6D
Quick Overview
THREE SCREW PUMP
Rated Flow: 6 to 385 gpm (23 to 1457 l/min)Max Inlet Pressure: 50 to 75 PSIG (3 to 5 bar)
Max Outlet Pressure: 1000 to 1500 PSIG (70 to 103 bar)
Series 6D IMO pumps are intended for relatively high pressure service on petroleum or similar viscosity
liquids. Typical applications include crude oil pipeline service, fuel atomization for burning in a
steam boiler, fuel injection for combustion gas turbines, 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 discharge pressure. The single bearing is external to the liquid pumped and
does not rely on the lubricating 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 delivery of flow.
