摘要： A multi-stage fluid pump system can include a first stage configured to provide a first pressure and a second stage configured to provide a second pressure. The pump system can be configured to prevent output of the second stage in a first stage mode such that only the first pressure is output from the first stage and second stage and to allow output of the second stage in a multi-stage mode such that there is a combined pressure output from the first stage and the second stage.

摘要： A cryogenic rotary pump 2 for pressurising a flow of a cryogenic liquid and for dividing the flow into a first lower pressure and a second higher pressure stream has a series of pumping chambers 26, 54, and 84. A single rotary drive shaft 12 carries a rotary inducer 30 located in the chamber 26, a first impeller in the chamber 54, and a second impeller in the chamber 84. A liquid receiving chamber 40 is located intermediate the pumping chambers 26 and 54. A first outlet 44 from the pump 2 for the first lower pressure stream is contiguous to the chamber 40 and a second outlet 110 communicates with the pumping chamber 84.

摘要： The present invention relates to a pump (10) for fluids, said pump comprising: a pump housing (11); a power source (8) enclosed within said housing (11); a drive shaft connected to the power source (8); at least one pump inlet (14) arranged in the pump housing; a pump outlet(15) arranged in the pump housing; a first impeller (24) arranged within a first impeller chamber (25) and rotated by said drive shaft, and a second impeller (19) arranged within a second impeller chamber (20) and rotated by said drive shaft. The pump is changeable between a first configuration in which the first and second impeller are arranged in parallel to provide a high pumping capacity, and a second configuration in which the first and second impeller are arranged in series to provide a pump with less pumping capacity. The invention furthermore relates to a method for changing the pumping capacity of a pump (10) comprising a first impeller (24) and a second impeller (19).

摘要： A centrifugal pump (10), including a housing having a fluid inlet port (40) for receiving fluid at an initial pressure and an interior chamber defining a central axis. An impeller disk (16) defines first and second inlet areas (22, 24) and has a plurality (64(a)-(n)) of circumferentially spaced apart channels formed therein which extend from the inlet areas (22, 24) for conducting fluid from the inlet areas in a radially outward direction upon rotation of the impeller disk (16). A first collector (30) is formed by the housing for receiving the fluid from the first inlet area via the channels and a second collector (32) is formed by the housing for receiving fluid from the second inlet area via the channels. A cross-over conduit (48) is formed by the housing for conducting fluid from the first collector to the second inlet area of the impeller disk and an outlet (50) is formed by the housing for conducting fluid from the second collector (32).

摘要： The invention relates to a pump device (10) for treating liquids according to the principle of reverse osmosis, whereby two pumps are connected to a shaft and driven by a common motor, and a first pump delivers liquids into the casing of a second pump. A multi-stage first centrifugal pump (1.1) delivers a liquid with high pressure into a collecting chamber (17). The collecting chamber (17) comprises an inlet opening (18) for an additional supply (14) of highly pressurized liquid, and a second centrifugal pump (6.1), which is designed for high pump capacities (6.1) and low pressure increases is connected to the collecting chamber (17).
