High Pressure Piston Pump For Fluent Materials

View page
US Patent:
50945963, Mar 10, 1992
Filed:
Jun 1, 1990
Appl. No.:
7/531850
Inventors:
Larry R. Erwin - North Hollywood CA
James E. Cavanaugh - Sunland CA
Robert D. Hetherington - Sunland CA
Assignee:
Binks Manufacturing Company - Franklin Park IL
International Classification:
F04B 3500
US Classification:
417397
Abstract:
A pump assembly especially adapted for pumping viscous and/or abrasive materials is comprised of a pair of opposed single acting piston pumps operated alternately by an interposed reciprocal actuator, and a static chamber interposed between each pump and the actuator; each pump comprising a pumping chamber having aligned inlet and outlet check valves in its peripheral wall and defining a straight line path of fluid flow diametrically through the chamber, a piston having its periphery spaced from the peripheral wall of the pumping chamber and having a relatively short stroke to maintain the straight line path of fluid flow through the chamber, and an annular seal extending from the peripheral wall of the pumping chamber toward the piston and bridging the gap between the periphery of the piston and the peripheral wall of the pumping chamber, the piston having sealed engagement with the seal throughout its reciprocal path of movement; the static chambers isolating the two pumps and the actuator from one another so that fluid leakage from any of them will not adversely affect the others. The pump assembly facilitates pressurized or forced feeding of fluent material to the two pumps, and therefore, the pumping of extremely viscous fluent materials, and utilization of the assembly in a wide variety of systems applications.

Pail Mount Pump With Integral Cover

US Patent:
46903089, Sep 1, 1987
Filed:
Jan 9, 1986
Appl. No.:
6/817527

James E. Cavanaugh - Sunland CA
Larry Erwin - North Hollywood CA
Robert D. Hetherington - Sunland CA
Assignee:
Binks Manufacturing Company - Franklin Park IL
International Classification:
B67D 552
US Classification:
222156
Abstract:
A pail mounted pump system having dual reciprocal pumps and pail cover in an integral design. The pump and pail cover are constructed in a single unit with a built-in intake siphon tubes. This arrangement provides dual pumps pumping the same fluid which keeps the system pumping should one of the pumps fail. The pail cover is formed with a recess and mounting holes for mounting a pump. A skirt on the cover has a flange on its inner surface forming an annulus which seats securely on the pail rim. A recirculation/agitation system is provided by a hose connected through a valve to the pump outlet recirculating fluid back to the pail through an aperture in the cover.
