TEMPEST AERO® GROUP 442CW Air Dry Pump, 5-7/16 in L, 4.06 in Dia, 1/2-14, 11 psi

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 light-weight, 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.
