MAG DRIVE CENTRIFUGAL PUMPS

Mag-Drive Single Stage Turbine
Machined billet regenerative turbine seal-less mag-drive pumps (superseding the HMTA) can be constructed for high system pressures and special alloy configurations. All HMTAW 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.

Mag-Drive Multi Stage Turbine Mag-drive regenerative turbine pumps safely meet high head, low NPSA system requirements. Dynamic turbine impeller pumping action handles entrained gases to resist vapor locking. WMTA- LN multi-stage magnetic drive process pumps have been designed for applications requiring low flows at high heads but with low NPSHa. WMTA6 magnetic drive process pumps are top suction top discharge, two and three stage configurations, with a centrifugal first stage impeller / inducer to achieve low NPSH values. The second and third stage are regenerative turbine impellers that develop heads up to and 1000 feet at 60 Hz. WMTA6 magnetic drive process pumps have been specifically designed for liquefied gases (e.g. NH3, CO2, LPG, Butane, etc.). In Particular, refrigeration applications where the total absence of liquid vapor releases to plant and personnel, or CFC derivatives into the atmosphere that is harmful to the environment. The robust construction is achieved by machined billet from forged bars, and their seal less design, results in a safe, reliable and durable pump suitable for oil and gas refineries, chemical plants and OEM systems. When required, the WMTA6 pumps can be built in an API-685 configuration.
