Overview of the range of pumping equipment
When it comes to pumping equipment of this brand, first of all remember a small vibration pump, suitable for use in shallow wells. It is often purchased because of the low price and is not in a hurry to repair in case of a breakdown, because it is easy to buy a new one.
In fact, the name Caliber is carried by units for various purposes (well, borehole, drainage) and even pumping stations.
NBV - inexpensive equipment for wells
NBV - household vibration pumps will be useful to anyone who has a source of clean water at their summer cottage and uses it from time to time for all kinds of household needs or watering.
Small in size and weight equipment is easily installed in the well, it is also easy to get and store in any convenient place (the main thing is that the room should be dry and with a positive temperature).
A sample of the HBT line is a model with an upper water intake, with a diameter of 78 mm and a power of 210 W. Productivity of 12 l / min is enough to water the garden, flower beds or garden
The device of the vibrating pump “Caliber” practically does not differ from similar models of other brands. Inside the case there are several interconnected parts: a core with a magnetic coil, a vibrator (anchor), a rubber diaphragm, a check valve, a rod, a shock absorber.
The process of magnetization / demagnetization (with a frequency of about 100 times / sec) causes the movement of the diaphragm, which moves the fluid from the suction chamber to the discharge, and from there to the pipeline. The rapid movement of the rod creates a feeling of vibration, hence the name of the mechanism - vibration.
The models of pumps with a vibration principle of action, produced by manufacturers of the CIS countries, have a similar design
The NBV line is represented by seven models, which differ in terms of power (from 210 W to 300 W), performance (from 7 l / min to 12 l / min), lifting height (from 40 m to 70 m), and also a long cord (from 10 m to 40 m), weighing (from 2.3 kg to 5.5 kg) and dimensions.
In the configuration for the models there are a clamp and a nylon cable, but there is no hose, which must be purchased separately. When installing the mechanism in water, you must fasten the cable, electrical cord and hose together and hang them in a stable bundle so that the apparatus itself is at some distance from the bottom (at least half a meter).
NBC - models for home use
NBC - centrifugal household pumps are also represented by 7 models. Two models have the lowest power - 380 watts, the most powerful pump - 900 watts. Capacity - from 28 l / min to 55 l / min, but one model (NBC-0.75E) is equipped with an ejector, therefore it has an increased capacity of 80 l / min.
All pumps of the NBC series are made in steel or cast-iron cases, except for one model - NBC-600PK (PC - plastic case)
The lifting height of the surface pumps, as is known, does not exceed 9 m, however, the unit with the ejector and here surpasses its fellows, raising the liquid by 25 m.
In addition, it differs in that it is equipped with a pressure gauge and a check valve.
The NVTs-380 model is suitable not only for watering, but also home water supply devices. Like all centrifugal pumps, it can pump only clean or slightly polluted water (in this case, we recommend installing filters)
Consider the technical base of the pump NBTs-380 more closely.
A photo of
Caliber NBTs-380 refers to a surface self-priming pump with a centrifugal design
Pump power - 380 W, liquid lifting height - 25 m, productivity - 28 l / min
The depth of fluid intake is 9 m, the working pressure is 3 atmospheres. This is a great option for autonomous water supply cottages.
The advantages of the model are low weight (3.6 kg), reliable construction and durable material manufacturing

The advantages of the Caliber NBC-380 model
The device of the centrifugal unit is simple: a rod with an impeller, which blades accelerates the fluid entering the body, is placed in a robust housing, pushing it towards the exit with centrifugal force. There may be several wheels - such devices are called multistage.
The principle of operation of the centrifugal device NBTs: under the pressure of the water enters the working chamber, then the blades of the wheel is distributed around the periphery and moves in the direction of the outlet
Surface pumps are installed either near the well (in the caisson) or in the basement of a residential house. The depth of water intake is small (maximum 8-9 m), but it can be increased by connecting ejector. NBC can provide a family of 2-3 people with clean water.
SPC - Submersible Drainage Pumps
For pumping polluted water, more powerful machines are needed, and Caliber offers the largest series - drainage, consisting of 15 models: 7 of them are enclosed in a plastic case, 4 - in steel, another 4 - in cast iron.
The last group is fecal pumps, able to move a very polluted liquid with large (up to 15 mm) foreign inclusions - pieces of clay, garbage, sand.
The model NPC-1350NF differs from the rest of the drainage-fecal pumps in that it has an additional device - a shredder. The unit is capable of processing wastewaters of any type of pollution, the size of the particles being inhaled is indicated as “unlimited”
It should be noted that all the NPCs are declared by the manufacturer as universal, that is, they can move both clean and dirty liquid.
