aluminum alloy Pnaumatic Diaphragm Pump manufacturer, pneumatic submersible pump

Descriptions

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. The diaphragm pumps are for the transfer of various harshly liquid fluid, such as: chemical, waste water, cement, paper pulpe, syrup, sewage, slurry, honey, paint, oil, petroleum, etc. It uses compressed air as a power source. The compressed air is shifted from one chamber to the other by a linked shaft that allows the chambers to move simultaneously. The pumps' wet part: PVDF, PP, stainless steel, cast steel, al-alloy, iron, etc. It's also known as double acting air diaphragm pump.

• 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.
