The leak pipe K 70005 is an important monitoring and drainage component associated with the raw water pump K 73100 in the Sulzer ZV40/48 engine. Its primary purpose is to safely collect and direct any leakage from sealing areas or internal pump components to a designated location, allowing operators to identify seal wear or developing maintenance requirements at an early stage. Manufactured from corrosion-resistant materials suitable for continuous exposure to water, vibration, and varying temperatures, the leak pipe is designed for long service life in demanding marine and industrial environments. Its carefully engineered configuration ensures reliable drainage without interfering with normal pump operation. By supporting condition monitoring and helping prevent uncontrolled leakage, the K 70005 leak pipe contributes to improved maintenance planning, enhanced operational safety, and reliable cooling system performance.
