OEM Replacement Packing Ring Set for Berkeley Impeller
The Pentair S13470 is the OEM replacement packing ring set for Berkeley pump impellers, sized at 2.75″ x 3.25″. If your Berkeley pump is showing signs of seal wear or leakage at the impeller, this is the correct service part to restore proper operation.
What It Does
The packing ring set forms a compression seal around the impeller shaft, preventing water from bypassing the impeller and maintaining pump efficiency. Replacing worn packing rings at the first sign of leakage helps protect the pump housing and shaft from accelerated wear.

Pro Tip
Before ordering, confirm the part number stamped or molded on your existing packing ring set matches S13470. Packing ring sets are dimensionally specific an incorrect size will not seal properly and may damage the pump housing. If your pump is open for service, inspect the impeller and shaft for scoring at the same time; a worn shaft can cause premature failure of a new packing ring set regardless of part quality.
