IMO 3E: Performance: 4-375 L/min. Max 10 Bar.

Series 3E pumps are provided for differential pressures to 150 PSIG (10 Bar) and flow rates to 100 GPM (375 L/M). Mountings include foot or flange. Casing materials are either cast iron or steel. These three screw pumps are used for fuel oil transfer and burner services, machinery lubrication and other industrial pumping applications. Units without shaft seals can operate at very high speeds on lubrication services when drive by the machine being lubricated. 3E series pumps are also available in canned motor/pump configurations up to 6 HP (4.5 kW).

IMO 3G: Performance 4 – 208L/min. Max 17 Bar.

Series 3G pumps are provided for differential pressures to 250 PSIG (17.2 Bar) and flow rates to 55 GPM (208 L/M). Mountings include foot or flange. Casing materials are either cast iron or steel. These three screw pumps are used for distillate fuel oil transfer and burner services, machinery lubrication and other industrial pumping applications. Most sizes are available with a tamper resistant built-in pressure relief valve for protection of the pump from momentary pressure overloads.

IMO 3D: Performance: 20-1500L/min. Max 35 Bar.

The 3D series pumps is a general purpose design suitable for many applications including lubrication, fuel transport and burner service, low pressure hydraulic applications and hydraulic elevator service. Pump shaft is generously sized to allow belt drive if desired (mechanical seal versions only). This series is also available in magnetic drive configurations.

IMO 6D: Performance: 20-1500L/min. Max 100 Bar.

Series 6D is a medium pressure pump line finding extensive use on fuel oil burners, high pressure trunion lubrication for ball mills, crude oil pipeline service and non-cyclic hydraulic applications.

Other IMO triple screw pump models are below.

IMO produce a very large range of 3 screw pumps for a variety of applications. These pumps are so reliable that they are used commonly on board USA Navy vessels. These pump can also reliably pump crude oil vast distances at high flow rates and pressures.
