Abstract
A dual intake centrifugal pump is provided. An impeller is mounted inside a pump housing, which is mounted within a pipe tee having an inlet, an outlet, and two ends closed with blind flanges. 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 blind flanges. An electric motor or dual hydraulic motors are mounted on each respective blind flange and cooperatively rotate the driveshaft. The inlet has a flange connection so that the entire assembly can be connected to a flanged outlet on a tank or to a flanged pipe for use as an inline booster pump.
Claims40
A pump apparatus, comprising:
- a. a sealed chamber having an inlet and an outlet;
- 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 sealed chamber;
- and
- 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, and wherein the driveshaft is mounted within the sealed chamber and connected to a motor configured for rotating the driveshaft.
A pump apparatus, comprising:
- a. a sealed chamber having an inlet and an outlet, wherein the inlet and the outlet each comprises a flange;
- 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 sealed chamber;
- 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 sealed chamber and extends through the opposing inlet openings of the pump housing, and wherein the ends of the driveshaft extend through openings in opposing sides of the sealed chamber;
- and
- d. at least one motor located on the exterior of the sealed chamber, wherein the at least one motor is connected to one end of the driveshaft and configured for rotating the driveshaft, and wherein the apparatus is free of internal bearings, mechanical seals, and wear plates.
