How much does the Flow EchoJet cost?
Estimated price range
Our best estimate for a cnc waterjet cutting in this class — not a quote from Flow International. Configuration moves it a long way.
Overview
The Flow EchoJet is a compact waterjet cutting machine offered in one size: a 4'-3" × 4'-3" (1.3 m × 1.3 m) work envelope with 8 in (203 mm) of Z travel. Flow lists positioning accuracy and repeatability both at ± 0.001 in (± 0.025 mm), a rapid traverse of 500 in/min (12.7 m/min) and pressure up to 94,000 PSI (6,500 bar) with HyperJet.
Portability is the row that sets it apart. The frame has built-in forklift pockets, so the machine can be picked up and set down elsewhere when a shop layout changes or a cell is rebuilt.
On motion the EchoJet reads like the smallest Mach 200c. The Mach 200c lists the same ± 0.001 in (± 0.025 mm) accuracy, the same 500 in/min (12.7 m/min) rapid, the same ± 0.003 in (± 0.0762 mm) ballbar circularity and the same 8 in (203 mm) of Z. The Mach 150 is a step looser at ± 0.002 in (± 0.051 mm) and slower at 400 in/min (10.16 m/min), with 0.05 g of acceleration against the 0.1 g listed here.
Acceleration matters more than rapid rate on a table this size. Moves are short, so the head rarely reaches full traverse speed, and 0.1 g decides how quickly it gets through corners and small features.
Two points need checking before ordering. The 94,000 PSI figure applies with HyperJet, so confirm which pump is in the quotation and what pressure it runs at. And the envelope is fixed: stock longer than 1.3 m on either side does not fit, and Flow lists no larger EchoJet.

Strengths & Limitations
Strengths
- Built-in forklift pockets let the machine be moved when the shop layout changes
- Positioning accuracy and repeatability both ± 0.001 in (± 0.025 mm), with ballbar circularity of ± 0.003 in (± 0.0762 mm)
- 0.1 g acceleration, twice the 0.05 g of the Mach 150, which helps on short moves and tight features
- Pressure up to 94,000 PSI (6,500 bar) when paired with HyperJet
- 500 in/min (12.7 m/min) rapid traverse against 400 in/min (10.16 m/min) on the Mach 150
Limitations
- One size only: the 4'-3" × 4'-3" (1.3 m × 1.3 m) envelope cannot be ordered larger
- The 94,000 PSI (6,500 bar) figure is conditional on HyperJet; the table gives no pressure for other pumps
- Z travel is 8 in (203 mm); the NX Pro offers 12 in or 24 in (305 mm or 610 mm)
- No maximum cutting thickness or table load is listed

Frequently Asked Questions
01
4'-3" × 4'-3" (1.3 m × 1.3 m), with 8 in (203 mm) of Z travel. Flow lists a single size. If you need more table, the Mach 200c lists the same accuracy and rapid rate and comes in 1313, 3020 and 4020 sizes.
02
The frame has built-in forklift pockets, which is how Flow describes its portability. That covers lifting the machine itself. The table says nothing about what has to be disconnected first, so plan the water, power and pump connections with the installer.
03
Flow lists up to 94,000 PSI (6,500 bar) with HyperJet. The pressure you get depends on the pump supplied with the machine, and the table gives no figure for other pumps, so confirm the pump model in the quotation.
04
The EchoJet is tighter and quicker on paper. It lists ± 0.001 in (± 0.025 mm) positioning accuracy, 500 in/min (12.7 m/min) rapids, 0.1 g acceleration and ± 0.003 in (± 0.0762 mm) ballbar circularity. The Mach 150 lists ± 0.002 in (± 0.051 mm), 400 in/min (10.16 m/min), 0.05 g and ± 0.005 in (± 0.127 mm). Both have 8 in (203 mm) of Z travel, but the Mach 150 comes in three envelope sizes and the EchoJet in one.
05
Positioning accuracy is ± 0.001 in (± 0.025 mm) and repeatability is the same figure. Ballbar circularity, which shows how closely the two axes trace a true circle together, is ± 0.003 in (± 0.0762 mm).
