Side channel pumps for LPG

Side Channel Pumps, also known as "liquid film" pumps, are suitable for propane/butane and for transferring liquids across long distances, through narrow pipes. Most commonly used for tank emptying, tank filling, auto gas stations, cylinder filling and vaporizer feeding.

Product description

The side channel pump is designed to efficiently enhance the pumping process, aided by the multi-stage configuration which allows for generation of a higher differential pressure. The pumps come in six sizes with a maximum of nine stages, all having an added suction stage to enable the low NPSH values that make it ideal for pressurized liquids like LPG. The low speed makes the pump less vulnerable to cavitation and makes it more efficient than the comparable centrifugal pump.

  • A turbine pump

    Turbine pumps

    For low-flow/high head applications with high differential pressure, such as loading, unloading and filling of LPG, a turbine pump is a great choice. Also known as regenerative turbine pumps.
