High Pressure Cylinder | .875 Plunger | 55K | SL-IV | HJ-05059712


The HJ-05059712 High Pressure Cylinder is a precision-engineered replacement cylinder designed for 55,000 PSI (3,800 bar) KMT waterjet intensifier pumps utilizing a 0.875-inch plunger. Manufactured from premium high-strength stainless steel, this critical high-pressure component provides exceptional durability, dimensional accuracy, and reliable sealing performance in demanding abrasive waterjet cutting applications.

Designed specifically for KMT SL-IV SSEC (Soft Seal End Cap) and NL-I intensifier units, the HJ-05059712 cylinder houses the high-pressure plunger and liner assembly while maintaining precise alignment during every intensification cycle. Its precision-machined bore minimizes wear, extends seal life, and helps maintain consistent operating pressure for maximum cutting efficiency.

Whether replacing a worn cylinder during scheduled maintenance or rebuilding an intensifier pump, the HJ-05059712 High Pressure Cylinder restores performance, improves system reliability, reduces downtime, and helps extend the service life of critical pump components.

Why Choose the HJ Waterjet High Pressure Cylinder HJ-05059712?

High-pressure cylinders are among the most important structural components inside an intensifier pump. A worn or damaged cylinder can cause premature seal failure, pressure loss, inconsistent cutting performance, and costly downtime. Replacing the cylinder with a precision-manufactured component restores proper pump geometry and ensures dependable ultra-high-pressure operation. The HJ-05059712 is engineered to deliver long service life, reliable sealing, and consistent performance in demanding industrial waterjet environments.
