The difference between diaphragm pumps and magnetic pumps is reflected in various aspects, such as working principles, transport characteristics, pumping costs, structural design, performance parameters, etc. What they have in common is that they both have excellent leak-proof performance and can be Read More

Pneumatic diaphragm pumps have good physical properties, can be applied to any acid, alkali and all kinds of organic solvents in addition to molten alkali salts, the application range is extremely wide. Mastering the correct installation method of pneumatic diaphragm pumps can make diaphragm pumps m Read More

Pneumatic one-way diaphragm pump with reliable quality and long service life, low noise, low vibration, never die, fine workmanship and other six advantages, that is, to pump the flow of liquid, but also to transport some of the media not easy to flow, with self-priming pumps, submersible pumps, shi Read More

Pneumatic diaphragm pumps use compressed air as the power source, for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquids, can be pumped out.As the name implies, pneumatic double diaphragm pumps use compressed air rather than an electri Read More

Ensure that pneumatic diaphragm pumps are always in good operating or standby condition. All building installed living pneumatic diaphragm pumps, fire pumps, sprinkler pumps, make-up pumps, sewage pumps, air conditioning pneumatic diaphragm pumps. The maintenance staff of the management office is re 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

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

6 major roles of pneumatic diaphragm pumps1, due to the use of air for power, so the flow rate with the change in back pressure (outlet resistance) and automatic adjustment, suitable for use in high viscosity fluids. The working point of the centrifugal pump is set with water as the benchmark, if us Read More
