Intensifier pumps are commonly used in waterjet cutting machines because they are capable of generating extremely high pressures, which are necessary for cutting through tough materials. Waterjet cutting machines can use different types of intensifier pumps, including direct drive pumps and crankshaft-driven pumps, but the hydraulic intensifier is the most common type used in waterjet cutting applications.

The hydraulic intensifier consists of a hydraulic cylinder and a reciprocating piston that is driven by a hydraulic pump. The piston moves back and forth, compressing the water and increasing its pressure. This high-pressure water is then delivered to the cutting head, where it is directed through a tiny nozzle to create a precise, high-velocity waterjet stream that can cut through a variety of materials.

One of the key advantages of waterjet cutting machines is their ability to cut through a wide range of materials without producing heat-affected zones (HAZs) or introducing thermal stress into the material. This is because the cutting process uses water instead of a heat source such as a laser or plasma torch. The high-pressure waterjet stream is able to cut through materials by eroding the surface of the material, rather than melting or vaporizing it.

The performance of the intensifier pump is critical to the overall performance of the waterjet cutting machine. A poorly maintained or malfunctioning pump can result in reduced cutting speeds, lower quality cuts, and increased downtime due to equipment failure. Regular maintenance and inspection of the intensifier pump can help ensure that the machine is operating at peak performance and minimize the risk of costly equipment failures.
