Overview
The Flow Mach 700 is Flow International's flagship waterjet, operating at 94,000 PSI (6,480 bar) using the HyperJet pump -- the highest commercially available waterjet pressure. It cuts 40-50% faster than 60,000 PSI systems on thick materials while using less abrasive per inch.
Table sizes range from 1,500 x 3,000 mm to 4,000 x 8,000 mm. Positioning accuracy is +/- 0.025 mm (0.001 in) and repeatability +/- 0.013 mm (0.0005 in). The HyperJet dual-intensifier pump is rated to 150 HP with iP intelligent monitoring.
Supports up to 4 simultaneous cutting heads with Dynamic Waterjet XD for 5-axis bevel cutting to 60 degrees. FlowXpert with SmartStream controls cutting; FlowMaster HMI provides monitoring and remote diagnostics.
Heavy-duty stress-relieved steel frame with deep catcher tank for 94,000 PSI energy levels. Machine weight 5,000-15,000 kg. New systems $400,000-$800,000+; fully loaded multi-head systems exceed $1,000,000.

Strengths & Limitations
Strengths
- 94,000 PSI cuts 40-50% faster than 60,000 PSI on thick materials
- Industry-leading positioning +/- 0.025 mm and repeatability +/- 0.013 mm
- iP pump monitoring predicts wear before failures
- Up to 4 simultaneous heads multiply production throughput
- Dynamic XD at 94,000 PSI produces highest-quality waterjet cuts available
- FlowMaster HMI enables remote monitoring and fleet management
Limitations
- $400,000-$800,000+ requires high utilization to justify
- 94,000 PSI accelerates seal, orifice, and mixing tube wear
- HyperJet maintenance is specialized and expensive
- Deeper tank increases floor space requirements
- Garnet quality is critical -- inconsistent abrasive damages components

Frequently Asked Questions
01
$400,000-$800,000 single-head. Multi-head with Dynamic XD exceed $1,000,000. Used (2019-2023) $200,000-$450,000.
02
40-50% faster on thick materials, nearly 2x on 3-inch steel. Uses ~30% less abrasive per inch.
03
300-500 hours at 94,000 PSI vs 500-1,000 at 60,000. Seal kits $1,000-$2,500/cylinder. Budget $15,000-$25,000/year.
04
Yes, at 0.5-1.0 ipm. Often the only process for this thickness without heat distortion.
05
500 runs 87,000 PSI, 700 at 94,000 with tighter specs, faster rapids, larger tables. 500 offers ~80% performance at lower cost.
