Application Example

(Vacuum Pump)

 * After pump disassembly and cleaning our scope was as follows…

 * Shaft and Rotor Assembly- Machine drive, seal and packing sleeve diameters and machine to prepare cone fits of rotor for coating.  Thermal spray with Hastelloy C and finish.

 * Cones- Thermal spray with Hastelloy C and finish grind to assure proper fit with rotor.

* Heads- Pressure test, machine inboard face and pilot diameter for coating and thermal spray with Hastelloy C and finish.
* Assembly- Assemble complete including bearings, seals, gaskets and packing along with dynamic balancing and painting as required.
The results?
Life of the pump
increased from 9-18 months to 5 years!
