description

The SG08 pilot gear pump adopts a full thickened ultra-high precision gear pair and integral heavy-duty reinforced cast pump body, specially optimized for extreme heavy-load cyclic operation of 6–8 ton large micro excavator pilot systems. Compared with SG04, it further increases effective displacement and flow reserve, optimizes ultra-low-loss large-flow channel structure, and achieves instantaneous high-flow rapid supply under extreme load switching conditions. The overall forged high-strength wear-resistant alloy gear set and thickened anti-wear floating bushing adopt micron-level ultra-finishing technology, with ultra-small matching clearance, minimal high-load friction loss, and far stronger anti-fatigue and anti-wear performance than conventional pilot pumps. Equipped with an upgraded ultra-high precision constant pressure stabilization system, it suppresses pressure and flow fluctuation in real time under full-load and high-temperature extreme working conditions, completely eliminating typical faults such as heavy-load jitter, compound action lag, and pilot pressure sudden drop of large excavators.

advantages

  • SG Series Top-Level Flow & Pressure, Exclusive for 6–8 Ton Ultra-Heavy Load: The SG08 upgrades the pilot pressure to 30–35bar with the largest flow reserve in the series, completely solving the insufficient pilot margin and floating control defects of SG02/SG04 when facing ultra-heavy load rock and hard soil working conditions. It perfectly matches the power demand of 6–8 ton large excavators’ full-load compound operations.
  • Full Reinforced Forged Structure, Extreme Anti-Fatigue Durability: Adopting fully thickened forged gear pair and super-rigid integral pump body, the overall structural strength is greatly improved. It can resist long-term high-frequency ultra-heavy load impact and vibration, with far lower wear and fatigue loss than ordinary pilot pumps, achieving ultra-long service life.
  • High-Temperature & High-Pressure Resistant Sealing, Zero Leakage in Whole Working Cycle: Upgraded imported triple-lip composite oil seal has stronger high-temperature aging resistance and high-pressure bearing capacity. It completely avoids high-temperature internal leakage, pressure loss and oil seepage faults that are prone to occur in ordinary pilot pumps after long-hour heavy-load operation.
  • Ultra-Low-Loss Flow Channel, Smoother Heavy-Load Compound Actions: Optimized large-diameter low-resistance flow channel minimizes hydraulic pulsation and flow resistance. The excavator’s slewing, lifting and digging actions are coherent and smooth under ultra-full load, greatly improving extreme-condition construction efficiency and operation fluency.
  • 1:1 OEM Universal Upgrade, Zero Modification Cost: Completely consistent with original factory installation dimensions and hydraulic parameters, supporting direct plug-and-play upgrade. It effectively upgrades the hydraulic control limit of 6–8 ton large excavators, reduces failure rate and lowers long-term maintenance costs.

FAQ

  • Q1: What are the differences between SG08, SG04 and SG02?
  • A: SG02 is a universal standard model for 1.5–4 ton light & medium-load excavators (25–30bar). SG04 is an upgraded heavy-duty model for 4–6 ton medium excavators (28–32bar). SG08 is the top ultra-heavy-duty version with 30–35bar ultra-high pilot pressure and maximum flow reserve, exclusively designed for 6–8 ton large excavators to solve extreme heavy-load jitter and pressure drop problems that SG02/SG04 cannot handle.
  • Q2: Which excavators and main pumps does SG08 fit for?
  • A: SG08 is dedicated to 6–8 ton large heavy-duty mini excavators, perfectly matching high-power large-displacement PVK series main pumps. It is the exclusive top-spec upgrade pilot pump for large micro excavators with long-term rock and hard soil heavy-load operation.
  • Q3: What core problems can SG08 solve?
  • A: It completely solves stubborn faults of large-tonnage excavators under extreme working conditions: insufficient pilot pressure margin, obvious high-temperature pressure drop, heavy-load operation jitter, unsmooth compound actions, slow hydraulic response, and neutral drifting, realizing full-stable high-precision control.
  • Q4: Why must 6–8 ton heavy excavators upgrade to SG08?
  • A: SG02 and SG04 have insufficient flow and pressure reserve for 6–8 ton ultra-heavy load and high-temperature working conditions, prone to performance attenuation and control failure. SG08 has industry-leading ultra-high pressure and large-flow margin, with extreme high-temperature and heavy-load resistance, maintaining long-term stable performance without attenuation.
  • Q5: What is the standardized maintenance for SG08?
  • A: Adopt high-grade clean anti-wear hydraulic oil and replace filter elements regularly to protect precision forged gear pairs. Avoid long-term extreme full-load impact operation. Regularly inspect high-pressure sealing components to prevent high-temperature leakage and pressure loss, ensuring long-term ultra-stable pilot pressure output.
