SEE REPLACEMENT PART: OBSOLETE

Pentair/Purex IntelliFlo/Whisperflo 3.0 HP Diffuser (72928) is a replacement pump component intended for the compatible pump model or horsepower range noted in the product name. Pump internals such as diffusers, impeller hardware, volutes, and related parts help direct water efficiently through the wet end and maintain proper hydraulic performance. This item is useful when the original component is cracked, warped, worn, noisy, or damaged during pump service. Replacing the correct internal part can help restore flow, reduce turbulence, and prevent additional wear on surrounding pump components.

Before ordering, compare the exact model, horsepower, frame/application details, and part number with the existing pump or parts diagram. Similar pump families often use different internal parts, so confirmation is important before disassembly or installation.
