Description

The AR (Annovi Reverberi) Kit 2543 is a premium ceramic piston (plunger) replacement set designed for the heavy-duty XW and XWA series pumps featuring 22mm diameters. These pumps are the “workhorses” of the AR line, often pushing 5 to 10 GPM in industrial and truck-mount applications.

Because 22mm pumps move such a high volume of water, the pistons are subject to significant thermal stress. Kit 2543 provides the high-hardness ceramic sleeves and mounting hardware necessary to restore a mirror-smooth surface for your water seals.
