IND-PTP - Lobe Pumps

The video tutorial explains the operation of lobe pumps, highlighting their unique features such as non-contacting lobes and external timing gears. It details the fluid flow process within the pump, the advantages like handling medium solids and easy maintenance, and the disadvantages including the need for timing gears and reduced lift with thin liquids. The video concludes with an invitation for feedback.

What prevents the lobes in a lobe pump from making contact?

• Liquid pressure

• Pump shaft support bearings

• Internal timing gears

• External timing gears

How is the liquid transported within the casing of a lobe pump?

• Through the center of the lobes

• Between the lobes and the casing

• Over the top of the lobes

• Underneath the lobes

What happens when the lobes of a lobe pump mesh?

• They create a vacuum

• They stop the liquid flow

• They force liquid through the outlet port

• They increase the liquid temperature

Which of the following is an advantage of lobe pumps?

• Has a pulsating discharge

• Can pass medium solids

• Requires no timing gears

• Requires no seals

What is a disadvantage of using lobe pumps with thin liquids?

• Increased pressure

• Reduced pressure

• Reduced lift

• Increased lift
