Description

The AR (Annovi Reverberi) Kit 2873 is the dedicated oil seal kit for the SXW and SXWA series industrial pumps. While the water seals (packings) handle the high-pressure manifold side, these oil seals are the critical barrier for the crankcase, ensuring that the pump’s internal lubrication stays in and contaminants stay out.

Because the SXW series is designed for high-flow, high-pressure industrial use (often 5–10 GPM), the crankcase generates significant heat. These seals are built to maintain their shape and sealing tension under those demanding conditions.
