Q. What is the operation of a hydraulic intensifier?

Answer

The water pressure is "intensified" by a factor of 20:1 or more using hydraulic power in an intensifier-type pump. The system begins with a hydraulic pump that is turned by an electric (or gas/diesel-driven) motor to generate hydraulic oil pressure of about 3000 psi. The piston has a 20-times-smaller-diameter plunger attached to it. The water is drawn in during the retract cycle and the pressure is "intensified" to 60000psi or higher thanks to the plunger's work in a separate sealed high-pressure chamber and its 20:1 compression ratio.
