IMO PUMPS

Three-screw pumps are the largest class of multiple screw pumps in service today. They are commonly used for machinery lubrication hydraulic elevators fuel oil transport and burner service powering hydraulic machinery. They are also used in refinery processes for high-temperature viscous products such as asphalt, vacuum tower bottoms and residual fuel oils. Three screw pumps also find extensive use in crude oil pipeline service as well as gathering, boosting and loading of barges and ships. They are common in engine rooms on most of the world's commercial marine vessels and many combat ships. Flow rates are available from 1 to 3300 GPM (4 to 13,250 L/M) or for operating pressures to 4500 PSIG (310 BAR).Subject to material selection limitations, three screw pumps are also used for polymer pumping in the manufacture of synthetic fibers such as nylon and lycra. Designs are now available in sealless configurations such as magnetic drives and canned arrangements. The magnetic drive screw pump is used extensively for pumping isocyanate, a plastic component that is an extremely difficult fluid to seal using conventional technology. Pumps are also now available in sealless canned configurations. Three screw pumps are renowned for their low noise levels, high reliability and long life. Three screw pumps are capable of water injection services (Tritec) as well as high-pressure coolant service for machine tools (Emtec).
