ring, Retaining, External, 35.2IDx1.75mm, Rietschle, V-VCA-VCE, Part# 622051 – vacstellar

This external retaining ring is a small metal clip that does a big job on your Rietschle pump. It fits the V-VCA and VCE series – models like the VCA25, VCE25, VCA40, VCE40, VCA60, VCE60, VCAH100, and VCEH100.

These pumps run every day in labs, print shops, and small production lines. They have spinning shafts and bearings inside that need to stay exactly where they belong.

The retaining ring snaps into a groove to lock things in place. Without it or if the old one is bent or worn, parts can shift, make noise, or even come loose over time.

This ring is made to match the original Rietschle specs – 35.2 mm inner diameter and 1.75 mm thick. It pops right in during a service or rebuild. You usually use pliers to spread it a bit, slide it into the groove, and let it snap back tight.

Techs often replace these when they open the pump for bearings or a major check. It’s quick and keeps everything secure so the pump runs smooth and lasts longer.
