Diaphragm Pump New Twin Diaphragm Pump for Vibration Free Pumping

Editor: Dominik Stephan

Gardner Denver Thomas in Puchheim has extended its 5002F liquid diaphragm pump family with a Twin version. The new design positively improves the pump characteristics such as a smooth, almost vibration less operation over a broad pressure range, the company says.

The pressure height thus amounts to an impressive 25 m H20 and the suction height is 4.5 m H2O. With 1,000 ml/min free flow in parallel operation, the 5002F Twin pump has an especially high specific output, as the Twin version allows for an exceptionally compact design. (Picture: Gardner Denver)

Further the Twin configuration reduces the pump’s pulsation since two working strokes take place during one complete rotation of the motor. Hereby, a smaller motor torque with less current consumption is sufficient compared to single headed models with the same hydraulic performance, a design that has already proven its worth with the Jade family.

The new pump offers a reliable self priming in combination with a good compatibility to chemicals, Gardner Denver states. This is achieved by a mix of materials for all wetted components, such as hydrophobic treated EPDM elastomer in combination with graphite loaded high-performance plastic.
