Made of 17-4PH (630) steel, the blades achieve a hardness of HRC 40–45 after solution and aging heat treatment. High-precision cutting curves are achieved through a single five-axis CNC machining process, ensuring a stable clearance between the rotating and stationary blades. This allows for efficient pulverization of debris in domestic sewage and blackwater, preventing system clogging. This blade assembly is a core component of the 15MBD marine vacuum sewage pump, featuring corrosion resistance, high strength, and long life. Its structure is similar to the 25MBA series, but not universal.
