The Sulzer ZV40/48 diesel engine incorporates precision-engineered components to ensure efficient and reliable operation, including the stop for the fuel transfer pump, designated by code number K 74136. This component is critical for regulating and halting the operation of the fuel transfer pump, which is essential for maintaining controlled fuel delivery to the engine under varying operational conditions. Designed to endure high-pressure environments, the stop mechanism ensures operational safety and prevents fuel over-delivery, protecting both the pump and the engine from potential damage. Regular inspection and maintenance of this component are vital for sustaining the performance, longevity, and safety of the entire fuel management system.
