The MTH series of regenerative turbine pumps from Pump Engineering is said to be ideal for applications involving low flows (130 litres per minute), high pressures (up to 70 bar) and heads up to 600m. A good example of this is the MTH M52 pumps recently supplied for a mechanical seal lubrication and pressurising application in oil production, where the benefits of low NPSH and smooth, balanced performance have been appreciated.
The MTH range of pumps is suitable for applications such as boiler feed, high-pressure cooling, refrigeration and cleaning-in-place (CIP) processes.
The compact pumps, which are available in direct-drive, bare-shaft, magnetic-drive and canned-rotor options, can replace multi-stage pumps, generating high heads in only a single stage.
This design allows the pump to handle hot liquids, refrigerants, liquefied gases and liquids with entrained air, for example gas dissolution systems, where the pump will self-vent carrying air bubbles with the fluid to the discharge port.
