General Notes: 1. The “D(S)” in the model represents the installation and rotation direction; “FG” “FC” “MU” indicate special configurations such as flange type and mounting mode. 2. Specific parameters (such as flow rate, pressure grade, flange type, port size) vary with the model. For detailed dimensional parameters, order codes and installation instructions, please refer to the official Marzocchi product catalog. 3. Marzocchi gear pumps can be customized according to customer requirements, including displacement, pressure grade and connection mode, to adapt to special application scenarios. 4. Multiple modular gear pumps can be composed of different series elements (e.g., GHPA3.D.80 + GHPP2.D.30, ALPA2A.D.40.S1.E + ALPP2.D.40) to meet complex hydraulic system needs.
