The support ring with code K 74131 is a key structural element in the fuel transfer pump of the Sulzer ZV40/48 engine. Positioned between the pump housing and mounting bracket, it ensures precise alignment and absorbs radial and axial loads generated during operation. By keeping the pump assembly firmly centered, this ring minimizes vibration and wear on internal components. Crafted from high-strength, corrosion-resistant material, it guarantees long-term stability and contributes to the smooth, reliable delivery of fuel under demanding marine or industrial conditions.
