5. Notes

  • All parameters are measured under standard conditions: 1450 rpm, HM hydraulic oil (ISO VG 32), 50℃ oil temperature.
  • Pressure peaks exceeding 30% of the maximum operating pressure must be eliminated by appropriate measures.
  • The drain port must be connected independently to avoid back pressure affecting pump performance.
  • Regular maintenance of hydraulic oil cleanliness is recommended to extend the pump’s service life.
