Magnetic-drive rotary vane pumps
Pumps of the MPA series are magnetic-drive, rotary positive displacement pumps, also known as sliding vane pumps, rotary vane pumps or vane pumps. Radially movable rotary vanes rotate in an eccentric stator casing. They produce a positive flow according to the displacement principle with high delivery pressure and an almost pulsation-free flow. The pump casing is made of stainless steel 1.4571. The pump hydraulics are available in the standard design in graphite with silicon carbide plain bearings; special materials are however available on request. Power is transmitted from the drive to the pump without contact by strong NdFeB permanent magnets. As a result the pump works without any shaft seal, so that safe and leak-free pumping of corrosive, toxic and explosive liquids is ensured. Pumps for potentially explosive areas of Zones 1 and 2 are available on request.

Applications
The pumps of this series have proven themselves wherever small flow rates have to be pumped under high pressure. Low-viscosity liquids without self-lubricating properties can also be pumped without problems.
Typical applications are:
- SNCR / SNR plants
- Biodiesel plants
- Laboratory technology
- Pressure boosting
- Metering
- Plant construction
- Apparatus engineering
- Pharmaceutical, medical and biotechnology
