Description

The AR (Annovi Reverberi) Kit 1855 is a specialized oil seal kit designed for the crankcase of the XRA and XMA “N” version pumps. While water seals (packings) handle the high-pressure side of the pump, these oil seals are the critical barrier on the “dry-end,” keeping the lubrication inside the crankcase and preventing environmental contaminants from entering.

The “N” version usually refers to a specific design revision or shaft configuration within the XR family, and using the correct oil seal is vital to maintaining the structural integrity of the internal bearings.
