description

The GM08 hydraulic pump adopts industrial heavy-duty variable axial plunger structure, featuring larger effective displacement, higher volumetric efficiency and more sensitive load-following variable response compared with conventional 5-6 ton pump models. The core cylinder block and friction pair undergo ultra-precision grinding and high-frequency quenching hardening treatment, with greatly improved wear resistance and anti-pollution ability, effectively suppressing internal leakage and pressure attenuation caused by long-term heavy-load operation and oil contamination. The upgraded thickened swash plate and stable variable control mechanism ensure accurate flow and pressure output under heavy-load excavation, frequent compound action and variable-load switching conditions, solving the problems of weak breakout force, operation jitter and uncoordinated actions of old 7-8 ton excavators. The reinforced heavy-duty bearing assembly and impact-resistant structural design adapt to long-term high-intensity construction working conditions, reducing pump body vibration, abnormal noise and early fatigue failure.

advantages

  • Universal Wide Compatibility, Lossless Plug-and-Play: Adopts industry-standard flange installation size, oil port position and interface parameters, widely compatible with all mainstream 7-8 ton domestic and imported mini excavators. No pipeline cutting, shell modification or parameter debugging is required during on-site replacement, greatly reducing equipment maintenance downtime and improving repair efficiency.
  • Hardened Precision Friction Pair, Strong Heavy-Load Stability: The forged cylinder block and alloy piston shoe are ultra-precision ground and quenched for hardening, with outstanding wear resistance and anti-pollution ability. It effectively suppresses internal leakage and high-temperature pressure drop under long-term heavy-load operation, maintaining stable high-pressure output and solving the problem of insufficient excavation power of old equipment.
  • Optimized Load-Sensing Variable System, Sensitive & Accurate Response: The upgraded reinforced swash plate variable mechanism realizes real-time load-following flow adjustment, with smaller adjustment error and higher response sensitivity. It eliminates operation jitter and uncoordinated compound actions, making the whole machine operate more smoothly and construction positioning more accurate.
  • Heavy-Duty Reinforced Structure, Vibration & Noise Reduction: Optimized heavy-duty bearing and anti-fatigue structural design resists long-term high-intensity load impact and frequent start-stop abrasion, reduces pump body vibration and abnormal noise, and avoids early failure caused by heavy-load operation of medium-tonnage mini excavators.

FAQ

  • Q1: What models is the GM08 hydraulic pump suitable for?
  • A: The GM08 hydraulic pump is universally applicable to all 7-8 ton domestic and imported mini excavators, compatible with most mainstream medium-sized mini digging models on the market with strong versatility.
  • Q2: What core faults can the GM08 hydraulic pump solve?
  • A: It repairs typical aging faults of 7-8 ton excavator hydraulic systems: insufficient system pressure, weak excavation breakout force, slow compound action, severe high-temperature pressure drop, pump body abnormal noise, variable failure and 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 overhaul process of 7-8 ton mini excavators.
  • Q4: The machine is still weak after replacing the GM08 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 actions.
