Enclosed double suction pump

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.

Some liquids may contain a certain amount of solids, heavy oils, or similar heavy materials, which may result in the heavier materials accumulating in the bottom of a tank over a period of time. When the tank is eventually required to be pumped dry for cleaning, inspection, change of service, or other reasons, the material to be pumped out from the bottom of the tank may comprise a thick, viscous slurry or heavy sludge. Such materials may be difficult to remove from the tank because they may dama...

AI Technical Summary

Benefits of technology

The invention provides a pump that can safely and quickly pump heavy liquids from a tank without being too expensive. This solves a problem that previously existed.

Problems solved by technology

Some liquids may contain a certain amount of solids, heavy oils, or similar heavy materials, which may result in the heavier materials accumulating in the bottom of a tank over a period of time.

Such materials may be difficult to remove from the tank because they may damage or clog many conventional types of pumps.

Removing all of the material from the tank may require the tank to be vacuumed, which can be an expensive and time-consuming process.

In some cases, workers may have to enter the tank, which may expose workers to chemicals and hazardous work conditions.
