    摘要： A precision pump system having a motor driver for accurately and repeatedly delivering process fluid, (e.g., photo chemicals) using a pumping fluid with minimal process fluid loss to a fabrication process and whereby the motor driver can be easily and quickly replaced without interrupting the fluid flow path. This is accomplished with the use of a gas removal reservoir having at least one vertical partition therein and at least one free end near a top side of the gas removal reservoir where both the input and output to the gas removal reservoir are located on a bottom surface and a pumping fluid reservoir that are associated with the pump, either integrated with the pump or closely adjacent. In addition, this precision pump system can be remotely monitored, viewed and controlled over the Internet. In addition, trapped process fluid within a downstream filtering block can be recirculated to the gas removal reservoir when trapped gas in the filter is removed. Furthermore, a nitrogen gas source is connected to the gas removal reservoir via a valve in case a need to insert a gas is required. Alternative system embodiments are shown for recirculating process fluid back to the gas removal reservoir and/or the source line. Another alternative system has the pumping chamber coupled to the gas removal reservoir input.

    摘要： A liquid pumping, handling and spraying system for liquid compositions and especially those liquid coating compositions having a suspension of metal particulate therein which tends to settle out of suspension of metal particulate therein which tends to settle out of suspension quite rapidly and which includes metal particulate having an affinity for adherence to metal surfaces. A fluid supply system is provided which accomplishes continuous agitation of the liquid composition to sprayed to maintain the metal particulate thereof in properly entrained suspension and even distribution with the liquid carrier fluid and which permits the use of low cost, lightweight containers for the liquid supply. A packingless pump is provided for pressurized delivery of the liquid composition from the supply container to a packingless spray gun. The packingless pump achieves pumping of liquid by hydro mechanical deformation of polymer variable volume pump chambers which induce intermittent suction and pressurization of the liquid for pumping and which have externally mounted check valve heads for controlling the flowing of the pumped liquid from the supply container to the spray gun. The packingless spray gun employs a body of resilient polymer which functions as a columnar spring to control the opening and closing movement of a spray valve assembly. Valve seats of the check valve head and spray gun assembly may be of flexible nature to ensure efficient separation of metal particulate therefrom. Metal operational components of the check valve head and spray gun, such as valve stems and valves define outer surfaces composed of titanium to minimize metal particulate adherence thereto.

    摘要： In a membrane pump for very high pressure, an axially moveable control member is provided in a body which borders a fluid handling chamber to form a narrow annular clearance around the control member and to form at the axial movement of the control member a cross-sectional area for big flow-through fluid quantities and temporarily a very narrow clearance for the prevention of deflection of portions of the membrane over the flow-through fluid passage.

    摘要： A diaphragm pump especially suited for use in a high pressure application. The pump is devised to replenish any hydraulic fluid lost from a motor chamber, especially that fluid forced past the seals circumscribing a reciprocating plunger that is partially inserted into the motor chamber and is used as a means to alternately generate and release the high pressure that must be generated in the motor chamber to overcome the opposing high pressures existing in a pumping chamber containing a transient fluid. The motor chamber and the pumping chamber are separated by a diaphragm that is displaced according to the pressures in the motor chamber and the pumping chamber. Whenever the pressure generated in the motor chamber is such that the pressure in the pumping chamber is overcome, the pumping chamber shrinks in size and the transient fluid is expelled from the pumping chamber. Whenever the pressure in the motor chamber is released, the pumping chamber increases in size and the transient fluid is drawn into the pumping chamber.
