Haight Pump 5U-VMS Viton Mechanical Seal Industrial Gear Pump (5 GPM)
The Haight Pump 5U-VMS is a rugged industrial-grade internal gear pump designed for demanding OEM and process applications. Built with a durable ductile iron housing and equipped with a Viton mechanical seal, this pump delivers reliable performance under high temperature and moderate pressure conditions. Its internal “gear within a gear” design ensures smooth, self-priming operation and efficient fluid transfer across a wide range of viscosities.
With a rated capacity of approximately 5 GPM, the 5U-VMS is widely used in lubrication systems, hydraulic equipment, machine tools, and industrial fluid handling systems. Its reversible operation capability and compact design make it suitable for direct motor mounting in tight industrial installations. The Viton seal enhances chemical resistance and high-temperature durability, extending service life in harsh environments.
Engineered for adaptability, the Haight 5U-VMS supports multiple industrial configurations and can be integrated into both new systems and replacement applications. Its field-serviceable seal system reduces downtime, making it a cost-effective solution for continuous-duty operations.
