Ordering Information

Each model designation includes:
  • Series (PV/PVM/PVT/PVR/Premier/Goldcup)
  • Displacement (cm³/rev) or model code (e.g., P080, P6)
  • Shaft extension type
  • Rotation direction (R: clockwise; L: counterclockwise)
  • Oil port direction and special features (e.g., tail drive, flange type)
Example: PV15-34.2-L-00-C1 (PV series, 34.2 cm³/rev, counterclockwise rotation, oil inlet downward, design code 00, seal grade C1)

Notes

  • The maximum instantaneous working pressure of PV29 and PVT29 is 27.5 MPa, and the maximum instantaneous working pressure of other models in PV/PVM/PVT/PVR series is 31.0 MPa[3].
  • PV/PVM/PVT/PVR series pumps have good interchangeability, which can replace other piston pumps that meet SAE installation standards[3].
  • All series support fire-resistant hydraulic fluids, which can be selected according to actual working environment requirements.