Convenient to maintain, compact devices are easy to carry from place to place and use at your discretion for the following needs:
- equipping the house water supply system;
- groundwater level reduction;
- water intake from natural reservoirs - rivers and lakes;
- maintenance of ornamental ponds and pools;
- application in irrigation and watering systems;
- drainage of basements, tanks;
- 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 limitations: the NPC cannot be used to move fuel, seawater and liquids with inclusions of corrosion.
The diagram shows the principle of operation of the float device: at normal water level, the device operates in the normal mode, at reduced - automatically turns off
According to its submersible device drainage pump reminds centrifugal - water moves under the action of the impeller. However, for its operation it is necessary to completely lower it into water, and the level of the liquid is controlled by a special device - a float.
As an example - a review of the model Caliber SPC-400.

Submersible centrifugal pump Caliber NPTs-400 is designed for pumping clean or slightly polluted water, the temperature of which does not exceed + 40 °
Power - 400 W, performance - 150 l / min. (about 9 cubic meters per hour), immersion depth - 8 m, head - 6 m
The pump body is made of durable hermetic plastic, and the automatic "float" has a special place for mounting - so the device is more convenient to store and carry
The lower part of the body is designed in such a way that allows you to take contaminated water (with particles up to 35 mm), the pump weight is 4.5 kg

SPCSS - equipment for wells
Downhole equipment is different in that it has the ability to lift fluid from a great depth without loss of performance. For example, centrifugal Caliber submersible pumps have a volume height from 40 m to 100 m, and the most powerful devices do not stop working if there is impurity in the water up to 1 mm in size.
The pump line is represented by models with power from 250 W to 1100 W, with a capacity from 1.2 m³ / h to 3.8 m³ / h. The downhole pump is part of the water supply system and is powered by an asynchronous AC motor.
The principle of the downhole pump: the engine transmits the movement of the shaft with the impeller, the impeller moves the fluid from the discharge chamber to the outlet nozzle, then under pressure enters the pipe
Installed in the same way as a conventional submersible pump. However, if the vibratory pump is used mainly for wells and lowered to a shallow depth, downhole models are placed deep in the shaft.
This complicates the maintenance and repair of equipment, and in the event of a cable break, lifting the apparatus is considered impossible.
The most powerful borehole pump Caliber NPCS-1.5 / 100, with a capacity of 1100 watts. Suitable for the deepest wells - up to 100 m
One of the models - NPCC-3,6 / 48 PPK - has special qualities. Multistage mechanism with floating wheels pumps the liquid with foreign inclusions, so it can be used for wells with a high content of sand in the liquid. The device has a capacity of 750 W and a capacity of 60 l / min.
“Caliber” products are not only submersible or surface centrifugal pumps.
Under the same label can be found and other equipment:
- pumping stations;
- fountain pumps;
- circulation pumps.
The stations of autonomous water supply of the SVD, in addition to the pump, include a hydroaccumulator and a pressure switch. Pumping stations in the country are very convenient, as they provide uninterrupted supply of water in the required quantity.
You can afford to take a bath or shower, use the washing machine. For comparison: a simple vibration pump is not designed to service a residential building.
A pressure control device (pressure switch) regulates the operation of the pumping station in the automatic mode: as soon as the pressure reaches a critical point, a shutdown occurs
The power of the proposed equipment is from 160 W to 1550 W, productivity - from 1.8 m³ / h to 3.9 m³ / h. To choose the right unit, it is necessary to calculate the total water consumption, the distance from the well to the house, the height of the lift.
Pumping stations for temporary use are installed directly on the street, near the well; devices for permanent water supply are mounted in the basement or in the back room, on a specially built stand
The fountain pumps of NFE are designed to supply purified water in the decoration systems of reservoirs - ponds, pools. From ordinary pumps, they differ in appearance - a compact plastic casing and a tube, ending with a spray nozzle.
Power models - 6 W, 35 W, 95 W, performance - from 380 l / h to 3500 l / h. The maximum head of the most powerful device is 3 m.
Circulation electric pumps NTS come in handy if you decide to equip the heating system. They are designed to operate on a network with a stable or slightly variable flow. The power of the instruments is from 72 W to 90 W, the capacity is from 2.4 m³ / h to 3.8 m³ / h.
The circulation apparatus is installed directly in the pipeline in a place convenient for maintenance, and expose the necessary power using a special switch

General characteristics of various groups will help you navigate the range of pumping products of the company Caliber, and now we will in more detail consider the properties and methods of application of some models of different species.
Model number 1 - NVT-210 / 40P
If you do not live at the dacha all the time, and come only in summer, use the plot of land for growing vegetables or flowers, pay attention to the compact, easy to use vibrating pump. It is designed to lift water from wells and wells with an internal diameter greater than 8 cm.
Productivity of 12 l / min is enough to water the beds, flower beds or berry bushes, the main thing to keep the water in the source clean, as the apparatus is not designed for pumping contaminated fluid.
