Tempest 442CW Dry Air Vacuum Pump (Overhauled)
When Tempest receives a core, it is disassembled and all carbon is discarded. They never re-use carbon or the center stator. All parts are replaced with the possible exception of the end plates. The hard anodize is stripped from the center stator and the stator is inspected for cracks. They then perform a reconditioning of the I.D. After the reconditioning process, each stator is meticulously inspected for proper dimensions. The stator then receives a new hard anodize coating. They inspect 100% of the parts that are re-used in the overhaul process to make sure that each part meets the requirements for their FAA-approved process specification 203-6-1009.
