description

The GM07 hydraulic pump adopts industrial-grade miniature variable axial plunger structure, featuring compact overall layout, high volumetric efficiency and sensitive variable response. The core friction pair adopts precision grinding and high-hardness wear-resistant treatment, which greatly improves anti-wear performance and pressure resistance, effectively avoiding pressure attenuation and power decline caused by long-term oil contamination and high-frequency variable operation. The optimized swash plate angle control mechanism ensures stable flow output under no-load, light-load and variable-load conditions, solving the problems of jitter, uncoordinated compound actions and slow digging response of old mini excavators. The upgraded reinforced bearing assembly and anti-impact structural design adapt to frequent start-stop and sudden load changes of small construction equipment, reducing abnormal noise and early wear failure of the pump body. Equipped with multi-layer composite high-pressure and high-temperature resistant sealing kits, it resists long-term hydraulic oil erosion and seasonal temperature aging, completely solving the external oil leakage problem of the main pump.

advantages

Universal Full Compatibility, Lossless Direct Replacement: Adopts industry-standard flange installation, oil port size and interface parameters, widely compatible with 5-6 ton mainstream mini excavators. No pipeline cutting, shell modification or parameter debugging is required during on-site replacement, which effectively shortens equipment maintenance downtime and improves repair efficiency.
High-Precision Wear-Resistant Friction Pair, Stable Power Output: The cylinder block and piston shoe friction pair is precisely ground and hardened, with strong anti-wear and anti-pollution ability. It effectively suppresses internal leakage and pressure drop caused by oil contamination, maintains stable high-pressure output, and solves the problems of weak digging power and slow compound actions of old equipment.
Optimized Load-Sensing Variable Mechanism, Sensitive Response: The upgraded swash plate variable control structure matches the mini excavator hydraulic system perfectly, realizing rapid flow adjustment with load changes. It eliminates operation jitter and uncoordinated actions, making the whole machine operate smoother and more responsive.
Reinforced Anti-Impact Structure, Low Noise & Durable: Optimized internal bearing and anti-fatigue structure design resists frequent start-stop and sudden load impact, reduces pump body abnormal noise and vibration, and avoids early failure caused by long-term variable load operation of small excavators.
High-Grade Sealing System, Long-Term Anti-Leakage: Multi-layer composite high-pressure and high-temperature resistant sealing components adapt to complex construction site environments and temperature changes, permanently solve the oil leakage pain point of old main pumps, and reduce daily maintenance costs.
Strict Full-Factory Testing, Reliable Performance: Each GM07 hydraulic pump passes full-pressure calibration, high-temperature continuous operation test, variable sensitivity detection and fatigue aging test. The stable and consistent performance ensures long-term reliable operation of mini excavators under various fine working conditions.

FAQ

Q1: What models is the GM07 hydraulic pump suitable for?
A: The GM07 hydraulic pump is universally applicable to all 5-6 ton domestic and imported mini excavators, compatible with most mainstream small digging models on the market, with super versatility.
Q2: What main faults can the GM07 hydraulic pump repair?
A: It solves typical aging faults of mini excavator main hydraulic systems: insufficient system pressure, weak digging power, slow compound action, high-temperature pressure drop, pump body abnormal noise, variable failure and main pump oil leakage.
Q3: Is on-site modification or debugging required for installation?
A: No modification or professional debugging is needed. Standard universal mounting and interface size supports 1:1 plug-and-play direct replacement, fully matching the standard overhaul process of mini excavators.
Q4: The power is still weak after replacing the hydraulic pump?
A: It is not a pump failure. Please check hydraulic oil cleanliness, filter blockage, relief valve pressure and pilot valve working condition. System oil pollution and parameter deviation are the main causes of weak power.
Q5: Daily maintenance tips for GM07 hydraulic pump?
A: Keep hydraulic oil clean, replace oil filter and return filter regularly; avoid long-term high-load saturation operation; regularly check pump body for oil leakage and abnormal noise to extend the service life of the main pump.
