X-Series Waterblast Unit
APPENDIX A: TECHNICAL SPECIFICATIONS
General Unit Information
X-Series pumps come in a wide variety of
engines and waterblast output pressures. The
units can be trailer mounted or skid mounted.
The versatility of these Jetstream waterblast
units allows operators to modify the pump to
change to different operating pressure ranges
when necessary.
There are three basic ranges of pressure and are
usually referred to as 15K, 20K, and 40K. These
are abbreviated names to easily denote the
maximum operating pressure.
• The 15K pumps can operate up to 15,000
psi (1000 bar).
• The 20K pumps can operate up to 20,000
psi (1400 bar).
• The 40K pumps can operate up to 40,000
psi (2750 bar).
The three pressure ranges are achieved by
converting the part of the pump known as the
uid end. Each pressure range has its own
manifold, stufng boxes and plungers. The
materials and construction differs with the
pressure range. The various plunger diameters
control the discharge volume. The stufng
boxes are matched to the plungers in most
cases, but some are used with a range of
plunger sizes, so it is important to keep them
together. Instructions for converting to other
pressure ranges are detailed in “Pressure
Conversion” on page 43. Contact Jetstream
Customer Service or Engineering with any
questions.
