description

The GM09 hydraulic pump adopts industrial super-heavy-duty variable axial plunger structure, with larger theoretical displacement, higher pressure resistance and stronger load impact resistance compared with 7-8 ton pump models. The core cylinder block and friction pair undergo ultra-precision mirror grinding and integral quenching hardening treatment, with excellent anti-wear, anti-pollution and high-temperature stability, effectively restraining internal leakage and pressure attenuation caused by long-time heavy-load operation and oil contamination. The upgraded thickened swash plate and high-precision load-sensing variable control mechanism ensure accurate flow and pressure follow-up output under heavy-load excavation, frequent commutation and long-duration continuous operation, solving the problems of weak excavation force, operation jitter and uncoordinated compound actions of old 9-10 ton excavators. The reinforced heavy-duty bearing assembly and vibration-damping structural design adapt to long-term high-intensity heavy-load construction, reducing pump body vibration, abnormal noise and early fatigue failure.

advantages

  • Mirror-Ground Hardened Friction Pair, Super Strong Heavy-Load Stability: The high-density forged cylinder block and super-hard alloy piston shoe are mirror-polished and integrally quenched, featuring ultra-high wear resistance and anti-pollution ability. It effectively suppresses internal leakage and high-temperature pressure drop under long-term super-heavy-load operation, maintaining stable high-pressure output and completely solving the problem of insufficient excavation power of old medium-large tonnage equipment.
  • High-Precision Load-Sensing Variable System, Ultra-Sensitive Response: The upgraded thickened reinforced swash plate variable mechanism realizes real-time load-following flow and pressure adjustment with minimal error and ultra-fast response. It eliminates operation jitter and uncoordinated compound actions, making the whole machine operate more smoothly and construction positioning more accurate and efficient.
  • Super-Heavy-Duty Reinforced Structure, Vibration & Noise Reduction: Optimized heavy-duty silent bearing and integral anti-fatigue structural design resists long-term super-heavy-load impact and frequent start-stop abrasion, reduces pump body vibration and running noise, and avoids early fatigue failure caused by high-intensity continuous operation of 9-10 ton excavators.
  • Strict Full-Factory Testing, Stable & Durable Performance: Each GM09 hydraulic pump undergoes full-pressure calibration, high-temperature long-cycle continuous operation test, variable precision detection and super-heavy-load fatigue aging test. The consistent and reliable performance ensures long-term stable and efficient operation of 9-10 ton excavators under various super-heavy-duty working conditions.

FAQ

  • Q1: What models is the GM09 hydraulic pump suitable for?
  • A: The GM09 hydraulic pump is universally applicable to all 9-10 ton domestic and imported mini excavators, compatible with most mainstream medium-large tonnage mini digging models on the market with excellent versatility.
  • Q2: What core faults can the GM09 hydraulic pump solve?
  • A: It repairs typical aging faults of 9-10 ton excavator hydraulic systems: insufficient heavy-load system pressure, weak excavation breakout force, slow compound action linkage, severe high-temperature pressure drop, excessive pump body noise, variable failure and persistent main pump oil leakage.
  • Q3: Is on-site modification or professional debugging required for installation?
  • A: No modification or debugging is needed. Standard universal mounting and interface size supports 1:1 plug-and-play direct replacement, fully matching the standard heavy overhaul process of 9-10 ton mini excavators.
  • Q4: The machine is still weak after replacing the GM09 hydraulic pump?
  • A: It is not a pump failure. Please check hydraulic oil cleanliness, filter blockage, main relief valve pressure parameters and pilot valve working condition. System oil pollution and parameter deviation are the main causes of weak power and slow linkage actions.
