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
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.
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
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
James G. Shaw - Draper 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
US Classification:
241 55, 241 92
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.

Check Valve For A Self-Priming Pump
US Patent:
2010031, Dec 16, 2010
Filed:
Aug 23, 2010
Appl. No.:
12/861479

Assignee:
ENVIROTECH PUMPSYSTEMS, INC. - Salt Lake City UT
International Classification:
F16K 15/03
US Classification:
1375272
Abstract:
A check valve of the flapper type structured for use in a self-primer pump is structured for attachment to the pump casing in a manner that facilitates servicing of the check valve, and includes securement means that are positioned external to the casing and a flapper that is located through an opening of the casing in a manner that enables the servicing of the valve without dropping the flapper or the hardware into the interior of the pump.
