FAQ's

PurePulse waterjet technology is an ultrasonically pulsed waterjet stripping method designed to remove hard coatings/materials applied by thermal spraying (Plasma, Electric Arc, HVOF) and plating processes (Electro Hard Chrome, Nickel, etc.). This next-generation waterjet technology is designed as a safe, efficient, and environmentally friendly alternative for chemical stripping, gritblasting and machining. This method not only benefits part life extension, but also improves turnaround time and reduces throughput cost.

High-frequency electrical pulses are converted into mechanical vibrations that transform high-pressure streams of water into pulsed jets of individual water slugs. The water slugs produce a pulse-wave effect on the coating, gradually fracturing it and removing the coating from the substrate material.

PurePulse waterjet technology represents a substantial enhancement in waterjet technologies in terms of surface prepping performance. Operating at 30% of the pressure of traditional units, the technology works to compliment the ultra-high process through its ability to remove special coatings such as chrome and HVOF.

It works by creating a pulse wave effect, which in turn fractures the coating through water-eroding fracture.

The application of this technology results in a safer alternative to chemical dipping, gritblasting and grinding machining because no abrasives or chemicals are needed to strip hard or soft coatings. The technology operates using a closed-looped system, therefore hazardous coating materials can be captured, removed and managed as part of an environmentally-conscious waste stream management program.
