3. Model Coding Rules (Core Explanation)

Marzocchi models follow a standardized structure for easy identification. Below is the general format:
[Series] [Group] – [Mount/Shaft] – [Displacement Code] – [Configuration/Option]
Code Segment
Meaning
Examples
Series
GHP/ALP/1P/ELI3/GHPP/ALPP
GHP = High-pressure cast iron; ALP = Full aluminum
Group
1/2/3/4 / 1A/2A/3A
GHP2 = Medium size; ALP3 = Large flow
D(S)
Mount/Rotation Direction
D = Clockwise; S = Counterclockwise; (S) = Dual direction
Displacement Code
Numeric code for displacement (cc/rev)
6 = 6 cc/rev; 40 = 40 cc/rev
FG/FC/MU
Configuration
FG = Flange type; FC = Port type; MU = Mount mode
S1/S2
Shaft Type
S1 = Splined shaft; S2 = Tapered shaft
RO/EO
Rotation Option
RO = Clockwise; EO = Counterclockwise
Example: GHP2A-D-20-FC-MU
= GHP series, Group 2A, Clockwise rotation, 20 cc/rev displacement, FC port type, MU mount mode .

4. Key Application Notes

  1. Temperature Range: Standard operation: -10°C to +80°C; max continuous temperature: +80°C .
  2. Inlet Pressure: TR version supports max 6 bar absolute inlet pressure; standard models require proper inlet priming .
  3. Modular Assembly: Combine elements from GHP/ALP/GHPP/ALPP series (e.g., GHP3A-D-80 + GHPP2-D-30) for custom flow/pressure .
  4. Customization: Marzocchi offers tailored options (flange, shaft, port, rotation, seals) for special applications .
