Mechanical Seal For Large Pumps

US Patent:
2013002, Jan 24, 2013
Filed:
Sep 28, 2012
Appl. No.:
13/630376
Inventors:
James A. Monnot - Baton Rouge LA, US
Assignee:
Flowserve Management Company - Irving TX
International Classification:
F04D 29/12
US Classification:
415230, 277510
Abstract:
An improved mechanical seal assembly is provided for hydro transport applications and other similar applications, such as large high pressure slurry pumps. This mechanical seal is used in large scale pumps having an axially adjustable shaft to accommodate high wear applications by maintaining suitable pump performance. The improved seal is a cartridge seal that includes a stationary seal adapter which is mounted to a pump casing and has a static gasket sealingly contacting a movable gland which non-rotatably supports the stationary seal rings of a mechanical seal. Additional seal rings are rotatably supported on the shaft wherein these rotatable and non-rotatable seal components are movable axially with the shaft to improve pump performance in high-wear conditions. The gland and non-rotatable seal rings are supported on and move with a bearing housing, along with the shaft and its seal rings.

Slurry Pump Mechanical Seal Mounting Assembly

US Patent:
4575306, Mar 11, 1986
Filed:
Aug 28, 1984
Appl. No.:
6/644909
Inventors:
James A. Monnot - Baton Rouge LA
Assignee:
Kaiser Aluminum & Chemical Corporation - Oakland CA
International Classification:
F04D 2910, F04D 2960
US Classification:
415131
Abstract:
A mechanical seal mounting assembly for a centrifugal high solids concentration slurry pump is disclosed. A rotating seal ring adapter is secured to the pump's impeller drive shaft for rotation with the shaft. A stationary seal ring adapter is secured to a first end of a seal carrier which extends through the pump's back plate. A split gland ring is attached to a second end of the seal carrier and is supported by gland nuts threadedly carried on gland bolts. The gland bolts are attached to a bearing assembly for the pump shaft. Axial movement of the pump shaft to effect impeller clearance seal adjustment is possible without disturbing the mechanical seal adjustment. An O-ring is interposed between the pump back plate and the seal carrier and is held in place by an O-ring retainer secured to the back plate of the pump.
