Mouvex® Eccentric Disc Pump Technology

Eccentric movement technology is at the core of Mouvex®. Mouvex founder Andre Petit identified the challenges that gear and lobe pump users were facing in optimizing their process and invented the eccentric disc pump as a result. Petit specifically placed a disc inside the pump cylinder so the eccentric disc would be more user-friendly. This disc is driven by an eccentric bearing that is installed on the pump shaft, thus creating four distinct pumping chambers that increase and decrease in volume as the disc is rotated by the eccentric bearing. The four chambers produce both suction and discharge pressures as the chambers move in pairs that are 180 degrees apart. This ensures that the fluid passes through the pump at a constant and regular flow rate.

How It Works

Eccentric disc pumps consist of a cylinder and pumping element mounted on an eccentric shaft. As the eccentric shaft is rotated, the pumping element forms chambers within the cylinder, which increase in size at the intake port, drawing fluid into the pumping chamber. The fluid is transported to the discharge port where the pumping chamber size is decreased. This action squeezes the fluid out into the discharge piping.
