| 231 | Control for progressive cavity pump | US09813583 | 2001-03-21 | US06530750B2 | 2003-03-11 | Ernest Bennett Mills |
| A progressive cavity pumping system includes a pump housing, a rotor member operatively received in the pump housing, a prime mover coupled to the rotor member for driving the rotor member in first and second directions and a controlling means for actuating the prime mover, wherein the controlling automatically causes the rotor member to be driven in the second direction after shut down or idling of the pumping system. A method of operating the pumping system includes automatically driving the rotor member in a second direction after initiating shut down or idling of the pumping system and prior to start up of the same. | ||||||
| 232 | Progressing cavity pump system for transporting high-solids, high-viscosity, dewatered materials | US09653371 | 2000-09-01 | US06491501B1 | 2002-12-10 | Alan G. Wild; Charles L. Snyder; Todd E. Brown; Richard A. Sliwinski |
| A system and method for transporting high-viscosity, high-solids, dewatered materials essentially includes a progressing cavity pump system utilizing a twin-screw feeder with an extended tunnel section. The feeding of the material into an extended tunnel section of the twin screw feeder creates a positive pressure, which assists in feeding the product into the suction housing of the progressing cavity pump, and correspondingly, into the pumping elements. This increases volumetric (fill) efficiency of the progressing cavity pump, thereby allowing a smaller pump to be used. The suction housing of the progressing cavity pump includes an auger positioned therein that is directly coupled to, and preferably integral with, the progressing cavity rotor. The universal joint is moved from the position in front of the stator entrance to a point behind the auger and suction inlet opening to improve flow of material from the suction housing to the progressing cavity pump elements. The inlet conduit coupled to the transition housing is angled slightly towards the direction of flow to further improve the flow efficiency and increase the fill rate of the progressing cavity pump elements. The feeder mechanism of the present system is radially set apart from the progressing cavity elements, where the materials are transported from the extended tunnel section of the feeder to the suction housing of the progressing cavity pump by a transition conduit. In one embodiment, the feeder is positioned above the progressing cavity pumping elements providing a taller system but with a relatively small footprint. | ||||||
| 233 | Sealless multiphase screw-pump-and-motor package | US09564274 | 2000-05-04 | US06457950B1 | 2002-10-01 | Paul Cooper; Allan J. Prang |
| A pump is disclosed, including a motor and a pump housing, for pumping mixed gas and liquid. The pump includes two intermeshed screw members for providing progressive cavities for transporting mixed fluids, within a pumping cavity, from a suction passage to a discharge reservoir of the pump housing. It further uses pumped product to provide cooling and lubrication to the motor and to bearings and timing gears of the screw members. By using pumped product for lubrication and cooling, the need for seals is eliminated, thereby reducing the need for maintenance. This makes the pump package advantageous for subsea deployment for use in pumping nearly depleted wells which may be manifolded together to provide adequate product flow. | ||||||

| A dialysis machine for the removal of toxic substances from biological fluids with agents for the decalcification of a dialysis liquid circulation is disclosed. The dialysis machine allows measurement of the degree of calcification of the dialysis liquid through the use of a blood leak detector or by measuring the dialysis machine pump flow or pump voltage. The invention also includes a process for automatically decalcifying the dialysis liquid circulation when a predetermined degree of calcification of the dialysis machine is measured. | ||||||
| 235 | Method and pump for pumping liquid containing solids | US801351 | 1997-02-19 | US5885065A | 1999-03-23 | Marshall Long |
| A pump for pumping a liquid containing solids comprises a housing having a first end and second end and an interior pump chamber. An inlet pipe leads to the pump chamber through the first end, and an outlet pipe leads from the pump chamber at the second end. A core having a vane extending therefrom rotates within the chamber. The core has hollow portions permitting material to move from the inlet pipe to the pump chamber and from the pump chamber to the outlet pipe. The vane extends from the core outwardly, seals against the housing, and works in cooperation with a pair of moving blades to draw material from the inlet pipe and expel the material through the outlet pipe. The blades, which are arcuate in shape and have curved ends, are operated by pneumatic cylinders and move from a retracted position in which they are positioned out of the pump chamber to a deployed position in which the curved end sealably engages the core. | ||||||
| 236 | Apparatus for intermittent transfer of fluid having vapor trap seal and vapor escape means | US462813 | 1995-06-05 | US5522709A | 1996-06-04 | George D. Rhoades |
| Fluid transfer apparatus comprising a fluid reservoir and a pump connected to the reservoir by a supply line, wherein the apparatus is configured so that vapor generated in the pump during periods of inoperation may escape from the pump cavity through the pump inlet, rather than being trapped in the pump cavity, and liquid may flow into the pump cavity from the supply line through the pump inlet to replace escaping vapor, thereby providing reliable pump start-up during intermittent operation. The apparatus may be employed to pump LNG for fueling of vehicles. Where LNG or another cryogenic fluid is being pumped, the pump is preferably driven by a motor located above the pump and connected thereto by an elongated shaft. Shaft seals may be provided to prevent the fluid being pumped from contacting the motor or the bearings supporting the motor shaft. A vapor trap may be provided beneath the shaft seals to prevent contact between liquid being pumped and the shaft seals. | ||||||

At least one of the end walls is provided with a shallow groove in a region between the axes, the groove being of a selected depth and width to permit solid material lodged between the rotors and at least one of the end walls to become disengaged and flushed out while allowing a minimum of fluid to flow through the groove causing pressure loss in the pump. | ||||||
