Pumps Disassembly and Assembly Quiz

What is the primary function of a centrifugal pump?

• To compress air

• To move fluid by converting kinetic energy to pressure energy

• To generate electricity

• To filter contaminants

Which of the following is NOT a key component of a centrifugal pump?

• Impeller

• Casing

• Piston

• Shaft

What is the first step before disassembling a centrifugal pump?

• Remove the impeller

• Drain the pump casing and isolate the power source

• Detach the bearings

• Apply lubrication

Which tool is commonly used to remove the impeller from the shaft?

• Torque wrench

• Bearing puller

• Screwdriver

• Hammer

What should be done before reassembling the centrifugal pump?

• Clean all components thoroughly

• Skip the inspection process

• Replace all parts, regardless of condition

• Use excessive force when aligning components

What is the function of the shaft in a centrifugal pump?

• To contain the fluid

• To support the casing

• To transfer rotational energy to the impeller

• To act as a pressure regulator

What should be checked after reassembling a centrifugal pump?

• Flow rate, pressure, and temperature

• Electrical circuit functionality

• Chemical properties of the fluid

• Speed of the motor alone

A common cause of excessive noise in a centrifugal pump is:

• Misaligned shaft or worn bearings

• Too much lubrication

• Overuse of gaskets

• High pressure in the suction line

If a centrifugal pump has reduced flow, what could be the likely cause?

• Worn impeller or clogged suction line

• Misaligned casing

• Excessive lubrication

• Too much torque applied to bolts

What is the purpose of lockout/tagout (LOTO) procedures?

• To increase the speed of assembly

• To ensure personal safety by isolating the power source

• To lubricate moving parts

• To clean pump components
