What is Eccentric Disk Pump & How Does it Works? (2022 Guideline)
Eccentric disc pumps are made up of a cylinder and a pumping element that are positioned on an eccentric shaft. As the eccentric bearing moves the disc, two different pumping chambers increase and decrease in volume, creating both suction and discharge pressures as the chambers move in pairs 180 degrees apart. Generally, the pumping element produces chambers within the cylinder as the eccentric shaft rotates, which grows in size at the intake port, sucking fluid into the pumping chamber. The fluid is transferred to the discharge port, which reduces the size of the pumping chamber. The fluid is squeezed out into the discharge piping as a result of this action. This disc action ensures continuous and regular fluid flow without worrying about cavitation, pulsation, slide, or shear. Linquip is proud to represent a number of companies that manufacture high-quality eccentric disk pumps from across the world. An eccentric disc pump's sealless operation is another design benefit. Without mechanical seals, leaks are minimized, and maintenance time is reduced. Its ability to clean in place eliminates the need for disassembly for maintenance and cleaning. Finally, there are no magnets because the gear reduction unit or motor is directly connected to the pump. Because of its unique design, eccentric disc pump technology was created primarily for the oil and chemical industries, allowing it to move viscous, non-lubricating, volatile, and fragile products without risk of shearing. This involves the safe handling of emulsions, inks, adhesives, and resins in the chemical industry, as well as crude oil, waste oils, and a variety of traditional and alternative fuels in the petroleum industry. Molasses, cooking oil, and cocoa butter, to name a few, have all been handled using these pumps.

Andre Petit, a French engineer, invented the eccentric disc pumping technology. He was working in gold mines when he took a closer look at the current methods for conveying water and other liquids out of the mine and decided to improve them, which he did in 1906 with the creation of eccentric disc technology for pump operations. We've attempted to provide an outline of the essentials of an eccentric disk pump, as well as how it operates, in this article.
Eccentric Disc Pump
An eccentric disc pump has a disc strategically placed inside a pump cylinder that is powered by an eccentric bearing on the pump shaft, as the name implies. The pump creates four separate chambers that are 180 degrees apart and whose volumes can rise or decrease as the disc rotates. Additionally, when the four chambers move in pairs, the suction and discharge pressures rise. Without worrying about cavitation, pulsation, slip, or shear, this disc operation assures consistent and regular fluid flow.
Another design advantage of an eccentric disc pump is its sealless functioning. Leaks are minimized, and maintenance time is decreased without mechanical seals. Its ability to clean in place allows for maintenance and cleaning without disassembly. Finally, the gear reduction unit or motor is directly attached to the pump, eliminating the need for magnets.

How Does An Eccentric Disk Pump Work?
The eccentric disc pump works on the principle of rotating a disc with an off-center shaft to produce an eccentric movement against hermetically sealed metal bellows or rubber boot. The rubber boot or bellows does not spin but rather flexes, obviating the requirement for seals in the pump drive, making it ideal for food manufacturing and processing that demands sanitary and hygienic conditions. Chemicals, food, pharmaceuticals, cosmetics, and petrochemicals benefit from eccentric disc technologies.
Advantages of A Eccentric Disk Pump
The advantages of eccentric movement technology over other pumps are numerous. Because there are no mechanical seals, they are leak-free and require less maintenance. Magnets are not required because motors with gear reducers are intimately connected to each pump. These pumps can be cleaned in place (CIP), which means they may be cleaned and flushed without disassembling them. The stainless steel variants have EHEDG and 3A certifications for sanitary uses. The eccentric disc pumps efficiently handle fluids while gently handling them.
The eccentric disc's rotational motion provides for a consistent and regular flow rate with very little shear, allowing them to handle shear-sensitive liquids such as food, cosmetics, emulsions, sauces, yogurt, and many more.
In general, the following benefits can be mentioned for this pump:
- There are no mechanical seals on the shaft, hence there are no leaks.
- The ability to dry prime without causing damage.
- Allows the pump to self-prime by providing high suction and discharge pressures.
- Excellent shear-sensitive fluid handling ability.
- Ability to clean in place for easier maintenance and service.
- Pumping action that is more efficient and safer.
- Product recovery is higher as compared to other varieties.

Application of Eccentric Disk Pumps
Eccentric disc pump technology was designed specifically for the oil and chemical industries because of its unique design, which allows it to transport viscous, non-lubricating, volatile, and fragile materials without risk of shearing. In the chemical business, this covers the safe handling of emulsions, inks, adhesives, and resins; in the petroleum markets, it includes crude oil, waste oils, and many different forms of traditional and alternative fuels. Food manufacturers began using these pumps to handle molasses, cooking oil, and cocoa butter, to mention a few.
