In fire installations
In watering
General operating conditions
pumped water temperature no more than 35 oC;
work is not allowed with the crane closed (at Q = 0);
Before the first start-up, lower the НВП pump in a container with water, using a screwdriver, turn the shaft clockwise through the outlet pipe until water appears in the inside of the pump;
water should not contain sand and other visible mechanical impurities;
pumping of aggressive liquids is prohibited;
mineralization of water is allowed no more than 1500 g / m3;
the electric pump works only when completely immersed in water, while the distance from the bottom of the well to the pump should be at least 0.4 m, and the water level above the pump at least 1.0 m;
well flow rate must exceed pump capacity;
The minimum capacity of the electric pump must be at least 0.36 m3 / h.
