III. Hydac Gear Pump Naming Rule Explanation
-
PGE/PGI: Pump type code (PGE = External Gear Pump; PGI = Internal Silent Gear Pump)
-
100/102/103/104: Frame size code, representing pump body specification and pressure level
-
Digital Suffix: Displacement code (the last three digits represent 0.1cc/r unit; 320 = 32.0cc/r)
-
10A Series Code: High-pressure micro pump exclusive code, followed by shaft, seal and structure parameter suffixes.
