With an unwavering commitment to delivering quality, certainty, and reliability, our expertise lies notably in the domain of eccentric disc pumps.

These high-performing pumps are renowned for their high suction and high volume efficiency, making them ideal for a range of applications in industries such as mining, heavy oil and gas, and manufacturing.

About Eccentric Disc Pump

French engineer Andre Petit invented the eccentric disc pump to overcome the challenges faced by gear and lobe pump users, featuring a disc driven by an eccentric bearing. He aimed to improve existing pump-design inefficiencies and transfer water or other liquids out from mines effectively. These pumps have become the perfect answer to issues like product wastage and high maintenance costs.

Eccentric Disc Pumps Features and Benefits

How Does an Eccentric Disc Pump Work?

An eccentric disc pump operates in a unique operating principle. As suggested by its name, it features a disc strategically placed inside the pump cylinder and driven by an eccentric bearing installed on the pump shaft. The pumping element is mounted on an eccentric shaft and housed in a cylinder. As the shaft rotates, the pumping element creates chambers with the cylinder. This increases the size of the intake port and draws fluid inside the chamber.

This arrangement creates four distinct pumping chambers that move in pairs 180 degrees apart as the disc rotates. The four chambers produce suction and discharge pressures that increase with the increase and decrease in volume of these chambers.

As fluid passes through these chambers, a consistent and regular flow rate is maintained, creating a complete product “plug” out of the piping.

This process ensures a constant and regular fluid flow without concerns about cavitation, pulsation, slip, or shear, effectively forcing the fluid out of the discharge pipe.


Eccentric Disc Pumps are ideal for shear-sensitive products. Here are some applications where these pumps can be useful:

Food Industry

Cosmetics & Pharmaceutical Industries

Chemical Industry


When to Use Eccentric Disc Pumps

Eccentric Disc pumps are ideal for scenarios where the aim is to decrease costs associated with product recovery.

They minimise product waste and enhance cost-effectiveness due to their unique line-clearing and stripping abilities.

In process plants where pumps are employed for a variety of recurring yet sporadic operations, Eccentric Disc pumps prove to be highly efficient.

Their self-priming feature makes them an excellent choice in these environments.

Frequently Asked Questions (FAQs)

Eccentric Disc Pumps are more efficient than traditional lobe pumps. They handle products gently, reducing damage to delicate items like sauces. They ensure consistent flow rates and operate without mechanical seals, minimising leaks and maintenance time. Eccentric Disc Pumps are up to 30% more efficient, increasing productivity and reliability while decreasing costs, making them an excellent alternative to lobe pumps.

The principle of an Eccentric Disc Pump is based on the eccentric movement of a disc inside the pump cylinder. As the shaft rotates, it forms chambers that draw and push fluid in and out. This unique mechanism creates a constant, regular flow rate without pulsing, cavitation, slip or shear, enhancing efficiency and reducing damage to delicate products.

Disc Pumps, or Eccentric Disc Pumps, are positive displacement pumps ideal for handling viscous, abrasive fluids at low flow rates. They operate by trapping and displacing liquid through an eccentric disc. Centrifugal Pumps, on the other hand, are rotodynamic pumps suited for high flow rate applications with clean, low viscosity fluids. They work by imparting energy to the fluid via a rotating impeller.

Yes, their clean-in-place capability ensures cleanliness is easily maintained without any dismantlement.
