6D Series Three-Screw Pump

Series 6D IMO® pumps are intended for high pressure service on fluids with viscosity from 2cSt to 25,000ssu. Typical applications include crude oil pipeline service, fuel atomization for combustion gas turbine fuel injection, fluid power service on hydraulically operated machinery, gas sealing in centrifugal compressors and hydrostatic bearing support.

These pumps are hydraulically balanced in both the axial and radial directions, which eliminates bearing loads due to differential pressure. The single grease packed ball bearing is external to the liquid pumped and does not rely on the lubrication qualities of the pumped liquid. The single mechanical seal is exposed only to inlet pressure. Very low airborne noise levels are normal for IMO® three-screw positive displacement pumps as are high operating efficiencies and non-pulsating delivered flow.
