Non-Metallic Magnetic Coupled Gear Pump
Trend-setting technology – for aggressive chemical applications
MARCH PUMPEN Series TEF-MAG® gear pumps are corrosion resistant, non-metallic, rotating positive displacement pumps, external gear type and magnetically coupled.

TEF-MAG® gear pumps generate low flows with high discharge pressures with little or no pulsation. The pump housing is made of resistant solid block plastics like PP, PVDF or PTFE. The internal gears and shafts are made of highly corrosion resistant non-metallic materials. The drive system is leak-free, magnetically coupled using high strength Neodymium permanent magnets. The pump operates without any mechanical shaft seals, which guarantees no leakage of corrosive, toxic and explosive fluids.

Pumps are available for potentially explosive / flammable Zones 1 or 2.

Typical Applications:
The pumps have proven their performance in every application that requires lower flow rates and high discharge pressures in combination with corrosive liquids and pulsation-free delivery.

Typical Applications:
  • Biodiesel Plants
  • Waste Water Treatment
  • Environment Engineering
  • Metering Applications
  • Plant Engineering
  • Equipment Engineering
  • Pharmaceutical-, Medical-, Bio- Engineering
