Feb 08, 2017 · Vacuum pump failure Unlike gyros, the vacuum pumps that drive them (by 'sucking' filtered air past turbine buckets machined into the gyro itself) tend to fail suddenly and without warning. In AWB 37-003 CASA says, 'Dry vacuum pumps can fail catastrophically and may also provide little or no indication to warn the pilot of imminent failure.

Why Vacuum Pumps Fail - AVweb

Why Vacuum Pumps Fail - AVweb

Almost every case of premature dry vacuum pump failure can be traced to one of three causes: contamination, overstress, or faulty installation. Dry air pumps are extremely vulnerable to contamination, particularly by liquids. The graphite vanes are designed to operate absolutely dry, and the introduction of any liquid can quickly destroy a pump.

Types of Aircraft Fuel Pumps | Aircraft Systems

Other than aircraft with gravity-feed fuel systems, all aircraft have at least one fuel pump to deliver clean fuel under pressure to the fuel metering device for each engine. Engine-driven pumps are the primary delivery device. Auxiliary pumps are used on many aircraft as well. Hand-operated fuel pumps use to back up the engine-driven pump and to transfer fuel from tank to tank.
