Pusher Washer or Disk for SprayTech ED655 Plus and AirCoat Systems
Part number 0278340 is a Pusher Washer or Disk specifically engineered for the SprayTech ED655 Plus airless pump and SprayTech AirCoat air-assisted airless spray systems. The ED655 Plus is a professional airless pump delivering reliable performance for residential and commercial painting applications. The AirCoat systems combine the speed of airless spraying with the fine finish quality of conventional air spray. This pusher washer or disk is a critical component within the pump assembly that applies force to seals and packings, ensuring proper compression and maintaining a leak-free seal under high pressure.
Manufactured from durable materials with precision-machined surfaces, this component transmits force from a nut or other fastener to the sealing elements, evenly distributing the load to ensure consistent seal compression. Proper function of the pusher washer is essential for maintaining the integrity of the fluid section and preventing material bypass. It may also serve as a bearing surface for rotating or reciprocating components.
This pusher washer is subjected to continuous high pressure, vibration, and potential corrosion. Failure modes include deformation, cracking, and wear. A damaged or missing pusher washer can lead to inadequate seal compression, causing pressure loss, leaks, and erratic pump operation. Replacement with genuine 0278340 pusher washer or disk restores proper seal loading and ensures reliable pump performance.
