Pump With Auxiliary Impeller Vane Inlet Device
View pageUS Patent:
6428268, Aug 6, 2002
Filed:
Aug 18, 2000
Appl. No.:
09/641572
Inventors:
Graeme R. Addie - Augusta GA
Peter Hergt - Frankenthal, DE
Peter Hergt - Frankenthal, DE
Assignee:
GIW Industries, Inc. - Grovetown GA
International Classification:
F01D 0000
US Classification:
415 1, 415206
Abstract:
Disclosed is a slurry conduit for connecting to a centrifugal pump for transporting a slurry mix of solids and liquids. The conduit includes an inclined upstream section having a reduced cross section whereby a concentration gradient formed within the slurry conduit is reduced. The inclined section forces any sliding bed or stratified slurry upwards as it goes towards the apex of the reduced section. The slurry entering the pump has a substantially monolithic or nonstriated composition, which reduces the wear on the pump.
Pump Impeller With Enhanced Vane Inlet Wear
View pageUS Patent:
6431831, Aug 13, 2002
Filed:
Aug 18, 2000
Appl. No.:
09/641430
Inventors:
Graeme R. Addie - Augusta GA
Peter Hergt - Frankenthal, DE
Peter Hergt - Frankenthal, DE
Assignee:
GIW Industries, Inc. - Grovetown GA
International Classification:
F04D 2924
US Classification:
415206, 416186 R, 416223 B
Abstract:
Disclosed is a centrifugal pump having inlet blade angles set to an angle which takes into account the velocity of the solids moving within a slurry steam to reduce the wear on the centrifugal pump. The centrifugal pump includes an impeller for moving the slurry. The impeller includes a plurality of vanes, wherein each vane has an inlet angle optimized for providing a substantially shock-free entry of slurry into the pump relative to a velocity profile of the solids contained within the lower half of the slurry profile to reduce wear on the pump.
Method And Apparatus For Air Testing Pumps
View pageUS Patent:
6450023, Sep 17, 2002
Filed:
Aug 7, 2000
Appl. No.:
09/634872
Inventors:
Graeme Addie - Grovetown GA
Peter Hergt - Ludwigshafen/Rhein, DE
Peter Hergt - Ludwigshafen/Rhein, DE
Assignee:
GIW Industries, Inc. - Grovetown GA
International Classification:
G01M 1900
US Classification:
73168, 7386169
Abstract:
A method and apparatus for determining the efficiency of a liquid pump using air as a test medium. The method includes determining the total power output of the pump operated on air and determining the input power necessary to operate the pump on air. The input power is corrected for power differences resulting from operation of the pump on air rather than a liquid to obtain a corrected power input. The corrected power input is then divided into the power output to determine pump efficiency. The apparatus for performing the method includes a liquid pump arrangement temporarily connected to a bearing arrangement. The bearing arrangement is designed to support only the static load of the pump and the dynamic loads generated by operating the pump on air. This allows a bearing housing to be used that is smaller in size and less expensive to use. In addition, because the pump is operated on air, the components for feeding the air are less expensive as is the medium itself.
Liner For Centrifugal Slurry Pumps
View pageUS Patent:
6582191, Jun 24, 2003
Filed:
Jan 22, 2002
Appl. No.:
10/054197
Inventors:
Graeme R. Addie - Martinez GA
Edward L. Ray - Evans GA
Edward L. Ray - Evans GA
Assignee:
GIW Industries, Inc. - Grovetown GA
International Classification:
F04D 2902
US Classification:
415197, 415204, 415206
Abstract:
An abrasion-resistant liner assembly for the suction branch of a centrifugal pump of the type having a suction connection for mating with a suction source, and a relief annulus formed in the suction connection, including a cylindrical liner, a groove formed in the outer surface of the liner and extending circumferentially around the liner, a seat ring positioned within the groove, and a seat ring holder positioned adjacent the seat ring on the inner end of the liner, wherein when the liner is positioned within the suction branch and the suction flange is mated with a suction source, the seat ring projects into the relief annulus, and the seat ring holder prevents axial movement of the liner.
Self-Compensating Clearance Seal For Centrifugal Pumps
View pageUS Patent:
6739829, May 25, 2004
Filed:
Jul 8, 2002
Appl. No.:
10/190871
Inventors:
Graeme R. Addie - Martinez GA
Assignee:
GIW Industries, Inc. - Grovetown GA
International Classification:
F04D 2906
US Classification:
415 1, 415110, 4151721, 4151741, 4151743, 4151744, 277369, 277387, 277429
Abstract:
A seal for use in a centrifugal pump of the type used for pumping an abrasive slurry, and having a sealing ring groove formed in the pump casing and an arrangement for supplying flushing water, comprising a radial seal having a sealing end, a water receiving end, and opposed sides and adapted for installation within the sealing ring groove, the radial seal having multiple openings formed therethrough for the passage of flushing water. The openings are dimensioned and located so that when flushing water is supplied to the water receiving end of the radial seal, the water flows through the openings, causing the radial seal to automatically moves to a self-compensating balanced position between the pump casing and a rotating pump impeller. This will reduce leakage between the pump casing and pump impeller and reduce wear of the pump surfaces.

International Classification:
F04D 29/08
US Classification:
4151721, 415196
Abstract:
Disclosed is a diverter for directing particles that cause wear in a slurry pump away from the stationary face of a slurry pump. The diverter comprises a protrusion that directs particles back into the collector of the pump to reduce the number of particles that go through the impeller nose gap. The protrusion extends from the suction liner face to the front shroud whereby particles can be deflected away from the suction liner face.
