2. Pump runs, but little or no product flowsCheck the pump for cavitation. Slowly reduce the pump speed to allow thick material to flow into the fluid chamber.Verify that the vacuum required for the height of the fluid suction rise is not greater than the vapour pressure of the material to be pumped Read More

I. Pump will not run or runs slowlyEnsure that the inlet pressure is at least 0.4 bar (5 psig) higher than the starting pressure and that the differential pressure (difference between inlet pressure and discharge pressure) is not less than 0.7 bar (10 psig).Check the inlet filter for debris.Check fo Read More

Diaphragm pumps, also known as control pumps, are the main type of actuators that operate with the aid of power to change fluid flow by accepting control signals from the modulation unit. Diaphragm pumps are generally composed of actuators and valves. The use of compressed air as a power source, for Read More
