    摘要: A hydraulic pump assembly having a main pump, a charge pump and an auxiliary pump driven by a single shaft is provided. A pair of hydraulic porting members cooperates to feed and distribute hydraulic fluid between the three pump units, and a single inlet may be used to provide hydraulic fluid to the charge pump and the auxiliary pump.

    摘要: A multi-stage pump system for use in desalination systems including a first stage S1 providing low pressure for priming the system a second stage S2 that is in fluid communication with the first stage and is primed by the low pressure from the first stage. The second stage S2B includes at least one reciprocating piston 122, in an enclosing cylinder 121, 121A and is attached to the two second flexible inflatable bladders 123. The piston 122 will move up and down within the cylinder 121 121A relative to the movement of the two second stage flexible bladders 123 due to priming by the first stage affecting their buoyancy. The driving fluid then passes into a passage 130 and is expelled to an outlet and Stage three (S3) at higher pressure when the first reciprocating member 122 proceeds through a complete stroke.

    摘要: A hydraulic pump apparatus having an internal sump formed by a housing having an internal portion and an end cap secured to the housing. A rotatable cylinder block is located in the sump and driven by an input shaft extending into the housing. The pump apparatus also has a system of hydraulic porting in fluid communication with the cylinder block. The porting includes a pair of system ports located on a first side of the hydraulic pump apparatus, a fluid inlet on a second side of the hydraulic pump apparatus, opposite the first side, and a bypass valve positioned on the second side adjacent to the fluid inlet.

    摘要: The present invention provides a pump unit including at least one hydraulic pump with inlet and outlet ports, a pump case for accommodating the hydraulic pump having an opening through which the hydraulic pump is insertable, and a lid, called a center section, closing the pump case. The center section forms a pair of inlet/outlet passages communicating an end with the inlet and outlet ports of the hydraulic pump and an end opening through a pump case abutting surface of the center section, and a first charging passage by which hydraulic fluid is fed through the pump case abutting surface of the center section. At least one of the pump case and the center section communicates the first charging passage with the pair of inlet/outlet passages via a first hydraulic fluid feeding valve preventing the reverse flow into said first charging passage.
