Eccentric Disc Technology

Eccentric Disc Technology is a specialised pumping mechanism used primarily in positive displacement pumps, offering high precision, clean operation, and gentle product handling. It's commonly found in hygienic industries such as food and beverage, pharmaceutical, and cosmetics. At its core, eccentric disc technology uses a disc that moves in an eccentric (off-centre) circular motion within a cylindrical pumping chamber. As the disc moves, it creates sealed cavities that draw in, trap, and displace fluid from the inlet to the outlet.

Eccentric disc pumps are often associated with brands like Mouvex, known for their innovation in clean and leak-free fluid transfer.

Operating Principles

Eccentric Disc Pumps are precision-engineered for sensitive applications with potential shear and leakage concerns.

An eccentric disc pump consists of a cylinder and a pumping element mounted on an eccentric shaft. As the eccentric shaft rotates, the pumping element creates chambers with the cylinder. This has the effect of increasing the size of the intake port and drawing fluid into the pumping chamber. The fluid is transported to the discharge port where the size of the pumping chamber decreases. The action squeezes the fluid out into the discharge pipe work. However, its action is far more sensitive making it ideally suited to applications where shear and potential leakage are major issues.
