Description of NOWA PKM 370-3536 Vortex Surface Pump
The NOWA PKM 370-3536 vortex surface pump is designed for pumping clean cold water in water supply and irrigation systems.
The NOWA PKM 370-3536 vortex surface pump belongs to vortex pumps with an open-type impeller. The pump operates stably even with a large number of air bubbles in the water. The pump is most often used when a high water head is required with a small pumping volume.
The pump can be used independently or as part of adaptive, automatic, and non-automatic pumping stations for:
- organizing autonomous water supply: supplying water from boreholes, wells, pools, reservoirs, and other open sources;
- increasing pressure in domestic main water pipelines 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 for NOWA PKM 370-3536 vortex surface pump:
- abrasive particle size must not exceed 0.05 mm;
- total mechanical impurity content in water must not exceed 20 g/m³;
- water should not have a high degree of mineralization — no more than 1500 g/m³ in dry residue;
- acidity (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.
