Cast Steel Pneumatic Diaphragm Pump For Sewage Diaphragm 7 Bar DN50

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

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.
