IND-PTP - An Introduction to Pumps

The video tutorial explains the function and classification of pumps, focusing on dynamic and positive displacement pumps. Dynamic pumps use centrifugal or axial motion to move liquids, while positive displacement pumps use rotary or reciprocating motion to displace a specific amount of fluid. The concept of slip, which is the fluid leakage past internal clearances, is discussed, highlighting its impact on pump efficiency. Safety measures, such as the use of relief valves, are emphasized to prevent damage. The tutorial concludes with an invitation for feedback.

What is the primary function of a pump?

• To decrease the pressure of liquids

• To move liquids from lower to higher pressure

• To move liquids from higher to lower pressure

• To maintain the same pressure in liquids

Which type of pump operates based on centrifugal force?

• Reciprocating pump

• Rotary pump

• Centrifugal pump

• Axial pump

What determines the amount of fluid displaced in dynamic pumps?

• The speed of the motor

• The discharge pressure

• The type of fluid

• The size of the pump

How do positive displacement pumps move liquids?

• By using gravitational force

• By using rotary or reciprocating motion

• By using axial force

• By using centrifugal force

What is a potential risk if a relief valve is not provided in a positive displacement pump?

• The pump will overheat

• The pump can be damaged

• The pump will stop working

• The pump will lose efficiency
