QBY Series Pneumatic Diaphragm Pump Product Description
The Series QBY pneumatic diaphragm pumps are operated with
compressed air.Our diaphragm pumps work as well as those imported
from Germany or USA,suitable for pumping fluids with particles and
other various liquids which are highly viscous,volatile,corrosive
or toxic,as well as colloids. The pump body is made of aluminum
alloys,cast iron or stainless steel.
The diaphragm is made of high quality rubber such as nitrile
rubber,chloronorgutta rubber,fluoroine rubber. The diaphragm pumps
are widely used in the petroleum industry,chemical
industry,electronic industry,ceramic industry,food and textile
industry.
