IMO 3 Screw Pumps - 3E Series

IMO 3 Screw Pumps – 3E Series

MFG in Columbia, KY USA

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).

THREE-SCREW PUMPS

The Superior Pumping Technology

Triple Screw Pump (3 Screw) Discover our three-screw pumps – the clear choice for superior performance and versatility. The unique design with three interlocking spindles provides an extremely efficient and smooth flow, resulting in impressive overall efficiency.

In addition to excellent controllability, the self-priming pumps offer minimal pulsation and remarkably quiet operation, even at high discharge pressures.

Our three-screw pumps are true all-rounders, capable of handling a wide range of fluids of varying viscosities – from low-viscosity fluids to highly viscous substances. It’s robust design and the high wear resistance of the spindles ensure reliability and long life, making them the ideal choice for critical applications in a variety of industries.