If you carefully study the instructions, you will notice another warning: the pump should work no more than 2 hours, after which a 20-minute break is necessary.
For the full functioning of the equipment must be properly installed, attaching to it a rubber or polypropylene hose with a diameter of 18 mm to 22 mm
For hanging, you must use the nylon cord that comes with the sale. If you want to use a more durable metal cable or chain, still fix it with a nylon cord, otherwise you will break the eyes on the case.
For durable installation of the power cord, cable and hose should make a kind of bundle, intercepting them in several places with tape, and so that the hose hangs freely and does not bend. The whole structure needs to be fixed on the crossbar.
The pump must be completely submerged in water and not touch the walls of the shaft, otherwise the vibratory movements will damage both the walls and the device itself.
Preventive maintenance is a regular inspection of the device, for which it must be removed from the well. If the inlet is blocked, it should be cleaned, you can also change the rubber parts or reinforce the protective ring.
Model number 2 - NBC-900N-M
This model refers to self-priming equipmenthaving a multistage device. The device is useful to anyone who wants to establish a water supply or irrigation system in the garden.
A shallow well, a well or a natural reservoir with clean or slightly polluted water can be used as a source of water.
Technical characteristics of NBC-900N-M:
- power - 900 W;
- voltage from the power source - 220 V;
- productivity - 55 l / min;
- suction height - 8 m;
- lifting height - 42 m.
The multi-stage design allows pumping water with mechanical particles up to 3 mm in size, however, pure liquid prolongs the service life of the device. Replaceable parts, such as glands, rubber seals, are recommended to be changed from time to time, and the device itself can be disassembled and preventively cleaned.
If you use a surface pump periodically for watering a vegetable garden or lawn, it is not necessary to produce a stable installation - just install it near the source with water
Conditions for proper installation of equipment:
- level dry platform, located in close proximity to the source;
- free space in the engine area for ventilation;
- easy access for inspection and maintenance.
To operate the pump, connect the suction hose, lower it to a depth of about 2 m (the distance to the bottom is at least half a meter). The check valve will improve the operation of the device (it is not included in the package, must be purchased separately). Carefully check the tightness of the connections, as the penetration of air into the system dramatically reduces performance.
Model number 3 - NPTs-750 / 35N
Drainage equipment is a useful mechanism on a site with an artificial reservoir, a source of water supply and the likelihood of flood flooding.
Model NPC-750 is a submersible drainage pump of centrifugal type, which with the same efficiency pumps well, spring or rain water, and also easily copes with polluted fluid.
Technical characteristics of NPTs-750 / 35N:
- power - 750 W;
- voltage from the power source - 220 V;
- productivity - 13 m³ / hour;
- maximum head - 8 m;
- size of mechanical impurities - up to 35 mm.
The submersible pump must be in the water, the float device monitors the level of the liquid. When the level drops to a critical level, the float turns off the equipment, as soon as the water volume increases - the device turns on again. If the pump turns on / off too often (about 30 times / hour), the amount of water in the source is not enough.
Diagram of the device of the drainage pump Caliber NPTs-750 / 35N: in addition to the housing with the engine and the working pumping part, there is one more mandatory element - the float switch
Timely maintenance of the pump will increase the service life. Sometimes the engine stops working or the water supply stops.
It is necessary to check the power cord, clean the suction inlet, check the impeller functionality, and clean the system of air that has entered. If a check valve is installed, it should be checked and its health.
Model number 4 - NPTsS-1,5 / 65-750
If groundwater is deep in a suburban area, it is necessary to equip a well and acquire a special well pump. With a lifting height of not more than 65 m, the immersion centrifugal model Caliber NPSCS-1.5 / 65-750 is suitable.
The device can also be used to pump fluids from open reservoirs, but with one condition: the water must be clean.
Do not move water with clay sediment, debris, the presence of chemicals, corrosive inclusions. The presence of sand is allowed, but in a small amount - no more than 100 g / m³.
Equipment includes the pump itself, the power cord (15 m) with a plug, packaging and instructions. Cable for mounting the apparatus and supply line should be purchased separately
Technical characteristics of NPTSS-1,5 / 65-750:
- power - 750 W;
- voltage from the power source - 220 V;
- productivity - 1,5 m³ / hour;
- lifting height - 65 m;
- immersion depth - 5 m;
- electric cable length - 15 m.
Consider that the water supply can be different, since the pressure depends on many factors: depth, length of hoses, pipe diameter and etc. The downhole pump is part of the pumping station; therefore, control over its operation takes place in an automatic mode. If the equipment overheats or clogs, the relay is activated and turns off the mechanism.
The performance of this model is sufficient for servicing the summer cottage, but a more powerful apparatus is needed to build an efficient water supply system. We recommend to get acquainted with the rating of the best models of centrifugal pumps. in this material.
