A pump on a waterjet machine generates the high-pressure water needed for cutting by taking low-pressure water into a cylinder, compressing the water with a plunger and then pushing the high-pressure water out of the cylinder. During a pressure cycle of intake, compression and expulsion, high-pressure components and polymer seals see the water pressure jump from two-digit inlet pressures to outlet pressures in the tens of thousands of psi.
