Alfa Laval P Separators
Built for precision, the P series separators are designed to handle varying flow rates and a wide range of oils with the proven performance of Alfa Laval’s disc-stack technology. These machines use a conventional gravity disc system to adjust separation, making them suitable for many standard and legacy fuel oil systems.
These separators are commonly used in both marine and land-based energy systems for cleaning heavy fuel oil (HFO), marine diesel oil (MDO), and lube oils. They are valued for their compact footprint, operational reliability, and ease of maintenance.
