Product Overview
Pumptec Kit B valve and seal repair kit, Pumptec part number 10004, with stainless steel valves and Buna O-rings.
Fitment
Pumptec lists 10004 for the 112, 113, 217, 350 and 360 (formerly 356) series. CCW has also listed it for:
- Force 250 (112T)

Important — Not for the 114T
The 114T uses a different valve kit, Pumptec 10014. The 205V and 207V use Kit B 10022 — see the Pumptec Kit B Valves and O-Rings, 205V and 207V (10022).
Rebuild Rather Than Replace
A plunger pump is a machined body with consumable seals, valves and O-rings inside it. Those consumables are what fail; the body outlives them many times over. A pump that has lost pressure or started pulsing is almost always telling you the valves or the seals are done, not that the pump is finished.
A rebuild kit and an hour on the bench is a fraction of the price of a pump, and it keeps the machine earning.
Buna O-Rings — Check Your Chemistry
This kit is supplied with Buna (nitrile) O-rings. Buna handles water and most general cleaning chemistry well and does not suit some solvents. Pumptec makes a Viton version for the 112T, part 10008. If you run solvent-based products through the pump, tell us before ordering.
Service Intervals
Pumptec recommends checking seals and valves at 500 hours, then every 500 hours until wear shows. Valves typically need changing at every seal change, and the pressure regulator should be serviced at the same time.
