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

The Waterway 310-1890 Executive Wet End supports 2 HP 48-frame motors and uses 2 inch suction and discharge fittings to maintain the high flow required in larger spa and pool plumbing systems. Its pre-assembled components — including the volute, impeller, wear ring, mechanical seal, suction cover, O-rings and drain plug — follow the Executive wet end’s original OEM-style layout for dependable alignment and operation. The discharge can be rotated in 90-degree increments, making it easier to configure during rebuilds or when upgrading equipment. With materials built to handle chemical-treated water and repeated heat cycles, the 310-1890 offers a long-lasting replacement for Executive-series wet ends.

Highlights
