Increase your productivity with a Rotating Lance.

When you blast with ultra-high pressure water jetting you can increase your performance by using a rotating lance gun that gives you a wider blasting pattern, because they have multi-orifice heads.

UHP rotating lances use an air-driven motor that drives the nozzle assemblage. To use these rotaing lances a Bi-Mode™ valve and a composite hose assembly is required.

Bi-Mode™ valves let multiple operators run lances from a single UHP pump.

Ultra-High Pressure Waterjet Nozzles

To actually get water coming out of a nozzle at 40,000 psi is really expensive, so when it gets there, its important to use the best nozzle to do the job.

Sapphire & Diamond Nozzle

BlastOne Ultra-Jet Blast nozzles have a special micro-chamber behind the actual nozzle that do more work then other nozzles.

  1. Reduce pulsation of the water to get your operator a consistent flow and working pattern
  2. Smooth out the working water so the operator can stand further from the surface and get higher productivity

The office is made up of sapphire and diamonds and tested to a very tight tolerance, then encased in stainless steel, to ensure you get the productivity you need  on every jobsite.

Nozzles are designed for use at 40,000 psi.
