Allis-Chalmers 8100 Series Horizontal Split Case Centrifugal Pump, Size 6x8-12, 13.01" Impeller

The Allis-Chalmers 8100 Series is a robust, single-stage, double-suction horizontal split case centrifugal pump designed for high-flow applications in water supply, irrigation, municipal services, fire protection, and industrial processes. This model, sized 6x8-12 with a 13.01" impeller, offers efficient performance with flow rates up to 2,500 GPM and heads up to 200 feet, making it ideal for transferring large volumes of water or similar low-viscosity fluids. Key features include an axially split casing for easy maintenance without disconnecting piping, bronze-fitted construction for durability, and mechanical seals for reliable operation. Advantages over similar products include superior hydraulic efficiency, reduced downtime due to accessible internals, and compatibility with various drive options like electric motors or engines. Benefits encompass high reliability in continuous duty, energy savings from optimized impeller design, and versatility in handling clean to slightly contaminated liquids. Drawbacks may include its larger footprint requiring more installation space and higher initial cost compared to end-suction pumps. Based on image analysis, this unit appears used or refurbished, with visible wear and rust in the interior but intact exterior paint, suitable for remanufacturing or direct reuse in demanding environments.
