SuperPro Replacement WhisperFlo 1 HP Pump Impeller 073128 In stock$8499
Quick overview
- Replaces 073128 The aftermarket equivalent of the 073128 WhisperFlo impeller.
- Sized for 1 HP Matched to the 1 HP WhisperFlo. Impellers are horsepower specific and are not interchangeable between sizes.
- SuperPro 25305-128-000 Ordered by the SuperPro part number.
- Restores lost flow A worn or blocked impeller shows up as weak returns and a low filter pressure reading.
- Check the diffuser too Impeller wear and diffuser wear usually arrive together, and a new impeller in a worn diffuser gives back only part of the flow.
- Replace the shaft seal Getting to the impeller means opening the seal, so plan on a new mechanical seal in the same job.

Product details
SuperPro 25305-128-000 is a replacement impeller for the 1 HP WhisperFlo pump, sold as the aftermarket equivalent of impeller 073128.
Match the horsepower
Impellers are specific to the horsepower of the pump. The vane shape and passage size are what set the flow curve, so an impeller from a different size WhisperFlo will not give the performance the pump was designed for, even where it physically threads on. Read the number off the old impeller, or off the pump label, before ordering.
The symptoms it fixes
An impeller that is worn or partly blocked produces weak returns and a low pressure reading at the filter, which is the reverse of what a dirty filter does. Debris packed into the vanes gives the same result and is worth checking before ordering anything. A rattling wet end usually means the vanes are damaged.
Plan the whole job
Reaching the impeller means opening the seal plate, and the mechanical shaft seal should not be reused once it is disturbed. Look at the diffuser while the pump is apart: it wears alongside the impeller, and replacing one without the other returns only part of the lost flow.
