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.

MTH pump

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.

Key features and benefits 

  • The MTH series is characterised by its impeller, which has a large number of blades machined into both sides of its periphery. Fluid enters the impeller at its outside diameter and is accelerated as it passes from blade to blade, exiting the pump at the same radius as the inlet.
  • The row of blades located on each side of the impeller minimises axial thrust; in effect, it is two impellers in one, operating within identical channels on the casing and the cover, which allows the impeller to float freely and find its own equilibrium.
  • Another advantage of the regenerative turbine pump is its ability to generate a steeply rising head curve between minimum and maximum flow, ensuring accurate flow control and stable operation.
  • The standard range of MTH pumps includes models that cover capacities from 1–500 litres per minute and pressures up to 70 bar.
  • Construction materials include iron, bronze and 316 stainless steel.
