Cast steel pneumatic diaphragm pump for sewage, diaphragm: rubber,
head: 7 bar
Descriptions
Our pneumatic diaphragm pump, is also known as double acting air
diaphragm pump. It's driven by compressor air, are widely used for
the large volume transfer of various harshly liquid fluid, such as:
chemical, waste water, cement, paper pulpe, syrup, sewage, slurry,
honey, paint, oil, petroleum, etc. The wet part options are: PP
plastic, PVDF, stainless steel, aluminum alloy, cast steel, ductile
iron. As one professional air operated diaphragm pump manufacturer,
we've been in design and manufacture of diaphragm pump over 15
years. It has triple diaphragm films.
- Self priming

- No electric components
- Discharge outlet with protection
- Solid external sturcture
- Vast compatibility of fluid media
- Reduced internanal volume minimize the waste and easily clean
- Stainless steel bolt are corrosion resistant, and offer you
reasonable positioing and conveniently reassemble
- Unique designed three way control valve ensure no block operation,
easily parts maintenance, no need lubrication for air pipeline
- Worn resistance parts ensures precisely positioning of stem and
fast replacement

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.
