During the final‑assembly stage of a car, the paint‑curing oven and the robotic welding cells require a steady, contaminant‑free flow of coolant or hydraulic fluid to keep temperatures stable and actuators responsive. The electric drive pump EMP II is installed directly on the plant’s closed‑loop cooling circuit, feeding the heat‑exchanger that protects the body‑in‑white from thermal distortion. By delivering a consistent pressure, the pump enables the high‑speed conveyors to maintain the tight timing between stamping, welding and inspection stations, while also supplying the hydraulic cylinders that position heavy chassis components. In a paint‑shop, the same pump feeds the mist‑suppression system, ensuring that solvent vapors are removed without interrupting the line. Because the pump integrates with the plant’s PLC, operators can adjust flow rates on the fly to match the varying load of different vehicle models, reducing downtime caused by overheating or hydraulic lag. The result is a smoother transition from body assembly to power‑train installation, with the pump acting as the silent workhorse that keeps the fluid network humming.
