LOBE PUMP

Lobe Pump

Precision Fluid Handling for Viscous and Shear-Sensitive Applications

A lobe pump is a highly efficient type of positive displacement pump designed to transfer a wide variety of fluids — especially those with high viscosity, shear sensitivity, or abrasive properties. These pumps use two or more rotating lobes that turn in opposite directions within a casing, creating chambers that move the fluid from the inlet to the outlet with exceptional accuracy.

 How Lobe Pumps Work

Unlike centrifugal pumps, lobe pumps move a fixed volume of fluid per revolution, delivering a consistent and metered flow. As the lobes rotate, cavities form between the lobes and the pump casing, trapping fluid and gently transferring it through the system without contact between the lobes.

This non-contact design results in low shear force, making lobe pumps suitable for sensitive products that could be damaged by turbulence or aggressive movement.

 Key Benefits of Lobe Pumps

 Precise Flow Control

As a positive displacement device, a lobe pump delivers a constant flow regardless of pressure variations, ideal for applications demanding precise metering.

 Shear-Sensitive Fluid Handling

Thanks to their smooth, pulsation-free operation, lobe pumps are perfect for delicate fluids such as creams, sauces, or pharmaceutical compounds.

 Self-Priming Capability

Lobe pumps can operate without being fully flooded, making them ideal for systems where intermittent flow, empty lines, or variable fluid levels are common.

 Versatile Fluid Compatibility

From water-thin liquids to thick pastes and slurries, lobe pumps handle a wide range of fluid types, including corrosive, abrasive, and viscous materials.

 Common Applications

Lobe pumps are trusted in a variety of industries due to their reliable performance and gentle product handling:

• Food & Beverage: Transfer of syrups, honey, yogurt, sauces, jams, and other consumables requiring sanitary conditions.

• Pharmaceutical: Sterile fluid transfer in cleanroom environments where product integrity is crucial.

• Chemical Processing: Pumping of corrosive liquids, solvents, and viscous chemicals.

• Cosmetics & Personal Care: Handling of thick lotions, creams, gels, and emulsions in production lines.

Many lobe pumps are also CIP (Clean-in-Place) and SIP (Sterilize-in-Place) capable, complying with hygienic standards such as FDA, EHEDG, and 3A for use in regulated environments.
