Abstract
A centrifugal pump is provided for use with fluids, gases, and solids in connection with a drive shaft and a motor. The pump has a housing and at least a 30 degree sloped impeller mounted on the shaft within the housing. The housing has opposing inlet means on each side of the impeller and a discharge outlet. The impeller can be constructed as split through its center with an associated split housing or being an integral part.
Claims13
A self-priming immersible centrifugal pump apparatus for removing liquid and solids which pumps forward or in reverse comprising:
- a) a housing having a front wall and a rear wall, a discharge outlet opening in a top portion and opposing inlet means on opposite sides of the housing which creates equal pressure from both sides on an impeller;
- b) an impeller having a slope within and in spaced relationship with said housing, said impeller having a slope of at least 30 degrees and outwardly extending blades along its periphery for movement of flowable material outward to the discharge outlet,
- c) a drive shaft mounted in said housing and connectable to a motor means, said impeller and housing cooperating to discharge flowable material through said discharge outlet opening in response to rotation of said impeller.
A self-priming immersible centrifugal pump for use with liquids and solids which pumps forward or in reverse comprising a drive shaft, a motor means for driving said drive shaft, a housing having an impeller with at least one side sloped and mounting on said shaft in spaced relationship within said housing, inlet means in said housing on opposite sides of said housing and said impeller about the shaft so that there is equal pressure on both sides of the impeller, and outlet means for discharging liquids and solids in response to rotation of said impeller.
A fluid immersible self-priming discharge pump which pumps forward or in reverse comprising a hydraulic motor, a housing associated with said motor, said housing having opposing fluid inlet openings and a fluid discharge opening, a drive shaft within said housing operatively connected for rotation by said motor, an impeller means associated with said drive shaft and rotatable within said housing so as to draw fluid into said housing through said inlet openings, said impeller means being sloped on at least one side and having blades along its outward edge for discharging fluid through said discharge opening;
- said inlet openings being on both sides of said impeller means and creating substantially equal pressure on both sides of said impeller means, and means separate from said motor for activating said motor when said housing is immersed in a fluid, said impeller having a flat portion which is formed about the drive shaft to balance said impeller.
A self-priming immersible centrifugal pump apparatus for removing liquid and solids which pumps forward or in reverse comprising:
- a) a housing having a front wall and a rear wall, a discharge outlet opening in a top portion and opposing inlet means on opposite sides of the housing which creates equal pressure from both sides on an impeller;
- b) an impeller having a slope within and in spaced relationship with said housing, said impeller having a slope of at least 30 degrees and outwardly extending blades along its periphery for movement of flowable material outward to the discharge outlet,
- c) a drive shaft mounted in said housing and connectable to a motor means, said impeller and housing cooperating to discharge flowable material through said discharge outlet opening in response to rotation of said impeller, and
- d) a cutting device in association with the drive shaft to loosen sludge or particles for passage into said pump.
