Overview
The KMT Streamline Pro+ is KMT Waterjet Systems' flagship intensifier pump series, operating at 60,000 PSI (4,137 bar) with power ratings from 30 HP to 125 HP. Unlike Flow's and OMAX's vertically integrated waterjet machines, KMT Waterjet is primarily a pump and component manufacturer — the Streamline Pro+ is the high-pressure pump system that powers waterjet cutting tables from WardJet, Techni Waterjet, PTV, and dozens of other OEMs worldwide. Understanding KMT's pump technology is essential for anyone evaluating non-Flow, non-OMAX waterjet systems, as KMT claims the largest installed base of high-pressure waterjet pumps globally.
The Streamline Pro+ uses KMT's proven dual-intensifier design, where two high-pressure cylinders alternate pumping strokes through a hydraulic drive circuit. This alternating action delivers a relatively smooth, continuous pressure output at the cutting head, which is important for edge quality on demanding materials. KMT's Pro+ series incorporates several refinements over the standard Streamline SL-V line: improved seal geometry for longer service life, enhanced hydraulic circuit design for reduced pressure pulsation, electronic pressure regulation for tighter process control, and KMT's IDEKO monitoring system for remote diagnostics and predictive maintenance.
The Pro+ is available in single-intensifier configurations (30-50 HP) and dual-intensifier configurations (50-125 HP). The dual-intensifier units deliver higher flow rates, enabling larger orifice sizes that improve cutting speed on thick materials. KMT also offers a 90,000 PSI variant (SL-V 90 series) for shops requiring ultra-high pressure capability, though the standard Pro+ at 60,000 PSI covers the majority of commercial waterjet applications. Spare parts, seals, and service are available globally through KMT's dealer network — a key advantage for shops in regions where Flow or OMAX service is limited.
The Streamline Pro+ pump unit is typically priced from $40,000 for the 30 HP single-intensifier to $120,000+ for the 125 HP dual-intensifier. As a component rather than a complete machine, pricing is always in the context of the cutting table it will power. Shops evaluating a WardJet, Techni, or similar non-Flow/OMAX machine should factor the Pro+ pump into total system cost, and should compare Pro+ service costs against OMAX's EnduroMAX direct-drive operating costs.

Strengths & Limitations
Strengths
- Largest global installed base of high-pressure waterjet pumps — parts, seals, and service available worldwide through KMT's extensive dealer network
- Dual-intensifier design with enhanced hydraulic circuit reduces pressure pulsation, producing more consistent edge quality than single-cylinder pumps
- Available in HP ratings from 30 to 125 HP, covering everything from small prototype shops to high-throughput production facilities
- 90,000 PSI variant (SL-V 90 series) available for shops needing ultra-high pressure without migrating to Flow's HyperJet ecosystem
Limitations
- Intensifier design requires hydraulic oil system maintenance, including oil changes, hydraulic filter replacements, and leak monitoring — not required with OMAX's direct-drive EnduroMAX pump
- As a pump component rather than a complete machine, the Pro+ must be integrated with a cutting table — total system evaluation requires assessing the table OEM's engineering quality and support
- IDEKO remote monitoring requires subscription and connectivity infrastructure that smaller shops may not have in place

Frequently Asked Questions
01
KMT Waterjet Systems is a division of HPFG (High Pressure Fluids Group) and is the world's largest manufacturer of high-pressure waterjet pumps. KMT pumps power waterjet cutting machines from over 30 OEM partners globally, including WardJet, Techni Waterjet, PTV Waterjet, and many others. Flow International and OMAX build their own pumps, but much of the rest of the waterjet industry — from small regional OEMs to specialty machine builders — runs KMT pumps.
02
The Pro+ is an intensifier pump; the EnduroMAX is a direct-drive pump. Intensifier pumps use a hydraulic circuit to multiply pressure, requiring hydraulic oil maintenance. Direct-drive pumps connect the motor directly to the crankshaft, eliminating the hydraulic system. At 60,000 PSI, both deliver comparable cutting performance. The EnduroMAX has lower maintenance complexity and typically lower consumable costs in the first few years. The Pro+ has the broader global service network. Long-term total cost of ownership varies by usage pattern and location.
03
KMT's SL-V 90 series Streamline pumps operate at 90,000 PSI, compared to the standard Pro+ at 60,000 PSI. At 90,000 PSI, cutting speed on thick hard materials increases by approximately 30-40%. Component wear (seals, orifices, high-pressure tubing) accelerates significantly. The SL-V 90 is positioned for production shops where thick-plate cutting speed is a revenue bottleneck — similar to Flow's HyperJet 94i positioning but at 90,000 rather than 94,000 PSI.
04
At standard 60,000 PSI operation, Pro+ intensifier seals typically last 500-1,000 hours depending on water quality, pressure cycling frequency, and operating conditions. Seal kits run $1,000-$2,500 per cylinder. Most production shops budget annual seal replacement costs of $5,000-$15,000 for a dual-intensifier unit at moderate to heavy utilization. KMT's IDEKO monitoring system helps predict seal replacement before failures.
05
KMT pumps are technically compatible with most waterjet cutting tables that use standard high-pressure tubing and fittings — the 60,000 PSI connection is an industry standard. However, Flow and OMAX both warranty their machines with their own proprietary pumps, and mixing pump brands can create warranty and service complications. KMT pumps are most commonly paired with WardJet, Techni, PTV, and other OEM tables that are designed around KMT pump integration.
