sulfuric diaphragm pump, Pneumatic Diaphragm Pump for chemical
solution transfer
Descriptions
This 2 inch diaphragm pump is air powered diaphragm pump, or
pneumatic double diaphragm pump. It's designed for large flow
transfer of many kinds of liquid: flammable or explosive oil,
paint, pigment, paper pulp, or viscous fluid such as syrup, cement,
slurry, sewage, etc. The wet part options are: PP plastic, PVDF,
stainless steel, aluminum alloy, cast steel, ductile iron.Our
pnematic diaphragm pump are available with wet part in PVDF,
Polypropylene PP, al-alloy, cast steel, stainless steel, ductile
iron, etc. It has triple diaphragm films.

Comptetitve advantage
The air-driven double diaphragm transfer pumps. No electrical
components are required because the pumps are air-driven. RD series
pumps are run-dry safe and self-priming. The pump capacity can be
controlled by changing the pressure in the air supply. The air
control is designed for oilfree operation. The RD series pumps are
ideally suited for the transport of liquid chemicals. It transports
media at up 6,700 l/h and up to a discharge lift of 70 m.
As the pump capacity is highly dependent on the back pressure, the
performance curve must always be observed. At the sametime, the differential pressure between the hydraulic and
pneumatic sides should not exceed 2 bar. Higher values reduce the
service life of the pump. When selecting pumps, check the material
compatibility. In addition, consider the density, viscosity and
temperature of the transported medium.
