DOUBLE SUCTION PUMP WITH AGITATORS

摘要

A double suction centrifugal pump is provided. An impeller is mounted inside a pump housing, which is mounted inside a three-dimensional frame made of two end plates connected by crossbars. The pump housing has opposing inlet openings on opposite sides of the housing so that fluid is sucked into the housing from both sides and discharged by the impeller. The impeller is mounted on a driveshaft that extends through the dual inlet openings and openings in each of the end plates. Dual hydraulic motors are mounted on the exterior of each respective end plate and cooperatively rotate the driveshaft. Agitators are attached to the driveshaft and rotate with the driveshaft. The agitators macerate solids such as vegetation or other organic matter so that the solid matter does not clog the pump intakes. The pump is effective for dredging and pumping sand and other abrasive solids and in severe service applications of high viscosity, high density fluids.

主权项

1.) A submersible pump apparatus, comprising:
a. a three-dimensional frame; b. a pump housing having a discharge outlet and opposing inlet openings on opposite sides of the pump housing, wherein the pump housing is mounted within the frame; c. an impeller mounted on a driveshaft within and in spaced relationship with the pump housing, wherein the impeller has outwardly extending blades for movement of flowable material outward to the discharge outlet, wherein the driveshaft is mounted within the frame and extends through the opposing inlet openings of the pump housing, and wherein the driveshaft is connected to a motor configured for rotating the driveshaft; and d. a plurality of agitators attached to the driveshaft, wherein at least one agitator is positioned on each side of the inlet openings.
