The pump rotor N 73111 is a precision-engineered rotating component designed for right-hand rotation in the Sulzer ASL25 engine’s pump system. Responsible for generating stable flow and pressure, this rotor ensures efficient fluid transfer under continuous operation. Manufactured with tight dimensional tolerances and balanced geometry, it minimizes vibration, reduces internal losses, and supports smooth pump performance. Its robust construction and wear-resistant surfaces contribute to long service life, reliable operation, and consistent system efficiency in demanding marine and industrial environments.
