Gast K294A DOA/DAA Diaphragm Pump Service Kit – Repair & Rebuild for Oil-Less Models

The Gast K294A repair and maintenance kit is designed for oil-less diaphragm pumps with built-in filtration, such as the DOA-P701-AA model. This kit restores your pump to its original factory performance levels, ensuring reliability and efficiency. For optimal upkeep, servicing is recommended every two years. One kit is sufficient for DOA pump models, while DAA models require two kits. Included in the package are a leaf valve, limiters, an O-ring, a gasket, and filter/muffler elements to complete the rebuild process.

For additional maintenance, consider pairing this kit with AF818A (for pressure pump models) or AF818B (for vacuum pump models), depending on your unit’s configuration.
