About This Item
The Pentair Impeller Screw Washer (072172Z) is the OEM replacement hardware washer that secures the impeller screw on WhisperFloXF, WhisperFloXF VS, IntelliFlo VS, IntelliFlo VSF, Max-E-ProXF VS, and EQ Series Commercial Plastic pumps built after October 7, 2019.
IMPORTANT: BUILD-DATE APPLICABILITY
This washer is applicable to pumps manufactured after 10/7/2019 only. Confirm your pump's manufacture date or compare against the original washer before ordering.
IMPORTANT: QUANTITY VARIES BY MODEL
Most compatible pumps require 1 washer per impeller screw. The EQ Series Commercial Plastic Pump requires 4 washers per pump. Verify the quantity needed for your specific model before ordering.
This washer seats beneath the impeller screw head, distributing clamping load evenly across the screw and pump shaft face. Proper seating keeps the impeller screw torqued to spec and prevents loosening from pump vibration over time.

Poolaroo Pro Tip
Because this washer applies only to pumps built after 10/7/2019, check your pump's manufacture date or compare the old washer's profile before ordering — installing this revision on an earlier-production pump can result in improper impeller screw seating. If you're servicing an EQ Series Commercial Plastic Pump, order enough washers for all four impeller screw positions; this model requires four washers per pump, while every other compatible model uses just one.
