Pentair 072927Z Diffuser Assembly

Part Number: 072927Z

Description

This diffuser assembly is an OEM replacement part for Pentair WhisperFlo® and IntelliFlo® pool pumps (½ HP to 2½ HP). It helps maintain proper water flow by guiding the fluid into the volute, enhancing pump efficiency and extending service life.

Compatibility & Fitment

  • Designed for use with Pentair WhisperFlo WFE series pumps (WFE-2 to WFE-8, ¾ HP to 2½ HP). 
  • Also compatible with IntelliFlo® i1/i2 variable speed pumps manufactured after April 2016.
  • Use when the original diffuser is worn, cracked or showing signs of flow instability or high current draw in the pump system. 

Features & Specifications

  • High-quality thermoplastic construction engineered for pool water environments.
  • Fits ½ HP to 2½ HP pump frame sizes, ensuring broad application range.
  • Maintains OEM hydraulic performance when replaced correctly.
  • UPC: 788379886905. 

Installation Notes

Turn off power and lock out the pump circuit. Remove the pump volute cover and motor bracket. Remove the impeller and old diffuser, inspect for excess wear or damage. Insert the 072927Z diffuser assembly into the pump housing, ensure correct seating and rotation clearance. Reassemble the motor bracket and cover, restore power, and verify correct flow and absence of vibration.

Maintenance Tip

During annual service, inspect the diffuser for cracks, excessive wear or erosion. Replacing the diffuser at first signs of hydraulic degradation helps prevent pump over-current, overheating, and premature failure.
