Diaphragm has Teflon (PTFE), Viton, Buna-n, Neoprene, Santoprene, EPDM, etc. materials. That is imported material, the diaphragm stress of air operated diaphragm pump is reduced to the minimum, and the service life is extended.

The pump body installed with muffler, the delivery head and flow can pass the pneumatic valve open to realize the step less adjustment,  Effectively reduce air duct noise.

The valve seat materials are Teflon, Santoprene, Buna-n, etc.

The O-ring is also called the sealing ring, It is a kind of rubber sealing ring with circular cross section, which is the most common mechanical design for sealing.

The role of connecting rod is to connect the piston and the crankshaft, so that the reciprocating linear motion of the piston into the rotary motion of the crank, in order to output power.

The valve ball materials are Teflon, Santoprene, EPDM, ect. It has a very low friction coefficient, excellent self-lubrication, good corrosion resistance, dimensional stability, and no deformation.
