Product Description
MARCH Series TEF-MAG pumps are rotating positive displacement pumps, external gear type and magnetically coupled.
TEF-MAG gear pumps generate low flows with high discharge pressures and approximately no pulsation.
The pump housing is made of resistant solid block plastics like PP or PVDF.
The internal hydraulic parts are made of non-metallic materials.
The power transmission of drive and pump happens in a contactless way with firm NdFeB or SmCo permanent magnets
So the pump is able to work without any shaft seals, which guarantees save supplies without any leakage of corrosive, toxic and explosive fluids.
Pumps for potentially explosive areas in zone 1 and 2, can be made out of PVDF.
Applications
The pumps have proven their performance in every application that requires lower flow rates and high pressures in combination with corrosive liquids and pulsation-free supplies.
Typical Applications:
- Biodiesel Facility
- Labor Equipment
- Pressure Increase
- Metering
- Plant Engineering
- Equipment Engineering
- Pharmaceutical-, Medical-, Bio- Engineering
