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.
Valves or Plunger?
Two different symptoms, two different kits.
Pressure that pulses or will not build, with no external leak — the valves are not seating. This kit.
Water weeping from the pump body, or pressure that falls away under load — the plunger seals are gone. Use the Pumptec Kit A Plunger and Seals, 205V and 207V (10055).
On a pump that has done real hours, do both while it is apart. Valve orientation matters: follow the manifold label when refitting.
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.

Frequently Asked Questions
Is this the same Kit B as the 112T?
No. The 112, 113, 217, 350 and 360 series use Kit B 10004.
Which way do the valves go in?
Follow the IN and OUT orientation on the pump manifold label.
Pressure pulses but nothing leaks. Is it this kit?
Yes. That pattern points to valves not seating.
What We See in the Field
