Pneumatic diaphragm pump is a new type of conveying machinery, is currently a new type of domestic pump. Using air compressor compressed air as the power source, for a variety of corrosive liquids, liquids with particles, high viscosity, volatile, flammable, highly toxic liquids, can be pumped out a Read More

Pneumatic diaphragm pump is a kind of compressed air as the power, by the diaphragm reciprocating deformation caused by volume changes in the volume of the pump, its working principle is similar to the plunger pump, due to the characteristics of the working principle of pneumatic diaphragm pump, so Read More

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
