Pump Casting refers to the process of manufacturing a pump housing or casing through the use of a casting process. A pump is a mechanical device used to move fluids, such as liquids or gases, by increasing the pressure or flow rate of the fluid. Pump casings are typically made using a casting process, which involves pouring molten metal or alloy into a mold and allowing it to cool and solidify. The resulting Pump Casting can then be machined, finished, and assembled with other pump components to create a complete pump unit.
