Electric Operated Diaphragm Pump Product Overview:

The cycloid needle gear reducer is used to drive the double diaphragm through the crankshaft slider mechanism for reciprocating movement, so that the volume of the working chamber changes alternately so that the liquid is constantly inhaled and discharged. At the same time, in recent years, the diaphragm material has made breakthrough progress, greatly extending the diaphragm, so it is more and more widely used to replace part of the centrifugal pump, screw pump in petrochemical, ceramics, metallurgy and other industries.


Electric Operated Diaphragm Pump Performance characteristics:

  1. No irrigation and water diversion is required, and the self-absorption capacity is up to 7 meters.

2. through the performance is good, the diameter of less than 10 mm particles, mud, etc. can pass effortlessly.

3. because the diaphragm will be delivered medium and drive mechanical parts separate, so the medium will never leak out. And pump itself without shaft seal, the service life is greatly extended. According to different media, the diaphragm can be divided into neoprene rubber, butadiene rubber, fluororubber, tetrafluorin, etc., can completely meet the requirements of different customers.

4. the pump body medium flow part, according to user requirements, can be divided into cast iron, stainless steel, PP,

Polypropylene,PVDF,aluminum alloy, motor is divided into ordinary type and explosion-proof type two.
