A pump skid is a pre-engineered and pre-fabricated assembly of pumping equipment and RO filters. A skid would typically include pumps, valves, piping, and electrical controls, filters, bypass systems and would be mounted on a steel base or skid. It is used to transfer liquids or gases in various industrial, commercial, and residential applications. Pump skids are designed to simplify the installation process, reduce costs, and provide a compact and self-contained system that can be easily relocated or transported to different locations.
