SK5 - Pumps

What is the basic operating principle used to classify pumps?

• Temperature

• Viscosity

• Dynamic vs. Displacement

What is the main purpose of a pump?

• To create a vacuum

• To cool down fluids

• To decrease flow rate

• To increase pressure

Which component of a centrifugal pump generates velocity?

• Housing

• Casing

• Impeller

Which type of pump is suitable for high viscosity fluids?

• Gear Pump

• Diaphragm Pump

• Reciprocating Pump

• Centrifugal Pump

How does a Positive Displacement pump create pressure?

• By reducing velocity

• By increasing volume

• By creating a vacuum

• By system's response to flow

What is the main difference between Positive Displacement and Centrifugal pumps?

• Type of fluids handled

• Volume of fluid moved

• Pressure generation mechanism

• Speed of fluid movement

What is the advantage of Positive Displacement pumps in terms of flow rate variation?
