Haight Pump 5U Viton Lip Seal Gear Pump No Relief Valve (5 GPM)
The Haight Pump 5U Viton Lip Sl No R/V is a heavy-duty internal gear pump designed for industrial fluid transfer applications requiring reliability, precision, and high temperature resistance. Built with a rugged ductile iron housing and Viton lip seal technology, this pump delivers stable performance in demanding environments such as lubrication systems, hydraulic circuits, and industrial processing lines.
Rated for up to 5 GPM flow capacity and 250 PSI pressure, the 5U series pump is engineered for continuous-duty operation. Its self-priming positive displacement design ensures smooth, consistent flow even with high-viscosity fluids. The Viton seal enhances chemical resistance and high-temperature durability, making it ideal for oil-based and solvent-based applications.
This pump is commonly used as a pump end-only replacement unit and is compatible with multiple industrial configurations. Its reversible flow capability and modular design allow easy integration into OEM machinery and retrofit systems without major modifications.
