Haight 54U-VMS DIU Series Internal Gear Pump with Viton Seal
The Haight Pump 54U-VMS is a heavy-duty internal gear pump designed for industrial-grade fluid transfer applications requiring reliability, durability, and high performance. Built with a ductile iron housing and equipped with a Viton mechanical seal, this model is engineered to handle demanding environments where temperature resistance and chemical compatibility are essential. It is part of the trusted DIU Series 54 GPM positive displacement pump lineup, widely used across multiple industrial sectors.
With a maximum flow capacity of 54 GPM and pressure ratings up to 250 psi, the 54U-VMS is ideal for continuous-duty operations. Its internal gear design ensures smooth, low-pulsation flow, while supporting self-priming capability and bidirectional operation. The pump is commonly used in systems where consistent lubrication, fluid transfer, or process handling is required.
This model is supplied as a pump end only (no motor, no relief valve), allowing flexible integration into existing industrial setups. The Viton seal option enhances resistance to high temperatures and aggressive fluids, making it suitable for chemical processing, machinery lubrication, and fuel-handling systems.
