Caliber water pumps help to solve the problem of water supply to the suburban area. Satisfying consumer demand, the manufacturer has launched the production of equipment with various technical characteristics in appropriate price categories, ranging from inexpensive models for irrigation and ending with powerful pumps, the work of which replaces the centralized water supply system.
Scope of application of submersible pumps Caliber
Caliber pumps can be divided into several groups according to their purpose:
- well;
- downhole;
- drainage;
- pumping stations.
The Caliber NBV (household vibration) line includes 7 models, they are used to raise liquid to a low height for irrigation and other household needs. Pumps of this series are lightweight (2.3-5.5 kg), do not take up much space and have a low cost, therefore it is easier to buy a new device than to repair a device that has become unusable. They are stored in dry rooms at positive air temperatures.
Caliber NBV consume power 210-300 W, their productivity is 7-12 l / min., Lifting height is 40-70 m. A convenient cord allows you to connect to a power supply at a distance of 10-40 m. The package includes a clamp and a cable made of nylon. The water supply hose is not included in the price of the device and must be purchased separately. During operation, the pump must be located 50 cm from the bottom.
- stainless steel (N);
- cast iron (Ch);
- plastic (P).
To increase the suction lift from 30 to 60 m, the Caliber centrifugal pumps are equipped with an ejector for water intake. The cost of popular models varies between 1000-3500 rubles. They have a high flow rate of 29-55 l / min. The ejector increases the fluid flow up to 80 l / min. The power of the devices is 380-900 watts. Installation of the pump is not higher than 6 m above the water level, since the maximum possible suction height is 7-9 m. Through the opening in the housing, the suction line is filled with liquid.
Pumps of this series, at the request of consumers, are used for the following types of work:
- intake of clean water from drinking sources;
- pumping groundwater to prevent waterlogging of the site;
- maintenance of ponds, artificial reservoirs, swimming pools;
- watering the garden and vegetable garden;
- irrigation of green spaces;
- pumping out water from flooded rooms and reservoirs.
The scope of their application is cold and hot water supply and sewerage systems, sewage cleaning.
Plastic pumps are easier to transport. More powerful devices are placed in a stainless steel case. This type of device cannot be used for pumping seawater, flammable liquids or solutions containing chemical compounds that cause corrosion.
Model overview and specifications
In accordance with the purpose, you can choose a universal submersible pump with the required technical characteristics.
Caliber NPTs-750 / 35N
The device is used for water supply, pool maintenance, pumping groundwater and draining basements. The centrifugal pump pumps clean and polluted water. It is connected to a 220 V socket, power consumption 750 W, has a capacity of 13 m3 / hour. The maximum head is 8m. It is allowed to pump dirty water with particles of 3.5 cm. The float monitors the immersion level, in a critical situation it gives a shutdown signal.
Caliber NPCS-1.5 / 65-750
The borehole pump lifts water from great depths up to 65 m or from open sources. It is used for pumping only clean liquid without clay deposits, debris and corrosive substances. Limitation on the presence of sand up to 100 g / m3.
Power consumption of the device is 750 W. A small capacity of up to 1.5 m3 / hour allows you to maintain a summer cottage. The pump is submerged in water up to 5 m, has a 15 m cable. The device is part of the pumping station, the operation is monitored in automatic mode.
Features of operation
Timely preventive examination will increase the service life. It consists in inspecting the integrity of the power cord, cleaning the suction hole, removing trapped air, checking the serviceability of the check valve.
Do not use borehole pumps when pumping viscous substances or contaminated water with fibrous or coarse inclusions.
Advantages and disadvantages of pumps Caliber
The main advantages are low cost, light weight, functionality without costly options. Overheating protection is provided by the temperature of the pumped liquid. Increasing the lift height will reduce performance. The warranty covers 12 months.
Reviews of the submersible pump caliber are not unambiguous. A lot of complaints are caused by eccentric shaft couplings, which cannot be purchased on order. This single moving element is the weak link in the design.
Customer Reviews
William: We bought a borehole pump NPCS-1,2 / 50 for watering the garden. The diameter of the device is 90 mm. Can be used only in summer, as the water in the hose freezes at sub-zero temperatures. The term of use is 2 years, from early spring to late autumn. The device perfectly copes with its purpose, supplying water through a 30 meter hose. Worked silently until rusted. The cost at the time of purchase was 3 thousand rubles.
Sergey: Our acquisition - NPTs-550 / 35P at a cost of 1.5 thousand rubles. It works in the summer for 3 years. Used to pump out dirty water from a well, to the garden threw a 40 m hose for irrigation. Performance is slightly lower than stated. I am going to buy the same pump for watering a potato field.
