The IMO D6 pump is a positive constant displacement rotary three screw pump designed for
high pressure and high flow in applications for lubricating oils, hydrauIic fluids, fuel oils and
fluids with similar lubricating properties.
The IMO pump has only three moving parts - three intermeshing screws. It has no gears,
valves or vanes. It is the simplicity of the design that makes it so reliable and efficient. The
exactIy calculated curve of the screw thread eliminates puIsation and ensures quiet running.
The IMO pump is self-priming even under high suction lift conditions.
