Detail

Feature

QBY Air Operated Diaphragm Pumps is one the new pump series. It has the property of completely

pumping of the liquids with corrosion, particle, high viscosity, volatility, inflammability, explosiveness,

deadly poisonous, as well as ceramic pulp, jelly, glue and waste oil in oil tanker. The properties are close

to those of WLLDENPUMPS from Germany and MARIOWPUMPS from the U.S. The surface parts

which flows the liquid is made from stainless steel and aluminum alloy and cast iron. It is also made

of NBR, VITON, CR and PTFE based on the different liquids.

QBY Air Operated Diaphragm Pumps with air presser,steam and industrial gas can have a suction of 7 m,

maximum lift of 0-50m and flow of 0.8－30m3/h.
