Understanding Loeb Pumps

Loeb pumps operate similarly to external gear pumps, with fluid flowing around the casing. Unlike gear pumps, the lobes in Loeb pumps do not touch. As the lobes disengage, they create an expanding volume on the pump's inlet side, allowing liquid to flow into the cavity and be trapped by the rotating lobes.

How do Loeb pumps compare to external gear pumps in terms of fluid movement?

• Fluid is expelled through the top.

• Fluid flows through the center of the casing.

• Fluid flows around the interior of the casing.

• Fluid is compressed in the center.

What is a key difference between Loeb pumps and external gear pumps?

• Loeb pumps are smaller in size.

• Loeb pumps have more gears.

• Loeb pumps have lobes that make contact.

• Loeb pumps have lobes that do not make contact.

What happens as the lobes in a Loeb pump come out of mesh?

• They create an expanding volume.

• They create a contracting volume.

• They increase pressure.

• They stop rotating.

Where does the liquid flow in a Loeb pump?

• Out of the top of the pump.

• Into the cavity created by the lobes.

• Into a separate chamber.

• Into the center of the pump.

What role do the rotating lobes play in a Loeb pump?

• They compress the liquid.

• They trap the liquid.

• They heat the liquid.

• They filter the liquid.
