150 • 250 • 160 • 260 • 170 • 270 Series50Hz Metric Edition

• Capacities to 470 LPM

• Heads to 350 Meters

• Low NPSH Requirements

• Flex Coupled

MTH 150 • 250 • 160 • 260 • 170 • 270 Series regenerative turbine pumps represent the most eco-nomical, high performance alterna-tive for low fl ow applications involv-ing moderate to high pressures. By combining years of regenerative turbine pump designs with preci-sion computer controlled manufac-turing, the 100 • 200 Series delivers high effi ciency pumping operation, even at low NPSH. High quality parts and an easily serviceable design provide low maintenance and long life.

LOW NPSH

200 Series InducerThe 200 Series inducer style pumps are ideally suited to applications where available NPSH at the pump inlet is limited, such as boiler feed water deaerator service.A centrifugal Francis vane impeller with low NPSH char-acteristics is utilized as the pump’s fi rst stage impeller, accounting for the lower inlet head requirement.This fi rst stage impeller is used in conjunction with a multi-vane diffuser to provide the NPSH required by the second stage regenerative turbine.Available NPSH as low as two feet can be effectively handled with 250 • 260 • 270 Series pumps, depending on the pump model and capacity.
