description

The GM18 hydraulic pump adopts industrial standard heavy-duty super-large-flow variable axial plunger structure, featuring larger displacement, higher pressure holding stability and stronger continuous heavy-load resistance compared with 15-17 ton pump models. The core cylinder block and friction pair undergo ultra-precision mirror grinding and integral high-temperature vacuum quenching hardening treatment, with excellent anti-wear, anti-pollution and thermal stability, effectively restraining internal leakage and power attenuation caused by long-term rock-breaking heavy-load operation and hydraulic oil contamination. The upgraded integral thickened reinforced swash plate and closed-loop high-precision load-sensing variable control mechanism ensure precise flow and pressure follow-up output under heavy-load excavation, frequent commutation and long-time continuous full-load operation, solving the problems of insufficient breakout force, operation jitter and uncoordinated compound actions of old 18-20 ton medium and large excavators.

advantages

  • Mirror-Ground Hardened Friction Pair, Super Strong Heavy-Load Stability: The high-density fully forged cylinder block and ultra-hard alloy piston shoe are mirror-polished and integrally vacuum quenched, featuring ultra-high wear resistance and anti-pollution ability. It effectively suppresses internal leakage and high-temperature pressure drop under long-term rock-breaking heavy-load operation, maintaining stable ultra-high-pressure and super-large-flow output and completely solving the problem of insufficient rock-breaking and excavation power of old medium and large-tonnage equipment.
  • Closed-Loop Load-Sensing Variable System, Ultra-Fast Response: The upgraded integral thickened reinforced swash plate variable mechanism realizes real-time closed-loop load-following flow and pressure adjustment with minimal error and ultra-sensitive response. It eliminates operation jitter and uncoordinated compound actions, making the whole machine operate smoother and construction positioning more accurate and efficient.
  • Standard Heavy-Duty Reinforced Structure, Vibration & Noise Reduction: Optimized heavy-duty reinforced bearing and integral anti-fatigue shock-absorbing structural design resists long-term heavy-load impact and frequent start-stop abrasion, reduces pump body resonance and running noise, and avoids early fatigue failure caused by high-intensity continuous operation of 18-20 ton medium and large excavators.
  • Upgraded Wide-Temperature Anti-Aging Sealing System, Zero Leakage: Equipped with new upgraded high-pressure and wide-temperature resistant anti-aging composite sealing components, which adapt to harsh construction environments and extreme temperature differences, permanently solve the recurrent oil leakage pain point of old main pumps, and reduce daily maintenance costs and failure rates.

FAQ

  • Q1: What models is the GM18 hydraulic pump suitable for?
  • A: The GM18 hydraulic pump is universally applicable to all 18-20 ton domestic and imported medium and large excavators, compatible with most mainstream standard engineering-tonnage excavation models on the market with excellent versatility.
  • Q2: What core faults can the GM18 hydraulic pump solve?
  • A: It repairs typical aging faults of 18-20 ton excavator hydraulic systems: insufficient heavy-load rock-breaking pressure, weak excavation breakout force, slow compound action linkage, obvious high-temperature pressure attenuation, severe pump body vibration and noise, variable response delay and recurrent 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 18-20 ton medium and large excavators.
  • Q4: The machine is still weak after replacing the GM18 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.
  • Q5: Daily maintenance tips for GM18 hydraulic pump?
  • A: Keep hydraulic oil clean, replace oil filter and return filter regularly; avoid long-term extreme full-load saturation operation; regularly check pump body for oil leakage, vibration and abnormal noise to effectively extend the service life of the standard heavy-duty main pump.
