The moment the paint-mix tank on the robotic arm begins its cycle, the pump mounted beneath the carriage draws in the thinned primer. Its impeller, sealed with a fluoroelastomer mechanical seal, pushes the viscous fluid through the flexible hoses to the spray nozzles without allowing a single drop to escape—even when the arm accelerates to full speed or tilts the tank. In motor vehicle manufacturing, this pump sits inside the automated paint line, where it handles solvents, water-based primers, and clear coats at the exact flow rate the robots require. The aluminum housing keeps weight low so the arm can move quickly, while the three-phase motor matches the plant’s power grid without extra converters. On the adjacent assembly line, the same pump circulates coolant through the welding robots’ heat exchangers, ensuring the spot-welding guns stay within temperature limits during continuous operation.
