Sanitary Type Roller Rotor Pump

Under the centrifugal force generated by the rotor, the rollers move along the inner surface of the pump body, creating a high vacuum and discharge pressure. The pump is suitable for low-viscosity media and offers strong self-priming performance. No pre-filling is required before initial operation, making it ideal for transferring products from drums.

Product Performance

The specialised operating principle and choice of materials improve the pump’s resistance to wear and corrosion.
With its high vacuum capability, the pump can draw in low-viscosity media and mixtures of gas, liquid and solid particles from depths of up to 8 m.
Low noise, low pulsation, reliable sealing, a low failure rate, high efficiency, energy savings and a long service life.
When equipped with an inverter, the flow rate can be adjusted within a specified range, allowing the pump to be used as a metering pump.
Various connection types are available, including flange, threaded and clamp connections.
The mobile design is convenient and flexible, allowing the pump to be used whenever and wherever required.
The pump chamber does not need to be filled with medium before operation.
