Centrifugal Pump

When the fluid is forced away from the center, or the eye of the impeller, a ____ is created thus resulting to flowing of more liquid.

• centrifugal force

• positive displacement

• vacuum

• negative displacement

Type of a centrifugal pump that borrows characteristics from both radial flow and axial flow pumps.

• Radial Flow Pump

• Mixed Flow Pump

• Axial Flow Pump

It is a type of pump casing design that has an offset impeller creating a curved funnel with an increasing cross-sectional area towards the pump outlet which causes the fluid pressure to increase towards the outlet.

• vortex

• volute

• diffuser

• rotary

It is used for a wide variety of industrial applications thanks to their increased efficiency and ability to pump fluids at higher pressures.

• Multistage centrifugal pumps

• Single stage pump

• Circulator pump

It is a rotating component of a centrifugal pump that accelerates fluid outward from the center of rotation, thus transferring energy from the motor that drives the pump to the fluid being pumped.

• Impeller

• Coupling

• Shaft

• Stuffing Box

Centrifugal pumps can also develop a phenomenon called “cavitation”.

• True

• False

When the sealing is achieved by means of packing, the chamber is referred to as a ___________.

• Stuffing Box

• Nozzle

• Casing

• Seal Chamber

A pump moves fluids from ___ pressure to ____ pressure.

• lower, higher

• lower, atmospheric

• higher, lower

• higher, atmospheric

When the sealing is achieved by means of a mechanical seal, the chamber is commonly referred to as a ___________.

• Stuffing Box

• Nozzle

• Casing

• Seal Chamber

Type of a centrifugal pump where the liquid enters at the center of the impeller and is directed out along the impeller blades in a direction at right angles to the pump shaft.

• Radial Flow Pump

• Mixed Flow Pump

• Axial Flow Pump
