The third generation diaphragm pump Q/DBY3 series, combined with the characteristics of self-priming pump, Submersible pump, canned motor pump, mud pump and impurity pump, has a long service life, low noise, low vibration, no crash, easy maintenance, allows idling, self-priming start, safe explosion-proof, no sealing design, low material shearing, multi material and multi caliber selection, and is popular and loved by all industries;
It suitable for use in:
All kinds of highly toxic, flammable and volatile liquids.
All kinds of strong acid, strong alkali, strong corrosive liquids.
Pump and suck sewage and sediment in mines, galleries, tunnels and sewers.
Suction and delivery of various special media.
Also it can transport higher temperature medium 150 degree C.
A reversing valve suitable for a variety of specifications of pumps.
Pilot type reversing valve has a very high mechanical life, can ensure day to day operation.
Compared with other double diaphragm pumps, these are very few moving parts.
It has very good resistance to oxide corrosion.
Strong and durable, suitable for all kinds of complex working conditions.
It does not need lubricating oil, can idling.
