Liquid Ring Vacuum Pump

I recently had to replace one of these at work as the motor was damaged during a power outage. I decided to disassemble it for an inspection. I kind of became fascinated with it and decided to model some of the parts. The model is based on a NASH Liquid Ring Vacuum Pump, Model 2AV1 060. Dimensions on the detailed components, i.e., shaft/armature, turbine, fan blade, fan cover are +-1mm. The motor, pump head, etc. are not nearly as detailed. Done with Inventor 2013, all part files are included. In addition a .stp file of the assembly is included for others.
