Description

The AR (Annovi Reverberi) Kit 2544 is a professional-grade ceramic piston replacement set designed for high-performance pumps with 15mm plungers. This kit is a critical component for “dry-end” pump maintenance, specifically for the XM, XMA, XMV, and RRV series.

Ceramic pistons are engineered for extreme hardness and heat resistance, but they can crack or become “scored” over time due to thermal shock (running the pump dry) or debris in the water supply. Replacing worn pistons with this kit restores the smooth surface necessary for your water seals to function correctly.
