Description of NOWA CPMV 1100-33120 Vertical Centrifugal Surface Pump
The NOWA CPMV 1100-33120 vertical centrifugal surface pump is designed for pumping clean cold water in water supply and irrigation systems.
The NOWA CPMV 1100-33120 vertical centrifugal surface pump belongs to the class of single-stage cantilever centrifugal pumps with a single-sided inlet. It ensures stable water flow parameters during changing operating conditions, smooth changes in motor load, for example, during power supply voltage fluctuations. It is easily integrated into any type of water supply system, including in parallel with other pumps, and is less sensitive to the presence of solid particles and contaminants in the water. It is most often used when a large volume of pumped water is required at low or medium head.
The pump can be used independently or as part of adaptive, automatic, and non-automatic pumping stations for:
- organizing autonomous water supply: pumping water from wells, boreholes, pools, reservoirs, and other open sources;
- increasing pressure in domestic main water pipes and water supply systems;
- draining pools, tanks, and containers.
The pump is not intended for pumping mineral and sea water, chemically active, aggressive, and flammable liquids and solutions. The water pumped by the pump must not contain abrasive particles or long-fiber inclusions.
Operating conditions:
- the size of abrasive particles must not exceed 0.05 mm;
- the total content of mechanical impurities in the water must not exceed 20 g/m³;
- the water should not have a high degree of mineralization — no more than 1500 g/m³ in dry residue;
- the acidity index (pH) must be in the range from 6.5 to 9.5;
- chloride content — no more than 350 g/m³, hydrogen sulfide — no more than 1.5 g/m³;
- operating temperature range of pumped water — from +4 °С to +40 °С;
- suction depth no more than 8 m.
