ABB 3AFV3527603 Spiral Seal Bushing for AZIPOD Podded Propulsion
I. Product Overview
The ABB 3AFV3527603 is a spiral seal bushing supplied by ABB for the Azipod podded propulsion shaft seal system, with material number 3AFV3527603. This bushing is installed in the Azipod propeller shaft seal system, providing auxiliary sealing through the pumping effect of spiral grooves machined on its bore surface as the shaft rotates, and returning leaked fluid, serving as a key sealing element of the shaft seal system.
The Azipod propeller shaft seal system adopts a multi-seal ring arrangement between the propeller bearing and the propeller, forming multiple chambers: the outermost chamber is filled with grease as a dirt barrier, and the second chamber is filled with pressurized air, insulating bearing oil from seawater. The spiral seal bushing, as a component of this seal system, works in conjunction with the seal rings, enhancing sealing performance through the pumping effect of the spiral grooves, preventing oil leakage to sea and blocking seawater ingress into the bearing sump.
The 3AFV3527603 spiral seal bushing carries an official ABB Marine & Ports material number (3AFV code system), suitable for vessel dry-docking, periodic seal inspection and replacement of corresponding Azipod podded propulsion. For specific dimensions, material, spiral groove parameters, matching shaft diameter and other technical parameters, please contact via email for confirmation.

VII. FAQ
Q1: What is 3AFV3527603 and which equipment is it used on?
A: 3AFV3527603 is a spiral seal bushing supplied by ABB for the Azipod podded propulsion shaft seal system, providing auxiliary sealing via the pumping effect of spiral grooves.
Q2: What is the sealing principle of the spiral seal bushing?
A: Spiral grooves are machined on the bore surface of the bushing; as the shaft rotates, the grooves create a pumping effect that returns leaked fluid, working with multiple seal rings to form multi-stage sealing, preventing oil leakage and seawater ingress.
Q3: What are the technical parameters of this bushing?
A: Dimensions, material, spiral groove parameters, matching shaft diameter, working pressure etc. are ABB dedicated material parameters, please contact via email for confirmation.
Q4: How to confirm this bushing's compatibility with the existing Azipod propulsor?
A: Please provide the existing Azipod model, seal tag number and nameplate information, contact via email, and we will assist in confirming compatibility and provide technical documentation.
