The 2421643 Elite 4500 Service Pump Assembly is a factory-assembled replacement pump unit designed for use in Elite 5500 series equipment. Despite its "4500" designation, this service assembly is fully compatible with Elite 5500 models and contains all internal components pre-installed and ready for installation, including pistons, packings, inlet and outlet valves, and seals.
Over time, pump components wear from normal use, abrasive materials, and continuous operation. Symptoms such as pressure loss, surging, poor priming, or external leaks indicate the need for pump service. This complete service pump assembly eliminates the need for individual component replacement and bench rebuilding, reducing downtime and ensuring reliable performance.
