MTH 140 • 240 • 180 • 280 Series regenerative turbine pumps rep- resent the most economical, high performance alternative for low ﬂow applications involving moderate to high pressures. By combining years of regenerative turbine pump designs with precision computer controlled manufacturing, the 100 • 200 Series delivers high efﬁciency pumping operation, even at low NPSH. High quality parts and an easily serviceable design provide low maintenance and long life.

LOW NPSH The 200 Series inducer style pumps are ideally suited 200 Series Inducer 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 characteristics is utilized as the pump’s ﬁrst stage impeller, accounting for the lower inlet head require- ment. This ﬁrst 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 240 • 280 Series pumps, depending on the pump model and capacity. 140 • 240 SERIES PUMPS
