How much does the Flow HyperJet 94i 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 HyperJet 94i is a waterjet pump rated for a maximum generated pressure of 94,000 psi (6,500 bar) and a maximum operating pressure of 87,000 psi (6,000 bar). It is built in three power ratings, 30, 50 and 100 hp, with flow rates of .44, .73 and 1.46 gal/min (1.67, 2.76 and 5.53 l/min).
The two pressure figures are not interchangeable. 94,000 psi is what the pump can generate; 87,000 psi is the ceiling Flow gives for operation. Size the job on the operating figure. Flow rate is the other half of the choice, because it sets how large an orifice, or how many cutting heads, one pump can feed, and the highest rating delivers more than three times the water of the lowest.
Flow claims approx. 30% less garnet per inch of cut, though the table does not state what that is compared with. Against the saving, plan for seal service every 300-500 hours at 94,000 PSI, and for custom 94,000 PSI rated fittings and tubing: plumbing rated for lower pressure cannot be reused. Compatible cutting tables are given as the Flow Mach 500 and Flow Mach 700.

Strengths & Limitations
Strengths
- Maximum generated pressure of 94,000 psi (6,500 bar), with a maximum operating pressure of 87,000 psi (6,000 bar)
- Three sizes: 30, 50 and 100 hp, delivering 1.67, 2.76 and 5.53 l/min
- Approx. 30% less garnet per inch of cut is the abrasive saving Flow lists
Limitations
- Seal service interval is 300-500 hours at 94,000 PSI, so seal changes are a regular planned stop
- Requires custom 94,000 PSI rated fittings and tubing
- Only the Flow Mach 500 and Flow Mach 700 are named as compatible cutting tables

Frequently Asked Questions
01
94,000 psi (6,500 bar) is the maximum generated pressure. 87,000 psi (6,000 bar) is the maximum operating pressure. Flow lists both, and it is the operating figure that describes what the pump is rated to run at.
02
The three ratings are 30, 50 and 100 hp, with flow rates of 1.67, 2.76 and 5.53 l/min (.44, .73 and 1.46 gal/min). Flow rate decides how much water reaches the cutting head or heads, so choose on the orifice size and the number of heads you plan to run, then confirm the pairing with Flow.
03
Flow lists a seal service interval of 300-500 hours at 94,000 PSI. That makes seal work a recurring planned stop, so schedule it against pump hours and keep the parts on hand instead of waiting for a leak.
04
The compatible cutting tables Flow lists are the Flow Mach 500 and Flow Mach 700. The pump also needs custom 94,000 PSI rated fittings and tubing between pump and head, so a retrofit involves the high-pressure plumbing as well as the pump.
