Swimables Generic WhisperFlo Style Pump Wet End, 0.5 to 2 HP, with High Temp Unions

The Swimables SW-21-149 is an aftermarket wet end built in the WhisperFlo style for pumps from 0.5 to 2 HP. It ships with high temperature unions, so it connects to existing plumbing without hunting for separate fittings.

Why replace the wet end

When a WhisperFlo housing cracks, the seal plate is scored, or the volute has worn past the point of a seal and impeller job, a new wet end brings the pump back while reusing a motor that still has life in it. That is far cheaper than a complete pump.

Before you order

This is a generic, not a Pentair part. It covers 0.5 through 2 HP; 3 HP motors need the larger Swimables wet end. No motor is included.
