Full Product Description +
The Swimables Impeller (SW-21-302) is a replacement pump impeller designed for Pentair pool pumps equipped with a 0.75 HP full-rated or 1 HP up-rated motor. The impeller is the primary hydraulic component responsible for generating water flow through the pump, filter, and circulation system.
When an impeller becomes worn, cracked, or obstructed, circulation efficiency drops even if the motor continues to run. Replacing the impeller restores proper flow, pressure, and overall system performance.
Why the Impeller Matters
The impeller converts motor rotation into usable water movement. Over time, debris ingestion, chemical exposure, heat, or shaft seal failure can damage the impeller vanes or hub.
Common symptoms of a failing impeller include:
-
Reduced circulation or weak return flow
-
Inadequate skimmer suction
-
Poor heater or cleaner performance
-
Pump running without producing expected pressure
Replacing the impeller is often the correct solution when flow loss is present but the motor is still operating.
Correct Sizing for 0.75 HP Full-Rated / 1 HP Up-Rated Motors
This impeller is engineered specifically for Pentair pumps using:
-
0.75 HP full-rated motors, or
-
1 HP up-rated motors
Matching the impeller to the correct motor rating is critical. Installing the wrong impeller can overload the motor, reduce hydraulic efficiency, or shorten pump lifespan.
Typically Replaced During Wet-End Service
Impeller replacement commonly occurs during service involving:
-
Shaft seal replacement
-
Diffuser inspection or replacement
-
Pump housing or wet-end repairs
Pump disassembly is required and installation should be performed by an experienced pool professional or knowledgeable DIY installer following proper safety procedures.
