Diaphragm Transfer Pump General Description
Diaphragm Transfer Pump offers high volume delivery even at low air pressure and a b road
range of material compatibility options available.Refer to the
model and option chart.The BSK pump is provided with the
modularized air motor and fluid section.
The air operated diaphragm pump alternately generates the intake
fluid pressure and positive fluid pressure in the fluid chamber by
using the pressure difference in the air chamber. The ball valve
can ensure the forward flow of fluid.
Pump cycling will begin as air pressure is applied and it will
continue to pump and keep up with the demand. It will build and
maintain line pres -sure and will stop cycling once maximum line
pressure is reached (dis -pensing device closed) and will resume
pumping as needed.
Diaphragm Transfer Pump Advantage:
1. Easy to operate.
2. Safe and efficient
3. Large capacity of transferring powder
