7.3.3 Sealing Head
The sealing head should be inspected for scratches and wear on two
surfaces:
• HP seal contact surface
• Inlet HP check valve poppet contact surface
In addition, the sealing head inlet water groove should be examined for
cracking.
1. Inspect the inlet poppet sealing surface of the sealing head for pits,
scratches, or jetting erosion. Refinishing the seal head inlet poppet face
is mandatory when rebuilding the sealing head. Using a piece of plate
glass (not window glass) on a sturdy table, place a piece of 400 grit
wet/dry sandpaper atop the plate of glass which provides the absolutely
flat surface necessary for the polishing process. Using even, deliberate
strokes, polish the sealing head until smooth. Rotate the head about 10-
15 degrees every stroke. Be careful not to tilt or tip the head while
polishing it as to not scrape the part.
2. When the sealing head is flat and smooth, perform a final polish with
600 grit wet/dry sandpaper. A mirror finish is required. KMT Waterjet
offers a refinishing service.
