AOK50 high flow flap valve Air Operated Diaphragm Pump liquid flow is spacious and good through performance, It is a Large particle passing capacity diaphragm pump, It has a strong capacity for the passage of large solid particles. allowing passage of solid particles with a maximum particle diameter of 40 mm. This aluminum alloy flap valve air operated diaphragm pump is very popular in chemical industry.
AOE100 air operated double diaphragm pump with sectional type structure, this self -priming pump can be used for conveying two different liquid by double diaphragm.
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 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 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.
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.
Air operated diaphragm pump is a kind of 1/2 Inch and 1inch standard pneumatic diaphragm pump using a new piezoelectric polymer material. The PVDF vacuum pump diaphragm is not only small density light weight, but also good flexibility, and has good chemical stability.
AOE aluminum air driven pump with simple structure, less wearing parts, At the same time, the slurry double diaphragm pump is a kind of corrosion resistant pneumatic diaphragm pump, And it can transport viscosity within the range of 10000 centipoises of liquid.
