Waterway Executive Wet End 48 Frame | 2HP | 2" | 310-1890

The Waterway 310-1890 Executive Wet End is designed for 2 HP motors in a 48-frame setup and uses 2 inch suction and discharge ports to deliver strong flow and pressure for larger spa and pool systems. Its pre-assembled layout includes the volute, impeller, wear ring, mechanical seal, suction cover, O-rings and drain plug, giving the assembly the same alignment and performance expected from the original genuine Executive-series design. The discharge can be rotated in 90-degree increments to match different plumbing orientations, making it practical for pump rebuilds or retrofits. Built to withstand chemical exposure and thermal cycling, this wet end offers dependable long-term service when replacing worn Executive units.
