OPERATING PRINCIPLE OF THE PUMP:

The HF pump series includes single impeller centrifugal electric pumps designed to achieve high flow rates at medium to low heads. The impeller, swinging on the drive shaft, is located directly in front of the suction pipe provided on the pump body. The special shape of the impeller ensures, with minimal hydraulic losses, radial movement of the fluid in the direction from the center to the periphery, during which the blades located inside the impeller channel transmit energy to the pumped fluid both in the form of pressure and in the form of an increase in flow speed. At the exit from the impeller, the liquid rushes into a spiral, which, together with a conical diffuser, ensures the conversion of part of the kinetic energy into pressure energy.

FIELD OF APPLICATION AND INSTALLATION OF THE PUMP:

The HF pump series is specially designed for use in the home, industry and agriculture, both in terms of its performance characteristics, its mechanical concept and the selection of materials used. The special shape of the spirals and impellers, characterized by wide passages, make the use of these pumps possible not only for pumping clean water, but also water of moderate contamination. High efficiency, as well as the ability to use under long-term and high load conditions, allow these pumps to be successfully used for gravity irrigation and sprinkling, for drawing water from lakes, rivers, wells, as well as in a variety of industries when it is necessary to achieve high flow rates at medium and low pressure values. The pump must be installed in places protected from atmospheric influences.
