KMT Waterjet Streamline SL-VI 100i Intensifier Pump

The KMT Waterjet Streamline SL-VI 100i is a high-pressure intensifier pump system designed as the pressurization backbone for industrial waterjet and abrasive waterjet cutting machines. KMT Waterjet Systems is the world's leading manufacturer of high-pressure waterjet intensifier pumps and supplies OEM pump systems to virtually every major waterjet cutting machine manufacturer — including Flow International, OMAX, Jet Edge, and WARDJet. The SL-VI 100i is a 100 HP pump in the Streamline Series VI generation, designed to deliver 60,000 psi continuous operating pressure with improved energy efficiency, longer seal life, and reduced noise compared to previous-generation intensifier designs.

The intensifier pump is the most critical component in an abrasive waterjet cutting system. It takes standard shop water and pressurizes it to 60,000 psi (4,137 bar) through a hydraulically driven intensifier cylinder — a large hydraulic piston on one side compresses a small water piston on the other, multiplying pressure by the ratio of piston areas. The SL-VI's design includes dual intensifier cylinders operating in sequence to produce a continuous, pulsation-dampened high-pressure water stream. KMT's proprietary seal and check valve design extends maintenance intervals and reduces the frequency of high-pressure seal replacement, which is the primary wear-related maintenance item in intensifier operation.

The Streamline SL-VI series incorporates several energy efficiency advances over prior generations. Variable frequency drive (VFD) on the hydraulic drive motor reduces power consumption during non-cutting periods and soft-starts the hydraulic system, reducing mechanical stress at startup. KMT reports 15–20% energy savings versus older constant-speed designs. The SL-VI 100i also features an integrated water treatment bypass, diagnostics display, and remote monitoring connectivity that allows operators and service providers to track pump health parameters (pressure, temperature, flow, cycle count) without opening the pump enclosure.

As an OEM and aftermarket pump supplier, KMT occupies a unique position in the waterjet industry — the SL-VI 100i can be used as a new cutting system pump (often supplied as part of a complete waterjet system from a machine builder), or as a direct replacement for worn-out pumps on any brand of waterjet cutting machine. Shops running older Flow, OMAX, Bystronic, or other waterjet cutting tables whose original pumps have reached end-of-life can install the SL-VI as a performance upgrade. KMT's global service and parts network provides the widest consumables availability of any waterjet pump manufacturer.
