Tempest offers a complete line of new and overhauled dry air pumps. Our pumps are FAA-PMA approved and meet the demands of today’s light aircraft.
All new and overhauled Tempest dry air pumps come with our 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. Our 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.
Tempest new dry air pumps offer a closed coupling area and our patented “LRT” diverter. These design features will help you detect and prevent pump contamination from external sources.
Rugged and lightweight, our 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. Our larger pumps also use hardened stainless-steel pressure plates that are precision ground and lapped to reduce internal leakage and wear.
About Tempest New Pumps
Each pump is meticulously and professionally hand assembled to insure proper tolerances and clearances. This assures optimum performance. After assembly, each pump is functionally tested. After this initial testing, the pump is then disassembled, inspected for any unusual wear or abnormalities, and reassembled for a second test run. This extensive testing procedure assures that only first-class products leave our facility.
About Tempest Overhauled Pumps
When Tempest receives a core, it is disassembled and all carbon is discarded. Tempest never re-uses carbon. We use a new stator on all 200 series pumps. Our larger 400 series pumps have the hard anodize stripped from the center stator and the stator is inspected for cracks. We then perform 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. We inspect 100% of the parts that we re-use in the overhaul process to make sure that each part meets the requirements for our FAA-Approved process specification 203-6-1009.
