    How much does a pneumatic diaphragm pump weigh?
    The Air Operated Pneumatic Diaphragm Pumps  weight depends on its port diameter, wet part material.
    Where are the diaphragm pumps available?
    We can offer a wide variety of diaphragm pump options to you, such as low pressure, high pressure, different diaphragm and wet part material.

    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.
