High Pressure Cylinder Assembly | SL-V Classic Version I | 0.875” Plunger |3,500 Bar / 52,000 PSI | HJ-72120023


The HJ-72120023 High Pressure Cylinder Assembly is a precision-engineered replacement cylinder designed for KMT Streamline SL-V Classic Version I waterjet intensifier pumps operating at 3,500 bar (52,000 PSI). Manufactured from premium high-strength alloy steel and precision machined to exact tolerances, this HJ-72120023 cylinder provides exceptional durability, pressure containment, and long service life in demanding industrial waterjet cutting applications.

Designed for 0.875-inch (7/8") plunger systems, the HJ-72120023 cylinder forms the primary high-pressure chamber where hydraulic energy is converted into ultra-high-pressure water. Its precision-honed internal bore minimizes seal wear while maximizing sealing efficiency, resulting in improved pump performance, reduced maintenance intervals, and consistent cutting pressure.

This HJ-72120023 cylinder is a direct replacement for KMT Part Number 20414862 and 72120023 used on KMT Streamline SL-V Classic Version I 50 HP intensifier pumps operating at 52,000 PSI (3,500 bar).
