Dust-suppressed blasting for rust, paint and scale
Riggers Pumps supplies wet sandblasting equipment from Chennai, India. We specialize in designing, manufacturing, and exporting wet sandblasting machines, hydro sandblasters, and wet blast systems for industrial surface cleaning and preparation. Our water sandblasting machines are used across multiple sectors including engineering, fabrication, shipbuilding, power generation, and construction. These systems efficiently remove rust, paint, scale, grease, and oxidation, preparing surfaces for coating, painting, or welding with precision. We build reliable, cost-effective wet blasting machines with lower dust and environmental impact than dry blasting.
What is a wet sandblasting machine?
A wet sandblasting machine, also known as a hydro sandblaster, is a surface cleaning device that combines high-pressure water with abrasive materials such as garnet or aluminium oxide. This mixture is expelled through a specially designed nozzle to remove rust, paint, corrosion, scale, and contaminants from metal or concrete surfaces. Unlike dry sandblasting, the wet blasting process uses water to suppress dust and static friction, making it safer for both the operator and the environment. The result is a smooth, consistent, and contaminant-free finish suitable for repainting, coating, and precision polishing. Our wet sandblasting equipment balances efficiency, surface quality, and environmental protection, making it ideal for industries that require clean, durable, and corrosion-resistant surfaces.
How wet sandblasting works
In a wet sand blasting machine, the abrasive media is mixed with high-pressure water generated by a pump. The slurry is then directed at the target surface through a nozzle. The kinetic energy of the water combined with the abrasives dislodges contaminants, rust, or old coatings effectively.
The water serves several key functions:
It suppresses dust, reducing operator exposure to airborne particles.
It prevents overheating or warping of delicate components.
It provides a smooth surface finish without aggressive abrasion.
This process, often called water sandblasting or wet abrasive blasting, ensures better cleaning efficiency and is particularly suitable for surfaces where dry blasting could cause damage.
Advantages of wet sandblasting

Frequently asked questions
Straight answers to what buyers ask us most. Can’t find yours? Ask our team.
What is wet sandblasting and how does it work?
Wet sandblasting mixes abrasive media with high pressure water from a triplex plunger pump and directs the slurry at the surface through a nozzle. The abrasive removes rust, paint and contaminants, while the water suppresses dust and heat, giving a smoother finish than dry blasting.
What is the difference between wet and dry sandblasting?
Dry sandblasting propels abrasive with compressed air and creates heavy dust and surface heat. Wet sandblasting uses water to carry the abrasive, which keeps dust very low, prevents heat distortion, reduces static and gives a more even satin matte finish. Dry blasting can be faster on heavy profiles where dust can be contained.
Which abrasives can be used with a wet sandblasting machine?
Common media include garnet, aluminium oxide, glass beads, plastic beads and baking soda. Garnet and aluminium oxide suit rust and paint removal, while glass beads, plastic beads and soda suit lighter cleaning and delicate parts. Avoid silica sand because of the health risk from silica dust.
What pressure and flow do your wet blasting machines use?
The RP-14 model works at 140–250 bar with 14–18 LPM and suits portable or skid-mounted use. The RP-25 model works at 200–500 bar with 25–30 LPM for stationary or mobile set-ups. The higher model suits thicker coatings and larger areas.
Is wet sandblasting suitable for delicate surfaces?
Yes, in most cases. The water cushions the abrasive impact, so aluminium, stainless steel and precision components can be cleaned with less risk of damage. Use a fine media and lower pressure, and test on a sample part first. Ask us for a media and pressure recommendation for your parts.
Which industries use wet blasting equipment?
Wet blasting is used in shipbuilding, power generation, automotive, construction, pharmaceuticals, cement, engineering and metal fabrication. Typical jobs are paint and rust removal, weld cleaning, deburring, machinery maintenance and restoration of building facades. Wet blasting is preferred where dust control matters, such as in occupied buildings or near sensitive equipment.
Do you supply portable and stationary wet blasting machines?
Yes. Riggers Pumps supplies portable and skid-mounted wet sandblasting machines for on-site work and stationary or automatic systems for workshop and production use. Tell us where and how often you will blast so we can suggest the right set-up. Both are built around high pressure triplex plunger pumps.
What does a wet sandblasting machine cost?
The cost depends on pressure, flow, motor power and configuration, such as portable, skid-mounted or cabinet type. Share your application, surface, abrasive and preferred set-up and we will send a quotation for the matching model. We can also suggest the abrasive feed and nozzles to suit your job.
What maintenance does a wet sandblasting system need?
Check nozzles, pump seals, hoses and filters regularly, and flush abrasive out of lines after use. Nozzles wear with use and should be replaced when the pattern widens. Riggers Pumps supplies spares and service support from Chennai. Keep a set of spare nozzles and seals in stock to avoid stoppages.
