nnnn200 Series Inducer
nnnnThe 200 Series inducer style pumps are ideally suited
nnnnto applications where available NPSH at the pump
nnnninlet is limited, such as boiler feed water deaerator
nnnnservice.
nnnnA centrifugal Francis vane impeller with low NPSH
nnnncharacteristics is utilized as the pump's first stage
nnnnimpeller, accounting for the lower inlet head
nnnnrequirement.
nnnnThis first stage impeller is used in conjunction with a
nnnnmulti-vane diffuser to provide the NPSH required by
nnnnthe second stage regenerative turbine.
nnnnAvailable NPSH as low as two feet can be effectively
nnnnhandled with 240 • 280 Series pumps, depending on
nnnnthe pump model and capacity.
