WMTA Alloy Turbine Mag-Drive Pumps

Quick Contact

Product Category

Series WMTA
Mag-Drive Single Stage Turbine


WMTA machined billet regenerative turbine seal-less mag-drive pumps (superseding the MTA) can be constructed for high system pressures and special alloy configurations. All WMTA pumps are equipped with zero leakage magnetic couplings to meet the latest toxic emissions regulations. The absence of elaborate mechanical seal systems eliminates costly pump maintenance, lost production time and process contamination. Variations in head calculations have minimal effect on the flow of a turbine pump. Also, turbine pumps can be throttled to a required duty point without by-passing.

  • High head/ low flow capability minimizes by-pass requirements and prevents overheating of centrifugals and high head cavitation
  • Self balancing impeller – Zero axial thrust loading
  • Impeller design handles up to 20% entrained gas-ideal for pumping liquefied gases
  • No galling or metal to metal contact
  • Heavy duty alloy containment shell
  • High torque magnets, suitable for direct starting motors
