Fast Coating Removal with Water
Ultra high pressure [UHP] water jetting for Surface Preparation

Blastmaster® makes water work!

For the toughest Industrial and commercial cleaning problem a high pressure water jetting system from Blastmaster® is the answer. You can harness the power of the water to provide an effi cient, cost effective, cleaning tool. Whatever the build-up - rust and scale, resins, chemical residues, paint, epoxies, a Blastmaster® Waterblaster system cuts right through it, spray rinses it away, and leaves a clean smooth surface.

Its faster than normal cleaning. No chemicals, solvents, caustics or abrasives are needed. [Or the expensive safety and disposal procedures that go with them]

Heavy Duty Pumps Deliver up to 40,000psi [2800 Bar]

The heart of any waterblast system is the high-pressure pump. With a range of models to choose from - both triplex and quintriplex designs - we can deliver pressures from 2000 to 40,000psi [140 - 2800 Bar]. Blastmaster® pumps can be electrically or diesel powered, and mounted on skids or trailers to go where you need them.

Top quality accessories like lances, patented Spinjet-nozzles, high pressure hose and system valves are available for virtually any application. Accessories are built to demanding specifi cations and vigorously tested before being released to the customer.

Why use UHP for Surface Preparation?

Ultra High Pressure [UHP] water is now being used for surface preparation in many applications. Unlike the atmosphere created by traditional abrasive blasting, UHP water jetting is dustless, minimizes waste by not using any abrasive and allows other activities to continue nearby while coating removal is in progress.

Instead of trapping contaminants in the surface profile, UHP water jetting actually removes soluble salts and contaminants from the bottom of the valleys. Surfaces prepared with UHP exhibit less folding and flattening, and feature a texture of sharp peaks generated by previous abrasive blasting which is conducive to bonding.

What can you do with 40,000psi?

Ultra High Pressure [UHP] Water Jetting can be used for many surface preparation projects. UHP will effectively and quickly remove tightly adherent coatings, paints and deposits from all surfaces without using any abrasive. In many cases, cleaning speed is comparable to that of abrasive blasting.

Applications especially suited to UHP 40,000psi are coating removal applications such as shipyard coating removal, offshore oil rigs, weld inspection, and plant maintenance like floor coating removal and machinery paint stripping. UHP does not produce a profi le rather it cleans out an existing underlying previously blasted profile. Opportunities exist wherever abrasive blasting equipment is currently in use.

UHP water jetting can produce a ‘white metal’ finish economically without the environmental and health hazards normally associated with traditional blasting methods.
