[0002] A pump is a mechanical device used to increase the pressure of liquid or gas to make it flow. It can also be said to be a device used to move liquid, gas or special fluid media, that is, a machine that does work on the fluid. The components of the pump are mostly metal castings. After the casting is completed, the outer dimensions of the casting need to be fully checked. Usually, the casting is placed on a measuring platform and the dimensions are manually checked one by one using a vernier caliper, height gauge and ruler.
