Multi screw pumps belong to the group of self-priming, valve-less rotating positive displacement pumps. Due to their design they are specially suitable for lubricating media. Although they are compact in design they can reach high flow rates and high pressure. Some designs are even suitable for non-lubricating or solid loaden fluids. Low to high lubricant media low / medium to high viscosity media aggressive media abrasive media corrosive media shear-sensitive media
