description

The SBS140 pilot gear pump adopts full ultra-thickened heavy-duty forged gear pair and high-rigidity integrated alloy cast steel pump body, specially customized for the extreme heavy-load and long-cycle operation characteristics of 16–20 ton medium-large excavators. It adopts an upgraded super-large flow ultra-low-loss full-flow channel structure, further increasing instantaneous flow supply and dynamic pressure compensation capacity compared with SBS120, realizing zero-delay power response during extreme load switching and high-intensity compound actions. The overall high-strength precision forged gear set and thickened anti-fatigue floating bushing adopt military-grade super-finishing technology, with ultra-low high-load friction coefficient and permanent stable volumetric efficiency, effectively resisting long-term high-frequency extreme impact load and vibration fatigue. Equipped with a new-generation ultra-precision intelligent constant pressure stabilization system, it achieves real-time dynamic pressure compensation and flow adjustment, maintaining ultra-stable constant pressure output without attenuation or fluctuation under extreme working conditions of high temperature, full load and frequent load conversion.

advantages

  • Full Series Peak Ultra-High Pressure, Exclusive for 16–20 Ton Large Excavators: The SBS140 upgrades the pilot pressure to 35–42bar, the highest grade in the full SG/SBS series, with peak super-large flow reserve. It completely breaks the performance ceiling of SBS120, perfectly matching the extreme power demand of 16–20 ton large excavators for rock breaking and full-load heavy-duty construction, solving the long-standing industry problem of insufficient pilot power for large-tonnage extreme working conditions.
  • Full Intelligent Dynamic Pressure Compensation, Extreme Working Condition Zero Drop: Equipped with the latest generation of full-intelligent adaptive pressure compensation system, it actively senses load changes and performs real-time flow and pressure adjustment. No pressure fluctuation, no jitter, no response lag during frequent extreme load switching, maintaining ultra-precise and consistent control performance in mountainous, high-temperature and ultra-heavy load scenarios.
  • Military-Grade Forged Reinforced Structure, Ultra-Long Service Life: Adopting integrated alloy cast steel pump body and full ultra-thickened forged gear pair, the overall structural rigidity, impact resistance and anti-fatigue performance reach the full series peak. It can resist 24-hour long-term high-frequency extreme heavy-load impact and vibration, with extremely low wear loss, achieving industrial military-grade ultra-long service life.
  • Five-Lip Ultra-High Pressure Sealing, Permanent Zero-Leakage Operation: Upgraded imported five-lip composite high-temperature and ultra-high pressure oil seal, with top-level aging resistance and pressure bearing capacity in the series. It completely eliminates high-temperature internal leakage, pressure drop and oil seepage faults that are unavoidable for ordinary pilot pumps under long-term large-tonnage ultra-heavy load, realizing full-cycle permanent zero-leakage stable operation.

FAQ

  • Q1: Full gradient positioning of SG/SBS series pumps?
  • 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-ton high-pressure heavy load), SBS140 (16–20t medium-large ton ultra-high pressure extreme heavy load). SBS140 is the top flagship model of the full series, dedicated to large excavator extreme industrial heavy-duty working conditions.
  • Q2: Which equipment and main pumps is SBS140 suitable for?
  • A: SBS140 is exclusively customized for 16–20 ton medium-large engineering excavators, perfectly matching all mainstream super-large displacement high-power main pumps of large excavators. It is the only top-spec upgrade pilot pump for long-term large-scale rock breaking, hard soil deep excavation and mountain heavy-duty construction.
  • Q3: What extreme faults can SBS140 solve?
  • A: It completely solves the unsolvable industrial stubborn problems of small and medium-ton pumps: severe high-temperature pressure drop after long-hour ultra-heavy load operation, obvious floating control during full-load rock breaking, unsmooth large-flow compound actions, slow extreme-load hydraulic response, and idle pressure drift of large excavators.
  • Q4: Why can’t 16–20 ton excavators use SBS120?
  • A: SBS120 is limited to 12–16 ton medium excavators, with insufficient pressure and flow margin for 16–20 ton extreme heavy-load working conditions. Long-term use will cause performance attenuation, insufficient pilot power and frequent jitter. SBS140 has higher ultra-high pressure grade and peak flow reserve, specially calibrated for 16–20 ton large excavator extreme working conditions.
