Processing fish, lard and vegetable oils is the main business of Olvea Group in the small town of Fecamp, close to the English Channel in the northwest of France. These oils that were arriving at the plant were to be used for specific end products. This included the creation of cosmetics, pharmaceuticals, human food and animal feed, as well as various technical uses, such as the building of lasers and as lubricants for leather and metal work.
These processes require strict purity for the oils as they move from transport truck to storage tank to 330-gallon intermediate bulk containers (IBC) and 50-gallon drums, meaning that no cross-contamination could be tolerated. Additionally, because of the high value of the oils, any products that were left in the transport truck, storage tank or hoses after the transfer process was completed would essentially be lost during the necessary cleaning process.
Francois Daudruy, technical director of the company, tested the A Series model for the transfer of the oils from storage tanks to shipping containers, and P Series Vane Pumps for the unloading of transport trucks.
Mouvex A Series pumps operate via the “eccentric movement principle”. These pumps are driven by an eccentric bearing that is installed on the pump shaft. This creates four distinct pumping chambers that increase and decrease in volume as the disc is rotated by the eccentric bearing, producing both suction and discharge pressures as the chambers move in pairs that are 180 degrees apart. This ingenious method of operation ensures that the fluid passes through the pump at a constant and regular flow rate.
