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. Some surface flaws can be polished and
repaired on site, while others must be polished using the reconditioning service
offered by KMT Waterjet.
