摘要： An apparatus includes a base, including two motors and a mechanical coupling mechanism, and a cartridge shaped to define two stators and respective pairs of ports in fluidic communication with the stators. The cartridge is removably insertable into the base and includes two rotors disposed, respectively, within the stators. The mechanical coupling mechanism is configured to mechanically couple the rotors to the motors, respectively, such that, following insertion of the cartridge into the base, the motors rotate the rotors, thereby pumping fluid through the pairs of ports. Other embodiments are also described.

摘要： A rotary positive displacement pump comprises a housing rotationally supporting first and second parallel and axially extending drive shafts having constantly meshing gears such that the drive shafts rotate in opposite directions. A rotor casing is connected to a front side of the housing and has axial rear and front walls and a circumferential side wall jointly defining a pumping cavity. The casing houses first and second rotors drivingly connected to the first and second drive shafts respectively. The rotors rotate in opposite directions and mutually interact to provide a positive pumping effect on fluid product entering the cavity. First and second sealing arrangements prevent leakage of fluid product from the cavity towards the rear side of the casing along the first/second drive shafts. A heating device is detachably fastened to the rear casing wall to heat the casing, the first/second sealing arrangements and/or any fluid product within the casing.

摘要： A pump stage assembly including at least two pump suction stages and at least one pump pressure stage. The pump suction stages and the pump pressure stage are arranged spaced apart from one another in a pump housing PG and have a common drive shaft. The pump suction stages are formed by a first assembly of intermeshing external gearwheels that lie in a first plane, and the pump pressure stage is formed by a second assembly of intermeshing external gearwheels that lie in a second plane. A first delivery volume flow can be drawn in from a first region of a dry sump by a first pump suction stage, and a second delivery volume flow can be drawn in from a second region of the dry sump by a second pump suction stage. The two delivery volume flows intermix in the pump housing before they reach an oil tank.

摘要： A fluid pump includes a housing, a rotary shaft, and pump units which are contained in the housing and sucks in, pressurizes, and discharges fluid with being rotationally driven by the rotary shaft. The housing has a suction passage conducting the fluid from a suction port to the pump unit, a discharge passage conducting the fluid from the pump unit to a discharge port, a return passage returning a portion of the fluid flowing through the discharge passage to an upstream side of the pump unit, and a control valve controlling a flow of the returned fluid. The return passage is formed so as to conduct the returned fluid in the same direction as a flow of a sucked fluid flowing through the suction passage to make the returned fluid flow together with the sucked fluid.

摘要： A high-pressure pump comprising an elongated casing and a hollow interior formed along a central axis thereof. At least one partition may be axially fixed within the elongated casing such that it divides the hollow interior. First and second pressure differential devices may be disposed on opposite sides of the at least one partition and each have a rotary shaft extending there through. A first rotary shaft extending through the first pressure differential device may be axially fixed by the at least one partition and rotationally fixed to a second rotary shaft extending through the second pressure differential device. The high-pressure pump may be driven by a servomotor and used in a high-pressure press.
