摘要:
A high feed centrifugal pump has a housing, a low-speed suction stage arranged in the housing and having an axis, at least one high-speed high pressure stage also arranged in the housing and axially displaced from the low speed suction stage, so that the housing has a suction side and a pressure side, and a drive operative for driving the stages independently of each other and including a first prime mover operative for driving the low speed-suction stage and a second prime mover operative for driving the high-speed high-pressure stage. One of the prime movers which is operative for driving a respective one of the stages is flanged to the housing at a respective one of the sides, whereas the other of the prime movers is flanged to the one prime mover in tandem arrangement.
