What are the advantages of lobe pumps?

– Lobe pumps can handle solids, slurries, pastes and many liquid.
– No metal-to-metal contact.
– Superior CIP(Cleaning in Place) /SIP(Sterilization in Place) capabilities.
– Long-term dry run (with lubrication to seals).
– Non-pulsating discharge.

What is the difference between gear pump and lobe pump?

Gear pumps are characterized by close internal clearances and tight gear meshing action. Lobes pump product similarly to external gear pumps, but the lobes do not contact and can be made from stainless steel, which makes them excellent candidates for food applications.

Can you run a lobe pump dry?

Dry run capability 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.6 Dec 2016

What is Lobe and vane pump?

Vane Pumps are ideal for low-viscosity and non-lubricating liquids. Sliding Vane Pumps are used for vacuum services. Lobe Pumps are used in food and beverage processing. Lobe Pumps can handle both low and high viscosity fluids.22 Oct 2020

What is a lobe in a pump?

What is a lobe pump? A type of positive displacement pump that moves liquid by passing it across two rotors containing lobes. Each rotor is located on its own shaft, with the lobes meshing as they rotate inside the pump casing.

How does a lobe pump work?

Lobe pumps are similar to external gear pumps in operation in that fluid flows around the interior of the casing. As the lobes come out of mesh, they create expanding volume on the inlet side of the pump. Liquid flows into the cavity and is trapped by the lobes as they rotate.

Does lobe pump need 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 positive displacement pumps run dry?

Certain Positive Displacement Pumps can run dry i.e Air Operated Diaphragm pumps have no parts requiring lubrication or no close clearances between parts. Peristaltic pumps can run dry as the hose is lubricated in a bath of its own fluid. Other types of PD pumps should not be run dry.

Can progressive cavity pump run dry?

Another limitation of progressive cavity pumps is that they are completely unable to run dry. If the pump runs dry, the stator is immediately damaged. A perfect solution for these types of difficult applications is Boyser’s industrial peristaltic pump.28 Mar 2017

When we should use 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.1 Mar 2021

Is a lobe pump a gear pump?

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 the difference between gear pump and piston pump?

A piston pump typically uses reciprocating motion to create rotation along an axis. Some piston pumps have variable displacement, while others have a fixed displacement design. Gear pumps use gears or cogs to transfer fluids. The cogs are tightly aligned to create suction as they draw liquid in and discharge it.3 Aug 2020
