Fuel Pump Filter Differential Pressure Switch Repair & Overhaul
FAA & EASA certified fuel pump filter differential pressure switch repair and overhaul.
About the Fuel Pump Filter Differential Pressure Switch
A fuel pump filter differential pressure switch monitors the pressure drop across a fuel filter element and actuates when that differential rises to a set limit, indicating filter clogging or impending bypass. Mounted at the fuel pump filter within the sensors and switches domain, it provides crew indication or impending-bypass warning so contaminated or restricted filters are detected before unfiltered fuel passes downstream. The switch senses upstream and downstream pressure across a diaphragm or piston that closes contacts at the setpoint. Repair and overhaul are driven by diaphragm fatigue and rupture, contact erosion and pitting, calibration drift of the differential setpoint, spring fatigue, fuel-side contamination and corrosion, seal and O-ring degradation causing leakage, and electrical terminal deterioration that produces false indications or failure to actuate.
