Lobe Pumps

About Lobe Pumps


At Hunter Pumps, we bring over 25 years of experience supplying rotary lobe pumps. These are renowned for their reliable performance with low noise as a type of positive displacement pump. Lobe pumps have vast applications in sectors such as the food and beverage, cosmetic, and pharmaceutical industries.

Unlike external gear pumps, the lobes in these pumps do not make physical contact, allowing them to handle a variety of fluid flows without causing damage.

Our rotary lobe pumps are optimised for energy-efficient operation and feature a hygienic design, making them ideal for applications that require gentle handling of sensitive fluids and liquid-based products.

Hunter Pumps is committed to providing efficient, cost-effective solutions to meet customers’ diverse needs across multiple industries.

Industrial Lobe Pump Applications


Rotary lobe pumps are ideal for pumping pharmaceutical products. They are known for gently handling sensitive process fluids, even in strict hygienic conditions. Lobe pumps ensure the smooth and contamination-free movement of critical fluids like vaccines, serums, and other medicinal preparations.

Food Applications

Lobe pumps play a vital role in food processing applications, handling everything from thick pastes to delicate ingredients. Their ability to manage varying viscosities and temperatures makes them ideal for transferring products like sauces, jams, and dairy products.


In the beverage industry, lobe pumps transfer liquids ranging from high-viscosity syrups to low-viscosity alcoholic drinks. They offer a smooth, non-pulsating flow that ensures the quality and consistency of beverages.


For cosmetics applications, rotary lobe pumps are chosen for their gentle processing capabilities. They are excellent for transferring viscous products like creams, lotions, and gels without causing damage or altering their consistency.

Paints and Dyes

Lobe pumps handle paints and dyes efficiently, ensuring a smooth and consistent flow. Their robust design can handle the abrasive nature of these materials, making them a reliable choice for this industry.

Rubber & Adhesive

In the rubber and adhesive industry, lobe pumps are utilised for their ability to handle highly viscous and sticky materials. Their positive displacement design allows for an efficient and consistent transfer process.


Rotary lobe pumps ensure a smooth and consistent flow, which is crucial for maintaining the quality and texture of soaps and detergents. Their design prevents fluid shearing and degradation during transfer, leading to high efficiency and quality preservation of the end product.

Working Principle of Rotary Lobe Pumps

The operational mechanism of a lobe pump is designed to move a specific volume of fluid from the intake region to the discharge area. This is accomplished by the rotation of the key components, the lobes. These lobes are affixed to shafts that rest on bearings within an external synchroniser.

These shafts, armed with gears inside the synchroniser, convey the motion from the driving shaft to the secondary shaft. An essential feature is the synchronisation of the lobes, which ensures they do not touch each other during operation, minimising shaft deflection.

The process begins when the lobes rotate, creating a larger space between the lobes' teeth. This action induces a decrease in pressure on the suction side, leading to fluid ingress into the pump body. The fluid is channelled within the casing towards the pump's discharge side.

As the lobes continue their rotation, the space between them reduces, causing a rise in pressure on the discharge side. Consequently, this forces the fluid out of the pump body. This cyclic operation of the lobe pump enables fluid efficient and consistent displacement, making it an integral component in various industries.
