When Tempest receives a core, it is disassembled and all carbon is discarded. Tempest never re-uses carbon. A new stator is used on all 200 series pumps. Larger 400 series pumps have the hard anodize stripped from the center stator and the stator is inspected for cracks. Tempest then performs a reconditioning of the I.D. After the reconditioning process, each 400 series stator is meticulously inspected for proper dimensions. The stator then receives a new hard anodize coating. Tempest inspects 100% of the parts that are re-used in the overhaul process to make sure that each part meets the requirements of the FAA-Approved process specification 203-6-1009.

All new and overhauled Tempest dry air pumps come with Tempest’s patented WIP™ (Wear Indicator Port) that allows for internal observation of the pump’s vanes.  The WIP™ helps determine if the pump should be replaced and avoid unscheduled maintenance due to a pump exceeding its life cycle.  Tempest pumps also include finned stators for increased cooling and an “ultra-hard” finish on the internal wear surfaces of the stator for low friction and extended life.

Rugged and lightweight, the 240 and 400 series dry air pumps are designed with todays high performance aircraft in mind.  These pumps use a heat-treated, stainless-steel conical pressure plate spring and torsional dampening springs to provide a harmonics-free pressure plate control and smooth temperature compensation.  Larger Tempest pumps also use hardened stainless-steel pressure plates that are precision ground and lapped to reduce internal leakage and wear.
