When you’re in the business of industrial cleaning and surface preparation, water blasting means the same – only the “competition” is the unwanted surface coating, and the pressurized water stream is a thousand times more powerful. The water blasting machines we manufacture here in North Charleston, SC, can produce pressures up to 40,000 psi. THE WATER BLASTING/CLEANING PROCESS Our Water Blaster use a positive displacement pump, which means that with every revolution of the crankshaft, the pump will displace a given volume of water. This displaced water can flow freely out the end of an open hose, or it can be forced to flow through a very small hole or nozzle orifice. The resulting operating pressure is determined by the size of the orifice through which the water must flow. The sm...
