Capitol has invested in the training and equipment to properly service turbopumps of all makes and models. Turbopumps require precision bearings installed with critical variables of load, tolerances, and lubrication. Certain rotor assemblies must be precisely balanced to eliminate noise and vibration and to maximize bearing life. Capitol guarantees that our procedures and components meet or exceed OEM specifications.

Only ultra-precision ceramic bearings are used. To balance rotor assemblies, we utilize a two-plane dynamic balancer which offers many advantages over a simple vibration analyzer. Unbalance in turbopump rotors can only be eliminated by mass correction in at least two planes perpendicular to the shaft axis. Our two plane dynamic balancer pinpoints the angle and mass of unbalance. Adjustments are carefully made until the balancer's microprocessor determines the assembly's residual unbalance is within tolerances.
Capitol Vacuum achieves a Balance Quality Grade of G-1(ISO1940/1 & ANSI S2.19) which provides superior bearing life.

We rebuild turbomolecular pumps & power supplies of all makes and models including:
