What to Look for When Buying a Used Flow Waterjet
Flow waterjets are rugged, long-lived industrial machines, but a used Flow needs careful inspection of the pump, cutting head, motion system, and catcher tank before purchase.
Start with the high-pressure pump. The pump is the heart of every waterjet and the most expensive component to rebuild. On intensifier pumps (HyPlex, HyperJet, and legacy 87K/94K units), check total operating hours, hydraulic fluid condition, and any history of seal or check-valve rebuilds. Intensifier pumps typically need major seal service every 800 to 1,000 cutting hours. On direct-drive MotoJet and triplex pumps, verify pump hours, crankcase oil condition, and belt or coupling wear. Ask for rebuild records and confirm the pump holds rated pressure under load.
Inspect the cutting head and Z-axis. Orifices, mixing tubes, and on-off valves are routine consumables. Verify smooth Z-axis travel. On Pivot+ and 5-axis machines, confirm the articulating wrist moves freely and holds calibration for taper control. Older Dynamic Waterjet and Dynamic XD heads should be tested through the full articulation range.
Check the motion system and catcher tank. Corrosion is the biggest killer of used waterjets. Inspect ballscrews, linear rails, rack and pinion drives, and exposed steel for rust or abrasive damage. Look inside the catcher tank for excessive abrasive buildup and check the tank liner or dump system. Verify water supply and wastewater handling.
Identify the control and software version. Flow waterjets run on FlowMaster (2D) or FlowXpert (2D and 3D). Confirm the software license is transferable. Newer software runs on current Windows PCs; very old machines may have legacy controllers that require replacement if the original PC fails.
Flow Waterjet Models
Mach 100 and Mach 150
The Mach 100 is Flow's entry-level 2D waterjet, built with the same core components as premium systems in a simplified, programmable Z-axis package. The Mach 150 builds on this platform for small and mid-size job shops. Both are popular on the used market for shops entering waterjet cutting or adding secondary capacity.
Mach 200, Mach 200c and Mach 200s
The Mach 200 series delivers value-tier production cutting with genuine Flow components and optional Pivot+ 5-axis capability. The Mach 200c features Flow's canted-bridge design for full work envelope access, ideal for 3D cutting. The Mach 200s offers a standard open-gantry configuration. Available in table sizes from 1.3 m through 7.3 m.
Mach 300 and Mach 500
The Mach 300 is a compact production waterjet that minimizes floor space while delivering advanced Flow technology. The Mach 500 is Flow's flagship: the fastest and most accurate waterjet in the lineup, equipped with Dynamic Waterjet XD, Compass taper control, and the most advanced Flow motion and software suite. Both are high-demand on the used market.
Mach 700 Large-Format Waterjets
The Mach 700 series is Flow's heavy-industry large-format waterjet, available in single-bridge and dual-bridge configurations. Built for thick plate, oversized panels, and high-volume production. Common in aerospace, shipbuilding, heavy fabrication, and metal service centers.
NX Pro, NanoJet and EchoJet
The NX Pro is Flow's premium enclosed waterjet with fully automated abrasive recycling, energy-efficient pump technology, and intuitive new software. The NanoJet is a compact enclosed waterjet built for clean shop floors, medical, R&D, and precision work. The EchoJet delivers small-format cutting for entry applications.
How to Sell Your Used Flow Waterjet
Flow waterjets hold strong resale value thanks to the brand's global installed base, broad parts availability, and continued OEM support for legacy models. The Mach 200, Mach 300, Mach 500, and NX Pro are particularly high-demand on the used market.

Frequently Asked Questions About Used Flow Waterjets
Are used Flow waterjets reliable?
Yes. Flow invented abrasive waterjet technology and has built industrial waterjet systems for over 50 years. Machines are designed for 24/7 production, and with proper pump maintenance and consumables replacement, a well-maintained Flow delivers decades of service.
What software does a Flow waterjet use?
FlowMaster (FlowCut, FlowPath, FlowNest) handles 2D cutting, while FlowXpert and FlowXpert Infinity add full 3D and bevel cutting capability. Both run on standard Windows PCs and integrate with the machine control.
What is the difference between intensifier and direct-drive pumps?
Intensifier pumps (HyPlex Prime, HyperJet, legacy 87K/94K) use hydraulic pressure to amplify water pressure and are known for reliable 24/7 duty cycles. Direct-drive triplex pumps (MotoJet, MotoJet X) use a crankshaft-driven plunger design for higher efficiency and simpler maintenance. Flow is the only manufacturer offering both.
What materials can a Flow waterjet cut?
With abrasive, virtually anything: steel, stainless, aluminum, titanium, Inconel, stone, granite, glass, composites, carbon fiber, rubber, foam, and plastics. Pure waterjet cuts soft materials including food, gasket, and paper. Waterjet is a cold-cutting process with no heat-affected zone.
What Flow models hold their value best?
Mach 200, Mach 300, Mach 500, and NX Pro hold the strongest resale values, followed by Mach 700 large-format machines in specific markets. Dynamic Waterjet and Dynamic XD equipped machines command a premium. Call (844) 478-8181 for current valuations.
Can I still get parts for older Flow waterjets?
Yes. Flow continues to support legacy machines with OEM parts including orifices, mixing tubes, seal kits, check valves, and cutting head components, available directly from Flow and its service network.
