7.3.5 Plunger
Plunger surfaces can become streaked with longitudinal scratches or flaws, the
surface can become discolored or dull in appearance, or the outboard end can
become smeared with stainless steel due to contact with the bore liner. If any
of these conditions become severe, the plunger HP seal and possibly the
hydraulic seals will leak excessively. Repair of plunger surface flaws usually
cannot be accomplished on site. KMT Watejet offers a plunger reconditioning
service.
