Haight Pump 30U-VMS Viton Mechanical Seal Internal Gear Pump
The Haight Pump 30U-VMS is a rugged internal gear pump engineered for dependable industrial fluid transfer and lubrication applications. Built with durable ductile iron construction and equipped with a Viton mechanical seal, this pump is designed to handle demanding operating environments involving oils, petroleum products, lubricants, inks, detergents, and other industrial fluids. Its compact gear-within-a-gear design delivers smooth flow, reduced wear, and quiet operation at standard motor speeds.
Designed for long service life and simplified maintenance, the 30U-VMS offers self-priming capability and reversible operation without requiring piping modifications. The pump’s steel shaft and gear assembly provide excellent durability, while the Viton mechanical seal improves chemical resistance and sealing reliability in challenging applications. This model is supplied as a pump end only and does not include a motor or relief valve.
Ideal for industrial facilities, transportation systems, lubrication equipment, hydraulic systems, and manufacturing operations, the Haight 30U-VMS combines efficient positive displacement pumping with proven American-made reliability. Haight Pumps have been manufacturing internal gear pumps in the United States since 1932.
