The Dana-Ridge Wetblast Process
The Dana-Ridge wet blast process is a unique wet blast finishing process. It utilises an abrasive media, water and compressed air to induce a scrubbing action on the surface of the material being processed. It is sometimes referred to as slurry blasting or (sometimes incorrectly) vapour blasting or vapour honing.
The Dana-Ridge wetblast process uses a gland-less pump to recirculate a wet slurry around the cabinet and onto the work surface. The added compressed air regulates the degree of water cushioning to the abrasive on the work-piece. The higher the pressure and volume of air, the more aggressive the Dana-Ridge wet blast process becomes. This control allows great flexibility.
The heart of the Dana-Ridge wet blast process is our unique gland-less, slurry pump. The pump design is specific for wet blasting, without bearings, seals, or packing. The interior parts of the pump, including the housings and impellor, are bonded with abrasion-resistant polyurethane. All these features combine to give the pump a long and relatively maintenance-free life.
The cut-away picture above shows how the Dana-Ridge wetblast process works. It thoroughly agitates the media and water and draws from a collection point at the bottom of the sump. This gives a consistent flow of slurry to the process gun ready for the compressed air atomisation. It allows a highly efficient blast compared to other methods of wetblasting.
The Benefits of the Dana-Ridge Wetblast System
Provides a superior finish
Uses a high volume, low pressure pump allowing multi-gun operation
Air used only to atomise to obtain desired degree of aggressiveness of blasting.
Pump simultaneously provides sump agitation
Allows for both gentle or aggressive blasting with control over the air supplied to the process gun.
Little to no damage to more delicate parts. No heat-damage.
Recirculation of media giving long life and reduced costs.
Multi-gun system fed from single pump so uniformity of flow and concentration are maintained.
Bonus is simultaneous degreasing and rust inhibition.
Long working life from the glandless urethane-lined pump
Maximum use of space in the hopper as the pump is mounted to the back of the machine. This also allows ease of access for maintenance.
Using its scrubbing action, contamination, surface deposits, scale or burrs are quickly removed and carried away, leaving a very clean and smooth surface.
They are commercial grade machines able to operate hour after hour in a busy workshop.
