Where is the lobe pump used?

What is a Rotary Lobe Pump? Rotary lobe pumps are positive-displacement type pumps that use two or more lobes rotating around parallel shafts in the pump’s body to move liquids. They are widely used in the hygienic processing industries, including food & beverage processing and biopharmaceutical manufacturing.

What is a lobe in a pump?

Lobe pumps are similar to gear pumps in that the pump operates by two Y or I shaped lobes which are aligned vertically rotating within a pump casing. The timing is controlled via a gearbox and timing gear which prevents the lobes from making contact with each other.

What are lobe pumps similar to?

Lobe pumps are similar to external gear pumps in operation in that fluid flows around the interior of the casing. Unlike external gear pumps, however, the lobes do not make contact. Lobe contact is prevented by external timing gears located in the gearbox.

What is advantage of lobe pump?

Lobe pumps are frequently used in food applications because they are good at handling solids without inflicting damage to the product. Solid particle size can be much larger in lobe pumps than in other positive displacement types.

Can lobe pumps run dry?

There is not a tight relationship between the lobes and the housing. This allows for the pump to run dry for up to 30 minutes without damage.

Can lobe pumps pump water?

What are some applications in which rotary lobe pumps can operate? Membrane Filtration (water / wastewater) – this procedure can utilize water-permeable membranes to separate particles from water that needs to be cleaned.

Are lobe pumps self priming?

Rotary lobe pumps are self-priming, i.e. they can build up pressure to such a high level without external help that the medium can be sucked in independently. Their usually symmetrical design allows a reversal of the direction of rotation and thus of the direction of delivery.

Can you run a lobe pump dry?

Rotary lobe pumps are designed so the rotor does not touch any part of the housing. This allows the pump to run dry with only a small increase in temperature and without the risk of damage to any part of the unit.
