The only moving part in the centrifugal pump which is subjected to be in contact with the fluid is

• motor

• casing

• impeller

• bearings

Which part of a centrifugal pump applies high energy force to the fluid?

• shaft

• casing

• impeller

• bearings

The part that support the pump shaft is the

• shaft

• casing

• impeller

• bearings

Which one of the following factors will NOT affect the pump capacity of a centrifugal pump?

• size of impeller

• type of impeller

• speed of rotation

• the position of the pump

The alignment of a centrifugal pump and its driver should be checked

• monthly

• quarterly

• half annually

• annually

The bearing interior parts of a centrifugal pump should be cleaned

• monthly

• quarterly

• half annually

• annually

The liquid entering the eye of impeller is thrown out from the blade at high speed due to

• center force

• centrifugal force

• reciprocating force

• thermal force

The component that prevents the water leakage in a centrifugal pump is

• mechanical seal

• impeller

• bearing

• casing

The water of a centrifugal pump enters from the

• top part of the casing

• bottom part of the casing

• center of the casing

• back part of the casing

The purpose of the casing of a centrifugal pump is to

• direct the flow quantity

• protect the pump

• direct the flow direction

• increase the water quantity
