Turbine pumps offer smooth, long life performance
Available from fluids handling specialists Pump Engineering, the MTH range of regenerative turbine pumps is suited to applications such as boiler feed, high pressure cooling, refrigeration and CIP processes.
The pumps are available in direct drive, bareshaft, magnetic drive and canned rotor options.
According to Pump Engineering, they can replace multistage pumps, generating high heads in only a single stage.
The 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 has a propellar with 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 important advantage of the regenerative turbine pump is its ability to generate a very steeply rising head curve between minimum and maximum flow ensuring accurate flow control and stable operation.
