Patent ·
OSTI ID:6414702

A pump for drawing the condensate from a condenser and feeding it to a steam boiler is described, the combination comprising: an elongate casing adapted to be connected in a pipeline having an inlet for receiving the condensate from a steam condenser and an outlet for feeding the condensate to a steam boiler; a pump shaft mounted in said casing rotating in a pair of bearings spaced along said shaft and fixed in said casing; an electric motor mounted in said casing connected to one end of said shaft for driving it; control means for operating said electric motor; an inducer pump mounted at the other end of said shaft, driven by said shaft; a multiple stage centrifugal feed pump located in said casing driven by said shaft and receiving condensate from the inducer pump, pumping said condensate to a higher pressure suitable for feeding a steam boiler and delivering said condensate to the outlet of said pump, the multiple stage centrifugal feed pump being located adjacent said inducer pump; and said inducer pump being of the type to produce sufficient positive pressure for properly feeding condensate to said feed pump.
