What is radially split pump?
If a centrifugal pump’spump casing features a vertical joint relative to the shaft, this is referred to as a radially split design. The opposite is the axially split design.
What is axially split pump?
An axially split centrifugal pump features a pump casing design where the casing is split along the shaft centreline. See Fig. 1 Cargo oil pump. The opposite is a radially split design.
What is overhung centrifugal pump?
An overhung centrifugal pump uses one impeller installed on a shaft that is suspended at one end by bearings. Between bearing centrifugal pumps are favoured over overhung centrifugal pumps whenever higher flow rates, higher pressures, and heavier loading of the pump will occur.
What is meant by overhung pump?
Overhung Impeller Type: The impeller is mounted on the end of a shaft which is “overhung” from its bearing supports. – Close Coupled pumps where the impeller is mounted directly on the motor shaft – Separately coupled or frame mounted where the impeller is mounted on a separate pump shaft supported by its own bearings.
How does a split case pump work?
Split case centrifugal pumps feature a single double suction or two single suction impellers supported between bearings. The casing is split axially, with opposing suction and discharge flanges, greatly simplifying maintenance.
How do axial flow pumps work?
Axial flow pumps have a motor-driven rotor that directs flow along a path parallel to the axis of the pump. The fluid thus travels in a relatively straight direction, from the inlet pipe through the pump to the outlet pipe. Axial flow pumps are most often used as compressors in turbo-jet engines.
What is MSD pump?
The MSD pump has the broadest hydraulic coverage of any BB3 type multistage pump in the market. There are over 10 000 MSD pumps installed in product pipelines, boiler feed, water injection and even nuclear safety-related services around the globe.
What is the difference between end suction and split casing pump?
What is a horizontal split case pump? A type of centrifugal pump, in which the casing is split into two separate chambers. It’s different from an end suction pump or inline pump, in which the casing, the suction nozzle, and the discharge nozzle are all included in a single chamber.
What is an OH2 pump?
The pump type HZC ( OH2 ) is a series of horizontal overhung centerline mounted, single stage, single suction heavy duty centrifugal pumps with diffuser and volute design casings.
Why use split case pumps?
Split Case Pumps usually are used in higher flow rate applications than end suction pumps. Used for cooling water, plant make-up water, potable water distribution, fire pumps, pipelines, and other main process flows.
