SKU: 5528

The Udor UD-28 (Mfr. #6061.28) is an OEM seal kit with three 18mm plunger seals for Udor B-series and M-series pumps, covering models such as BC 13/20 S, BC 15/20 S, BC 18/20 S, BC 21/20 S, BD 4.0/20 S, BD 4.0/30 S, BD 5.0/30 S, BD 6.0/30 S, BKC 15/30 S, BKC 18/25 S, BKC 21/25 S, BKD 5.0/36 S, plus the gear-reduction BKC 15/30 GR, BKC 18/25 GR, BKC 21/25 GR, BC 18/20 GR, and BC 21/20 GR variants. These are the seals that ride against the ceramic plungers, so the kit restores pressure performance and stops head leakage on 18mm-plunger Udor pumps. SKU 5528.
