INDUSTRY LEADING PRODUCTS, SERVICES AND SOLUTIONS

MFG in Columbia, KY USA

The 3G series pump is intended for use in lubrication, hydraulic and control oil services. 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.

THREE-SCREW PUMPS

The Superior Pumping Technology

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.

KEY BENEFITS
