Rethinking high pressure waterjet cutting
by Tim Wilson
Are we hitting the ceiling on PSI levels in waterjet technology? No, but a manufacturer can’t just roll out more power without making sure that it works effectively.
“Flow offers pumps that are rated up to 94,000 PSI,” says Tim Fabian from Flow International. “Beyond 94,000 PSI, there are constraints that require further technology development and research into specialized materials.”
Fabian says that Flow’s research and development department, which employs over 150 engineers and researchers, is actively working to solve the challenges faced with high PSI.
“Pumps well over 120,000 PSI have been tested in our facility,” says Fabian. “But Flow is not willing to release a product that will not provide consistent, proven performance.”
The good news is that even if it doesn’t result in a new generation of hyperpressure pumps, any research can inform product development. Jet Edge, for example, has just released new Permalign Edge technology that can produce parts with both zero taper and contour bevels up to 55 degrees – all while delivering to 90,000 PSI.
