IND-PTP - Gear Pumps

The video tutorial explains the types and operations of gear pumps, focusing on external and internal gear pumps. External gear pumps are known for high speed and medium pressure, while internal gear pumps are suitable for a wide range of viscosities and can run dry. The tutorial covers the advantages and disadvantages of each type, including their operational mechanisms and applications. It concludes with a request for feedback.

What is one of the main advantages of external gear pumps?

• They require high inlet pressure.

• They operate at high speeds.

• They can handle solid particles.

• They have no bushings in the liquid area.

Why are internal gear pumps suitable for a wide range of viscosity applications?

• They require high inlet pressure.

• They can run dry and are self-priming.

• They have a complex design.

• They operate at high speeds.

What is a disadvantage of internal gear pumps?

• They have high pressure limitations.

• They have multiple moving parts.

• They require moderate speeds.

• They cannot operate in both directions.

How does the crescent-shaped spacer function in an internal gear pump?

• It supports the shaft and bearings.

• It increases the speed of the pump.

• It acts as a seal to help force liquid out.

• It reduces the noise of the pump.

What role do the intermeshing teeth play in an internal gear pump?

• They increase the pump's speed.

• They help in sealing and forcing liquid out.

• They reduce the pump's pressure.

• They support the motor.
