:

• • Productivity from 1.2 to 1.5 m3/h
  • Power consumption from 370 W to 1.1 kW
  • Maximum lifting height from 50 to 100m
  • Maximum immersion depth 5 m

Maximum suction particle size 1 mm

Submersible borehole pumps "Caliber" have the shape of a cylinder of small diameter and can be installed in any well

Using the Caliber pump for irrigation - HBT models

The vibration pump "Caliber" can be used in watering, irrigation, irrigation systems for lifting water from wells and boreholes, sometimes for automatic water supply. The main disadvantages of such pumps are: noise in operation, limitation in the depth of water intake and low efficiency. Vibratory pumps can use the top or bottom way to draw water.

With the upper intake, the pump overheats less, since its entire body is immersed in water. Pumps of this type are equipped with built-in thermal protection, which turns off the unit in case of overheating or lack of water.

The marking of this pump includes its power and the length of the power cord. The price of vibration submersible pumps is in the range of 800-2500 rubles.

Vibration pumps of this manufacturer are economical in operation and are perfect for watering a personal plot.

Technical characteristics of pumps "Caliber" NVT:

• Pump diameter from 78 to 98 mm
• Productivity from 7.5 to 40 l/min
• Maximum lifting height from 40 to 70 m
• Power cord length 10 to 25 m
• Power consumption from 200 W to 700 W

Drainage works with pump "Caliber" SPC

Spring floods, prolonged rains, an emergency - all these factors can lead to flooding of the basement of the house and the accumulation of water in the garden. In this case, you can not do without a drainage pump. The drainage pump "Caliber" with the NPC marking is used for pumping contaminated water from basements, cellars, ditches, wells, artificial reservoirs, pools. Some modifications of the pump are equipped with a float with a switch, which is activated in case of a drop in the water level. This function protects the pump from overheating and failure.

Drainage submersible pumps "Caliber" are indispensable for pumping contaminated water with inclusions of various fractions

Technical characteristics of drainage models:

• Productivity from 8 to 18 m3/hour
• Power consumption from 0.25 to 1.35 kW
• Maximum lifting height from 7 to 12 m
• Maximum suction particle size from 5 mm to 35 mm

There are modifications of the Kalibr pumps for sewage drainage, which can pump liquids without limiting the maximum diameter of the particles sucked in. The marking of the drainage pump displays its power, the diameter of the particles sucked in and the material from which the housing is made. The cost of pumps "Caliber" of this type ranges from 900 to 7000 rubles.

Selection Options

Well pumps are easy to distinguish even by their appearance. They are an elongated cylinder made of stainless steel or plastic. Naturally, stainless steel models are more expensive - the steel must be of high quality (usually food grade AISI304). Pumps in a plastic case are much cheaper. Although they are made of a special impact-resistant plastic, they must be handled with care - it still does not tolerate shock loads very well. All other parameters will have to be selected.

Brief technical characteristics of the pump for the well

Water flow and pump performance

In order for the water in the house or in the country to be with sufficient pressure, equipment is needed that can deliver the required volume of liquid. This parameter is called pump performance, measured in liters or milliliters (grams) per unit of time:

• ml/s - milliliters per second;
• l / min - liters per minute;
• l / h or cubic / h (m³ / h) - liters or cubic meters per hour (one cubic meter is equal to 1000 liters).

Borehole pumps can lift from 20 liters/min to 200 liters/min. The more productive the unit, the greater the power consumption and the higher the price. Therefore, we choose this parameter with a reasonable margin.

One of the key parameters for selecting a well pump is performance

The required amount of water is calculated by two methods. The first takes into account the number of people living and the total expense. If four people live in the house, then the water consumption per day will be at the rate of 800 liters (200 l / person). If there is not only water supply from the well, but also irrigation, then some more moisture must be added. We divide the total amount by 12 (not by 24 hours, because at night we use water supply to a minimum). We get how much we will spend on average per hour. Dividing it by 60, we get the required pump performance.

For example, for a family of four and watering a small garden, it takes 1,500 liters per day. Divide by 12, we get 125 liters / hour. In a minute it will be 2.08 l / min. If you often have guests, you may need a little more water, so we can increase the consumption by about 20%. Then you will need to look for a pump with a capacity of about 2.2-2.3 liters per minute.

Lifting height (pressure)

When choosing a pump for a well, you will inevitably study the technical specifications. There are parameters such as lifting height and immersion depth. Lifting height - also called pressure - is a calculated value. It takes into account the depth from which the pump will pump water, the height to which it must be raised in the house, the length of the horizontal section and the resistance of the pipes. Calculated according to the formula:

The formula for calculating the pump head

An example of calculating the required pressure. Let it be necessary to raise water from a depth (pump installation site) of 35 meters. The horizontal section is 25 meters, which equates to 2.5 meters of elevation. The house is two-story, the highest point is a shower on the second floor at a height of 4.5 m. Now we consider: 35 m + 2.5 m + 4.5 m = 42 m. We multiply this figure by the correction factor: 42 * 1.1 5 = 48.3 m. That is, the minimum pressure or lifting height is 50 meters.

