description

The SBS120 pilot gear pump adopts full heavy-duty thickened reinforced gear pair and high-rigidity integral cast steel pump body structure, specially customized for the long-term high-intensity heavy-load cycle operation characteristics of 12–16 ton medium excavators. It optimizes large-diameter low-resistance full-flow channel, greatly improving instantaneous flow supply capacity and pressure compensation speed under continuous variable load conditions. The high-strength alloy forged gear set and thickened wear-resistant bushing adopt industrial super-finishing technology, with ultra-low friction coefficient and stable volumetric efficiency, effectively resisting wear and fatigue caused by long-term high-frequency impact load. Equipped with an upgraded high-precision dynamic constant pressure stabilization system, it realizes real-time dynamic pressure supplement during frequent load switching, maintaining ultra-stable pressure output under long-hour full-load and high-temperature working conditions without pressure attenuation or fluctuation.

advantages

  • Medium Excavator Exclusive High-Pressure Grade, Surpassing SG Series Limit: The SBS120 upgrades the pilot pressure to 33–40bar with super-large flow reserve, breaking the performance ceiling of the SG20 8–12 ton industrial model. It perfectly matches the high-power output demand of 12–16 ton medium excavators, completely solving the problems of insufficient pilot margin and weak control of SG series models in medium and large-tonnage heavy-load construction.
  • Dynamic Pressure Compensation, Full-Condition Zero Pressure Drop: Equipped with self-developed intelligent dynamic pressure compensation system, it actively adjusts flow and pressure according to load changes. No jitter, no lag, no pressure fluctuation during frequent switching of earthwork, stone loading and other compound working conditions, maintaining ultra-precise and consistent control performance.
  • Cast Steel Reinforced Structure, Super Strong Anti-Impact Durability: Adopting integral cast steel pump body and fully forged thickened gear pair, the structural rigidity and impact resistance are greatly improved. It can resist long-term high-intensity vibration and heavy-load impact of medium excavators, with extremely low wear loss and far longer service life than ordinary industrial pilot pumps.
  • Multi-Lip High-Pressure Sealing, High-Temperature Continuous Operation Stable: Upgraded imported multi-lip composite high-temperature and high-pressure oil seal, with strong aging resistance and pressure bearing capacity. It completely solves the stubborn faults of high-temperature internal leakage and pressure drop that are easy to occur in medium excavators after long-hour continuous heavy-load operation.

FAQ

  • Q1: What is the positioning difference between SBS120 and SG series full models?
  • A: SG025 (1–3t mute precision), SG02 (1.5–4t light & medium load), SG04 (4–6t medium heavy load), SG08 (6–8t rock heavy load), SG20 (8–12t industrial ultra-heavy load), SBS120 (12–16t medium excavator high-pressure heavy load). SBS120 is the exclusive high-pressure upgraded model for medium excavators, filling the performance gap above 12 tons with 33–40bar ultra-high stable pressure.
  • Q2: Which equipment is SBS120 suitable for?
  • A: SBS120 is exclusively developed for 12–16 ton medium-sized engineering excavators, perfectly matching all mainstream large-displacement high-power main pumps of medium excavators. It is the dedicated heavy-duty upgrade pilot pump for long-term large-area earthwork and high-intensity loading construction.
  • Q3: What core faults can SBS120 solve?
  • A: It completely solves the industry stubborn problems of 12–16 ton medium excavators: insufficient pilot pressure margin during full-load operation, obvious high-temperature pressure drop after long-hour continuous work, unsmooth compound loading actions, slow hydraulic response and floating control, realizing full-stable high-precision heavy-load control.
  • Q4: Why can’t 12–16 ton excavators use SG20?
  • A: SG20 is only suitable for 8–12 ton small excavators, with limited pressure and flow margin. When used on 12–16 ton medium excavators with higher power and heavier load, it will cause insufficient pilot power, severe performance attenuation and frequent jitter faults. SBS120 has higher pressure grade and larger flow reserve, exclusively adapted to medium excavator heavy-load working conditions.
