Waterjet Cutting
Used Flow Mach 500: Sell or Buy at Auction
Flow International is the world's leading manufacturer of waterjet cutting systems: the technology pioneer that invented ultra-high-pressure waterjet cutting. Flow waterjet systems cut virtually any material including metals, composites, glass, stone, and rubber without heat-affected zones. Flow's Mach 500 and Dynamic Waterjet systems are the standard in aerospace, fabrication, and job shop environments.
The Flow Mach 500 is Flow Waterjet's high-performance ultra-high-pressure abrasive waterjet, built on a rigid bridge-style gantry and offered in a range of cutting envelopes from roughly 2 by 2 meters up to 4 by 8 meters, about 6.5 feet square at the small end to 13 by 26 feet at the large end. Its defining feature is Flow's HyperPressure system: the machine can run a 60,000 psi intensifier, but it is most often configured with the HyperJet pump that Flow rates at 94,000 psi and operates continuously near 87,000 psi, which cuts faster and uses less garnet than a standard 60,000 psi waterjet. Buyers pair it with either a standard three-axis head or Flow's Dynamic Waterjet XD, a five-axis cutting head that compensates for stream taper and cuts compound angles and beveled edges. Fabrication shops, aerospace and composite manufacturers, and stone and tile processors run the Mach 500 because one cold-cutting platform handles metals, composites, glass, and stone with no heat-affected zone, and the larger 4 by 8 meter tables take the oversized plate and panel work that would otherwise need a second machine. At auction, KD Auctions sees clean Mach 500 units draw active bidding from metal fabricators and job shops, especially those with a documented 94,000 psi HyperJet pump, low pump hours, and an intact Dynamic XD head. Sellers see the strongest results when the pump, catcher tank, and abrasive delivery system are documented as functional at time of sale, and that condition detail is what KD Auctions puts in front of its 500,000+ industry contacts.
Buying a Used Mach 500
Metal fabrication shops, aerospace composite manufacturers, stone and tile fabricators, glass processors, job shops, and any manufacturer cutting materials where heat-affected zones are unacceptable. Waterjet cutting has broad cross-industry appeal.

Frequently Asked Questions
What is a used Flow Mach 500 waterjet worth at auction?
Value depends on age, pump hours, overall condition, the control, table size, which pump the machine carries (a 60,000 psi intensifier versus Flow's 94,000 psi HyperJet), and whether it has the five-axis Dynamic Waterjet XD head or a standard three-axis setup. Rather than guess, KD Auctions offers a free AMEA-accredited, USPAP-compliant appraisal covering both orderly liquidation value (OLV) and forced liquidation value (FLV), so sellers know where their specific machine stands before deciding between auction and a direct cash purchase.
How does the Mach 500 compare with Flow's other waterjet models?
Within Flow's lineup, the Mach 500 sits above the value-oriented Mach 200 and mid-range Mach 300 in build, speed, and pump options, and below the large-format Mach 700. What most affects a used Mach 500's price is not a separate model but the configuration: the 94,000 psi HyperPressure HyperJet pump cuts faster and thicker than a 60,000 psi intensifier, and Flow's Dynamic Waterjet XD adds five-axis, taper-controlled cutting that a standard three-axis head cannot do. When comparing used units, weigh table size, which pump is installed, pump hours, and whether the XD head is present, since those drive both capability and what the machine brings at auction.
