PUMP: AIR,DRY,NEW,

Tempest AA441CC17 is a dry air vacuum 400 series pump. Tempest offers a complete line of new and overhauled dry air pumps. Tempest pumps are FAA-PMA approved and meet the demands of today’s light aircraft. All new and overhauled Tempest dry air pumps come with 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. The 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 patented “LRT” diverter. These design features will help detect and prevent pump contamination from external sources. Rugged and lightweight, Tempest 240 and 400 series dry air pumps are designed with today’s 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. The larger pumps also use hardened stainless-steel pressure plates that are precision ground and lapped to reduce internal leakage and wear.
