    摘要： A hydraulically driven diaphragm pumping machine comprises a plunger (6) that is slidably mounted in a middle part of the inside of the machine's hydraulic cylinder (5) between first and second bellow-like diaphragms (4,10). Ends of the plunger (6) are connected to the first and second bellows-like diaphragm (10) to define respective first and second outer annular spaces (a) that are independent of one another, and the pressure of fluid in the first annular space (a) is independent of the pressure of fluid in the second annular space (a). The machine may also comprise a hydromechanical switch for commutating a valve (102) to automatically control the supply of hydraulic fluid to the hydraulic cylinder at given moments of the machine's cycle.

    摘要： A hydraulically driven multicylinder diaphragm pumping machine has pump cylinders, each having at one end an inlet/outlet for fluid material to be pumped, and at the other end an inlet and outlet for hydraulic oil. A separator inside the pump cylinder is connected to the fluid-material end of the cylinder by a flexible diaphragm and to the fluid material end by another diaphragm, leaving an outer annular space that contains hydraulic fluid. The total volume of pumping hydraulic oil in the cylinders is maintained constant and by a device that compensates for thermal expansion and controls the necessary return flow of hydraulic oil for driving the pump. The separators move with an intake stroke at constant speed for all cylinders, and with pumping strokes function of the hydraulic oil delivery, so a lesser number of separators effect an intake stroke while a greater number of separators effect a discharge stroke.

    摘要： The invention generally concerns a submersible well pumping system comprising an axially elongated housing and a multi-chamber hydraulically driven diaphragm pump suspended in a well. The pump is driven by a self-contained, closed hydraulic system, activated by an electric, pneumatic or hydraulic motor. Several embodiments are used to reverse the flow of working fluid into and out of the working fluid sub-chambers of a two chambered diaphragm pump to operate the diaphragm pump over all operating conditions including starts and stops, and low speed. Generally, the embodiments sense the end of the pumping stroke, either directly or by time. When the end of the pumping stroke is sensed, the direction of flow is reversed by changing the state of a directional valve, operating a reversing clutch, or by deactivating one prime mover-auxiliary pump and activating a second that operates in the reverse direction.

    摘要： A pneumatically driven bellows pump includes a bellows that is reciprocable by a driving force effected by air. The bellows has an integral form of a bellows body, an expansion portion and a mounting portion. The mounting portion includes a threaded member, through which the bellows is brought into threaded engagement with a threaded member formed in a pump-driving member in such a manner as to seal the bellows.

    摘要： A submersible pump and filter unit for pumping and filtering acids comprises a removable pump cartridge (13) and filter unit (14) housed in respective cylindrical cavities (11, 12) in a housing (10). The pump cartridge (13) is a gas-driven double acting bellows unit with a cylindrical body (13A), the bellows (21, 22) and the body (13A) being formed of PTFE. Each bellows (21, 22) is at a respective end of a reciprocating rod (36) which is journaled coaxially in the body (13A) and which extends through a central aperture (16) in the body (13A). Control gear including a logic control valve (41) is housed in the aperture (16) and is thereby encased in PTFE structure and shielded from acid.
