Origin Metrology Group has developed precision inspection routines utilizing multiple laser tracker systems to inspect, align and analyze the components of industrial pumps and compressors. The inspection process consists of measurements from the pump body, rotors and bearing brackets. The report combines all measurements and provides in-depth dimensional analysis through virtual assembly and cad integration.
