New Tempest Dry Vacuum Pump

Each pump is meticulously and professionally hand assembled to ensure 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.
Our newest FAA-PMA edition has our patented Wear Indicator Port that allows for internal observation of the pump’s vanes. The WIP helps determine if the pump should be replaced, and helps avoid in-flight failure due to a pump exceeding its life cycle. Fins increase the cooling surface area by nearly 100% and also decrease weight. Our improved (inlet and outlet) stator porting reduces peak loads and improve airflow. The “by-polar” pumping action helps maintain balance rotor loading, reduces wear, and extends life. Chemically impregnated vanes and rotor increase natural lubricity, resist heat damage, and extend life. Even after hundreds of hours of operation, our pumps can be overhauled.
Warranty: Two years or 1250 hours and begins upon aircraft installation.