If there is a hydraulic accumulator in the water supply system of the house, it is not the distance to the highest point that is taken into account, but its resistance. It depends on the pressure in the tank. One atmosphere is equal to 10 meters of pressure. That is, if the pressure in the GA is 2 atm, when calculating, instead of the height of the house, substitute 20 m.

Immersion depth

Another important parameter in the technical specifications is the immersion depth. This is the amount with which the pump can pump out water. It varies from 8-10 m for very low-power models to 200 m and more. That is, when choosing a pump for a well, you need to look at both characteristics at once.

For different wells, the depth of immersion is different

How to determine how deep to lower the pump? This figure should be in the passport for the well. It depends on the total depth of the well, its size (diameter) and flow rate (the rate at which water arrives). In general, the recommendations are as follows: the pump should be at least 15-20 meters below the water surface, but even lower is better. When the pump is turned on, the liquid level drops by 3-8 meters. The amount remaining above it is pumped out. If the pump is very productive, it pumps quickly, it must be lowered lower, otherwise it will often turn off due to lack of water.

Well diameter

An important role in the selection of equipment is played by the diameter of the well. Most domestic well pumps have sizes from 70 mm to 102 mm. In general, this parameter is usually measured in inches. If so, then the easiest way to find three and four inch specimens. The rest are made to order.

The well pump must fit in the casing

Advantages and disadvantages of Caliber brand units

Of course, the cost of Caliber pumps is the strongest side of this product.

However, in addition to the low price, Caliber has other advantages, namely:

Surface pump Caliber

• Acceptable power consumption - the most powerful pump spends no more than 1.3 kW, and the most successful (in terms of efficiency) instances consume only 0.2 kW (like two light bulbs).
• Good stability when working with heavily polluted media. Pumps pump over not only clean water, but also sand suspension or lime mortar.
• Wide functionality. In the assortment of the trade mark caliber there are units for irrigation installations, and pumps for drainage or cleaning (swinging) of wells.

However, all users who use the Caliber pump in the water supply at home note a number of disadvantages of such products, namely:

• Unstable product quality. The Caliber brand belongs to domestic businessmen, but the production facilities of this brand are located in China.
• Not the longest period of operation. The filling of pumps "Caliber" is assembled from inexpensive components. And cheap components simply cannot work on a par with expensive and high-quality parts.

But, we repeat - the low price, and the cheapest pump of this brand costs only a couple of hundred rubles, justifies all the shortcomings described above.

Features of the submersible device

According to the depth of lifting, the units of the brand "Caliber" are divided into deep and ordinary, according to the type of working chamber, vibration and centrifugal are distinguished, according to the layout - submersible and surface. Caliber models are marked with letters.

Water pump Caliber sold online and in specialized stores

This marking indicates the material from which the pump housing is made:

• H - ordinary steel;
• H - cast iron steel;
• P - plastic case.

One of the manufacturers of pumping equipment is the Russian company Kalibr. Such equipment is attractive to the buyer due to its low budget cost and excellent functionality.

Focusing on the demand of buyers, manufacturers produce equipment of various categories - from inexpensive, which is used for watering the garden, to more significant, required for the implementation of a full-fledged water supply system.

Caliber products can be classified, like any unit for a water supply system, according to the following criteria:

• The scheme of location in the well;
• Type of working chamber;
• lifting depth.

Vibrating household appliances - NBC are very popular. They will be useful to those who have a source of water in their suburban area, used for household needs and watering the garden or vegetable garden from time to time.

Running in

An obligatory guarantee of a long service life of a minitractor is the correct running-in. At this time, all parts are run in, and all components of the unit are lubricated.

It is very important to follow the engine and transmission oil change schedule during the break-in period.

• An oil check is recommended before every work shift.
• It is desirable to use special oil SAE10W30, which may vary depending on the season of operation.
• The oil is changed after 50 hours of operation, and it is desirable to operate the tractor without attachments.
• The next replacement is made after 100 and 200 hours. Further - according to the schedule specified in the operating instructions. During break-in, all fasteners are checked and, if necessary, tightened.
• The power take-off shaft also needs to be run in. You should start at low speeds, gradually increasing them and alternating for 5-10 minutes. After running in, drain the oil and replace with new.

SPC - drainage equipment

SPC is a series of drainage devices operating on the centrifugal principle. Brand pumps cope even with heavily polluted water (suspensions). The device can be placed in a liquid or kept on a surface.

For pumping contaminated water, more powerful devices are needed, and the Caliber company offers the largest series - drainage, consisting of 15 models: 7 of them are enclosed in a plastic case, 4 in steel, 4 more in cast iron.

The last group is fecal pumps capable of moving a very contaminated liquid with large (up to 15 mm) foreign inclusions - pieces of clay, debris, sand.

Easy to maintain, compact devices are easy to carry from place to place and use at your discretion for the following needs:

• equipping the water supply system at home;
• lowering the level of groundwater;
• water intake from natural reservoirs - rivers and lakes;
• maintenance of decorative ponds and pools;
• application in irrigation and watering systems;
• drainage of cellars, reservoirs;
• elimination of the consequences of accidents, floods.

