Rotary Piston Pumps

Rotary Piston Pump for viscous fluids, self priming, gentle pump action, positive displacement
Rotary Piston Pump for viscous fluids

GM Pump’s oscillating rotary piston pump is a unique pump specially manufactured for pumping fluids at extremely high viscosities (200 000 cps) and temperatures (300ºC). It is able to pump fluids such as chocolate, bitumin, oil and honey, fluids that can not normally be pumped do to their viscosity or high liquefaction point. The versatile rotary piston pump combines the technology of rotary pumps and piston pumps, catering to a broad section of the fluid pump industry. It is a positive displacement pump with a high self priming action.

The table below has an analysis of the different models that the rotary piston pump is available in. Pump curves can be displayed by clicking on the appropriate number in the pump curve column.
