Compact turbine pumps from Pump Engineering

When pumping applications present the challenges of low flows at high pressures, very low NPSH for high temperatures or low vapour pressure liquids, a new pump range from Pump Engineering could be an ideal tool for efficiency.

The MTH range of pumps is designed for applications such as boiler feed, high pressure cooling, refrigeration and CIP process. These compact pumps, which are available in direct drive, bareshaft, magnetic drive and canned rotor options, can replace multistage 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.

The regenerative turbine pump 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.

MTH pumps are designed with the ability to generate a very steeply rising head curve between minimum and maximum flow ensuring accurate flow control and very stable operation.

The standard range of MTH pumps includes models which cover capacities from 1 to 500l/min and pressures up to 70bar.

Construction materials include iron, bronze and 316 stainless steel.
