    摘要： A pumping apparatus for pumping a liquid from a source to a target including a motor and pump driven by the motor. Sacrificial zinc components are utilized to minimize corrosion due to chlorine vapors. Measures to ensure that liquid is pumped in only one direction include the use of a full wave rectifier and/or a spacer incorporated with a swivel platform to limits the range of the angle between the motor shaft and the pump piston. To minimize the risk of rupturing the pump, the pump piston includes a relieved portion in fluid communication with a transverse bore of the pump housing when the piston is axially inserted within the pump housing in its full forward position. To prevent overheating and damage to the pump components, the pumping apparatus makes use of a positive temperature coefficient (PTC) resistor interposed between the motor and a current source.

    摘要： A medium and high pressure pump systems supplies a cryogenic fluid from a storage tank. The system comprises a pump that is operable to pump cryogenic liquid or a mixture of cryogenic liquid and vapor. The pump preferably comprises an inducer with at least two chambers and means for recycling excess fluid within the inducer instead of returning excess fluid to the storage tank. The reciprocating pump is preferably double acting such that fluid is discharged from the pump during both extension and retraction strokes.

    摘要： A combination airless paint pump and air compressor wherein a prime mover drives an eccentric cam wheel within an oil reservoir housing. A piston, movably received within a housing bore is engageable with a periphery of the cam wheel to load an hydraulic column open to the piston cylinder for oscillating a paint spray pump diaphragm. A second piston member, received in a bore open to the housing, is engageable with the periphery of the cam wheel spaced circumferentially of the paint pump piston. The second piston is operatively connected with an air pump diaphragm. Selector means are provided to disengage, selectively, either one of the pistons from contact with the cam wheel whereby the unit can operate in a paint only mode, an air only mode or a combination air and paint mode.

    摘要： The invention provides a fluid pump apparatus comprising a fluid inlet, a fluid outlet, a screw member and a rotatable pump member. The screw member has at least one helical screw blade configured to be rotated by a fluid flow stream and the rotatable pump member is in fluid communication with the fluid inlet and/or fluid outlet.