Plastic pumps are lighter, more convenient for transportation, but stainless steel counterparts are more productive.

Metal units easily cope with pumping hot water and cleaning the sewer system. But there are also limitations: NPTs cannot be used to move fuel, sea water and liquids with corrosion inclusions.

Device and specifications

The pumping chamber of the unit is capable of passing through itself large particles of dirt up to 3.5 centimeters in size. Equally successfully, such a pump pumps out both drainage water from flooded basements and the contents of fecal effluents and sewer pits.

In its design, a submersible drainage pump resembles a centrifugal one - water moves under the action of the impeller. However, for operation, it must be completely lowered into the water, and the liquid level is controlled by a special device - a float.

As an example, an overview of the Caliber NPC-400 model:

• It is necessary to completely lower it into the water, and the liquid level is controlled by a special device - a float.
• The lower part of the housing is designed in such a way that it allows the intake of contaminated water (with particles up to 35 mm), the weight of the pump is 4.5 kg.
• Purpose of the pump Caliber NPC-400: submersible centrifugal pump Caliber NPC-400 is designed for pumping clean or slightly polluted water, the temperature of which does not exceed +40°C
• Power and performance of the submersible pump: power - 400 W, productivity - 150 l / min. (about 9 cubic meters per hour), immersion depth - 8 m, head - 6 m.
• Automatic float switch with fixation: the pump body is made of durable sealed plastic, and the automatic "float" has a special place for fastening - so the device is more convenient to store and carry.
• Design features and weight: the pump body is made of durable sealed plastic, and the automatic "float" has a special place for fastening - so the device is more convenient to store and carry.

Pros and cons of units of this type

Advantages:

• affordable price;
• reliability;
• ease of operation and maintenance;
• high performance.

Flaws:

• cannot be used at great depths;
• noise of work;
• high power consumption.

Features of vortex type devices

Vortex pumps work with a vortex wheel that generates a lot of force. The principle is based on the twisting of water into a spiral (vortex). One of the main advantages is a powerful pressure. When compared with centrifugal, with the same weight and dimensions, the vortex pump is the most powerful. As a rule, the sizes of vortex units are smaller than centrifugal ones.

The downside of vortex pumps is their high sensitivity to granules (particles, impurities) in water. If a large amount is ingested and improperly used, the vortex pump can quickly fail.

Vortex models of pumps are used for irrigation in the garden and garden, installed in the water supply system of the house, cottage. The difference and undoubted advantage is the resistance to air ingress into the pipeline. Due to its compact size, it is used in many areas. There are several models of this type that are popular and in demand - Unipump 83861 (96432, 38873), submersible (Unipump 86107, 38803), Vortex NP-650 surface type.

What are consumers saying?

Consumers note the low price and low noise level of Caliber centrifugal pumps.

Other positive qualities of this pumping equipment include the fact that borehole pumps work well in water with a high limestone content.

The disadvantages of the units "Caliber" users attributed the following features:

• After about a year of operation, the Caliber pump may experience wear on internal components made of powdered metals, as well as corrosion of bolts and other external assembly elements.
• Such a part of the pump as a coupling is quite unreliable and can quickly fail.
• If any components of the Caliber unit break down, you will have to wait a long time for the components.
• Quite often, the Caliber water pump works intermittently, the relay is constantly activated, the continuous operation time is limited, so such a pump is hardly suitable for long-term irrigation.

Characteristics of the unit for the well

Submersible downhole devices are a stainless steel cylinder that is immersed to 5 m. Such a device has a small diameter, so it can be installed in any well. Such a pump pumps water on its own, and not with the help of an ejector or a pipe. Separately, it is necessary to purchase pressure pipes and fittings to connect it to the hydraulic tank. The power supply line is supplied with the unit and is a three-wire cable with a waterproof sheath.

Submersible devices can be used for the following needs:

• To equip the water supply system in the house;
• To lower the groundwater line;
• For water intake from rivers and lakes;
• For maintenance of ornamental ponds, pools;
• In irrigation systems, watering;
• When draining basements and reservoirs, large containers;
• To eliminate the consequences of accidents and floods.

Metal pumps are more efficient than plastic ones, they can easily handle both pumping water and cleaning sewers. However, they cannot be used to move sea water, combustible mixtures. By design, the submersible drainage mechanism is similar to the centrifugal one.Equipment "Caliber" for a well is distinguished by the fact that it is capable of transporting liquid from great depths without losing performance even in the presence of impurities up to 1 mm in size in the water, for example, coarse sand. The well pump is part of the water supply system, this mechanism works great from an AC induction motor drive. The line of such pumps - models with power from 250 to 1120 W, give a good performance of 1.2 m3 / h to 3.8 m3 / h.

Worn parts in the pump should be changed from time to time

Deep-well pumps of this line are distinguished by power up to 1.0 kW, head lifting height of liquid up to 100 m, average productivity on the soil surface reaches 1.3-1.6 m3/h, high service life, lightness and ease of maintenance. For comparison, the household surface pump NBTs-380 is a unit with a capacity of only 380 W, which is needed for pumping clean water from wells and open reservoirs, and watering the garden.
