Haight 6EUR Internal Gear Pump with Viton Mechanical Seal & Relief Valve
The Haight 6EUR internal gear pump is a compact, heavy-duty positive displacement pump engineered for reliable industrial performance. Built with a rugged ductile iron housing, steel gears, and a Viton mechanical seal, it is designed to handle demanding fluid transfer applications with consistent efficiency. The integrated built-in relief valve enhances operational safety by protecting system components from overpressure conditions.
With a nominal flow capacity of approximately 6 GPM, the 6EUR model is widely used across lubrication systems, hydraulic equipment, and general industrial fluid handling. Its internal “gear-within-a-gear” design provides smooth, quiet operation and strong suction performance, making it ideal for continuous-duty applications. The pump is also self-priming and supports reversible operation, adding flexibility for OEM and retrofit installations.
