Question by: Daryl A on Jun 13, 2025, 4:58 PM
what all does this seal kit cover, is it just for the S1 33/39 or does it work across different pump sizes too?
Answer by: Customer Support on Jun 14, 2025, 9:37 PM
Eaton lists this kit as available in all configurations and sizes, so it's not locked to a single variant. The kit itself is a PV sealing overhaul kit, meaning it covers the sealing components you'd need when doing a full rebuild on the pump rather than just spot repairs. If your unit is an S1 33/39, this is the one you'd be pulling for that job.

Will this kit work on any Eaton Char-Lynn piston pump? Gotta make sure before I order.

This seal kit is designed for Eaton Char-Lynn piston pumps and is available in all configurations and sizes. To ensure compatibility, verify that your pump model matches the kit's specifications.

got a piston pump that needs fresh seals. what exactly comes in this kit
Answer by: Customer Support on Oct 4, 2025, 6:55 AM
Inside the package you get a PV sealing overhaul kit meant for piston pump accessory service, so it is focused on replacing the sealing components rather than being a full pump rebuild set.
