The Pesco 3P207JA Vacuum Pump is an engine-driven wet vacuum pump used in aircraft vacuum systems to supply suction for flight instruments such as attitude indicators and directional gyros. It is commonly installed on light aircraft platforms and is known as a direct replacement for Piper/Cessna part number 0870069-53, depending on configuration and installation requirements.

This pump uses an internal vane design to generate stable vacuum pressure from the engine accessory section. It is built for continuous operation in aviation environments and is typically oil-lubricated (“wet” type), which helps reduce internal wear and extend service life under normal operating conditions. The unit is designed for reliable performance under vibration, temperature changes, and long-duration flight cycles.

Used across various aircraft types (including Cessna and some Piper applications), the 3P207JA is a common OEM-equivalent vacuum source and is often replaced or overhauled during scheduled maintenance or engine accessory servicing.
