ACF Serie

IMO AB ACF is the heavy-duty variant of the ACE series for large engines, boiler fuel supply and large transfer stations. Used on VLCCs, ULCCs, large container ships and cruise ships. More robust and durable than ACE, often used as booster pump upstream of MAN B&W or Wärtsilä main engines. Standard since 1990, continuously developed with current modular design.
