Description of diaphragm pump:
Pneumatic diaphragm pump is a new type of conveying equipment, which uses compressed air as the power source. It can be used for all kinds of ultra-low temperature liquids, corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids, which can all be exhausted.

Main features of diaphragm pump:
air-operated pneumatic suppliers pumps air diaphragm pump In the two symmetrical working chambers of the diaphragm pump, each is equipped with an elastic diaphragm, and the connecting rod integrates the two diaphragms into one. After the compressed air enters the air valve chamber from the intake joint of the pump, it pushes the diaphragms of the two working chambers and drives the diaphragms connected by the connecting rods to move synchronously. At the same time, the gas in the other working chamber is discharged out of the pump from the back of its diaphragm. When the piston reaches the end of the stroke, the valve mechanism will automatically introduce compressed air into the other working chamber, and push the diaphragm pump to move in the reverse direction, which forms a synchronous reciprocating movement of the two diaphragms. Two one-way ball valves are set in each working chamber. The reciprocating movement of the diaphragm causes the internal volume of the working chamber to change. As the two one-way ball valves alternately open and close, continuous suction and discharge of liquid will happen.
