Pump Impeller And Chopper Plate For A Centrifugal Pump

US Patent:
7455251, Nov 25, 2008
Filed:
Oct 11, 2006
Appl. No.:
11/546137
Inventors:
Brandon R. Doering - West Jordan UT, US
James C. Harmon - Salt Lake City UT, US
James G. Shaw - Draper UT, US
Assignee:
EnviroTech Pumpsystems, Inc. - Salt Lake City UT
International Classification:
B02C 23/36, F01D 5/12
US Classification:
241 4608, 2411856, 4151211
Abstract:
A centrifugal pump of the chopper type is disclosed which is structured with a chopper plate and impeller that are configured with an open eye or “hubless” arrangement such that processing of solids through the pump does not result in clogging of solids at or near the center of the impeller, thereby producing a dead zone. Because the configuration of the chopper pump of the present invention avoids the development of a central dead zone or clogging of solids, and provides for flow of solids and fluid through the eye of the impeller, pump efficiencies are markedly improved.

Pump Impeller And Chopper Plate For A Centrifugal Pump

US Patent:
2005004, Mar 3, 2005
Filed:
Jun 25, 2004
Appl. No.:
10/877760
Inventors:
Brandon Doering - West Jordan UT, US

Impeller And Cutting Elements For Centrifugal Chopper Pumps

US Patent:
7118327, Oct 10, 2006
Filed:
Jul 16, 2004
Appl. No.:
10/893506
Inventors:
Brandon R. Doering - West Jordan UT, US
James C. Harmon - Salt Lake City UT, US
Assignee:
EnviroTech Pumpsystems, Inc. - Salt Lake City UT
International Classification:
F04D 29/70
US Classification:
4151211, 4151212
Abstract:
A pump impeller and associated cutting elements are disclosed which are especially designed and positioned near the periphery of the impeller to reduce the size of entrained solids in a pumped fluid, or slurry, and to expel such solids from the impeller, drive shaft and associated sealing mechanisms.

Component Assembly For Reconfiguring A Centrifugal Pump

US Patent:
7121794, Oct 17, 2006
Filed:
Jun 1, 2004
Appl. No.:
10/858350
Inventors:
David P. Borrowman - Murray UT, US
Brandon R. Doering - West Jordan UT, US
Assignee:
EnviroTech Pumpsystems, Inc. - Salt Lake City UT
International Classification:
F04D 29/42
US Classification:
415204, 415206, 4152141, 415912, 294011, 29888021, 298891
Abstract:
A component assembly is provided for converting a conventional centrifugal pump, of the vortex impeller type for example, to a different type of centrifugal pump, such as a spiral impeller pump. The component assembly enables a resident centrifugal pump to be converted to a more efficient or appropriate type of industrial pump when conditions or application processing requirements change, and avoids the need to entirely replace an installed pump for a new type of pump.

Apparatus For Axial Adjustment Of Chopper Pump Clearances

US Patent:
7168915, Jan 30, 2007
Filed:
Jul 20, 2004
Appl. No.:
10/894731
Inventors:
Brandon R. Doering - West Jordan UT, US
James C. Harmon - Salt Lake City UT, US
Assignee:
Envirotech Pumpsystems, Inc. - Salt Lake City UT
International Classification:
F04D 29/042
US Classification:
4151211, 415131, 415132
Abstract:
Axial adjustment apparatus is provided in a centrifugal pump to effect adjustment of the impeller relative to adjacent pump elements. Specifically preferred is adjustment apparatus in a chopper pump that provides adjustment of the impeller relative to a chopper plate to facilitate continuous efficient cutting of solids by the pump. The adjustment apparatus may also include adjustment structure for providing axial adjustment between the impeller and a plate-like member positioned adjacent the drive side of the impeller to effect adjustment of cutting tolerances in cutting elements positioned between the impeller and plate-like member. The invention further includes a seal mechanism configured and positioned to retain the seal height of the seals throughout continuous adjustment of the impeller.

Pump Impeller And Chopper Plate For A Centrifugal Pump

US Patent:
7234657, Jun 26, 2007
Filed:
Jul 14, 2006
Appl. No.:
11/486530
Inventors:
Brandon R. Doering - West Jordan UT, US
James C. Harmon - Salt Lake City UT, US

Assignee:
Envirotech Pumpsystems, Inc. - Salt Lake City UT
International Classification:
B02B 1/00, B02C 17/02
