Fern, there are a few considerations that will help you select the right pump. To select the progressive pump consider, 1. Pressure – The amount of pressure required to move the liquid that is pumped through the discharge port depends on the piping system. The difference between the pressure needed at the pump discharge and the pressure introduced into the pump suction is known as the differential pressure. 2. Viscosity – The Viscosity normal changes with temperature and should be considered while selecting the progressive cavity pump.

Rahul, not just pressure and viscosity, you should also consider capacity, temperature and operation time which choosing this pump. 1. Capacity – this is nothing but the rate of flow in gallons per minute 2.Temperature – since viscosity changes with temperature, you should also consider the temperature. 3. Operating time – whether the pump is to run intermittently or continuously, the operating cycle of the pump must be considered.
