description

The SG20 pilot gear pump adopts full industrial-grade thickened integrated forging structure and ultra-precision modified gear pair, specially optimized for 8–12 ton small excavator long-term ultra-high load cyclic operation. It adopts a super-large flow low-loss flow channel design, with a further increased displacement margin compared with SG08, realizing instantaneous massive flow supply during extreme load switching and high-frequency compound actions. The whole pump body is made of high-strength ductile iron integral casting, with ultra-high overall rigidity and shock resistance, effectively resisting structural deformation and vibration fatigue caused by long-term rock breaking impact. The upgraded micron-level super-finished gear pair and anti-wear floating bushing adopt industrial heavy-load matching standards, with ultra-low high-temperature friction loss and permanent stable volumetric efficiency. Equipped with a new-generation intelligent constant pressure compensation stabilization system, it achieves real-time dynamic pressure supplementation under full-load, high-temperature, and high-frequency working conditions, with zero pressure drop and zero flow fluctuation in the whole working cycle.

advantages

  • SG Series Flagship Flow & Pressure, Exclusive for 8–12 Ton Industrial Heavy Load: The SG20 raises the pilot pressure to 32–38bar with the industry’s top super-large flow reserve, completely breaking the performance limit of SG02/SG04/SG08. It perfectly solves the problem of insufficient pilot power and floating control of 8–12 ton small excavators during large-scale rock breaking and ultra-heavy load construction, matching industrial-grade full-load operation demands.
  • Industrial Intelligent Constant Pressure Compensation, Zero Pressure Drop in Full Working Condition: Equipped with a new-generation dynamic pressure compensation system, it actively supplements pressure according to load changes. No pressure fluctuation, no jitter, no action lag during frequent extreme load switching, maintaining ultra-precise and consistent control performance in industrial severe working conditions.
  • Four-Lip Ultra-High Pressure Resistant Seal, Permanent Zero-Leakage: Upgraded imported four-lip composite oil seal, with stronger high-temperature aging resistance and ultra-high pressure bearing capacity. It completely solves the high-temperature internal leakage, pressure loss and oil seepage failures that are unavoidable for ordinary pilot pumps under long-term industrial heavy load, realizing full-cycle zero-leakage operation.
  • Super-Large Flow Low-Loss Channel, Smoother Extreme Load Compound Actions: Industrial optimized oversized low-resistance flow channel minimizes hydraulic pulsation and flow resistance. The excavator’s slewing, lifting and digging compound actions are extremely coherent and smooth under ultra-full load, greatly improving industrial construction efficiency and operation stability.
  • 1:1 OEM Universal Industrial Upgrade, Zero Modification Cost: Fully compatible with original installation dimensions and hydraulic parameters, supporting plug-and-play industrial-grade upgrade. It comprehensively improves the hydraulic control upper limit of 8–12 ton small excavators, reduces industrial operation failure rate and long-term maintenance costs.

FAQ

  • Q1: What is the full gradient difference of SG02/SG04/SG08/SG20?
  • A: SG02 (1.5–4t, 25–30bar) for light & medium daily operation; SG04 (4–6t, 28–32bar) for medium heavy-load excavation; SG08 (6–8t, 30–35bar) for large micro excavator heavy rock working conditions; SG20 (8–12t, 32–38bar) is the industrial flagship model with maximum flow and pressure, exclusively for small excavator ultra-heavy load and long-cycle industrial construction.
  • Q2: Which equipment and main pumps does SG20 adapt to?
  • A: SG20 is dedicated to 8–12 ton large mini excavators and small excavators, fully compatible with all high-power large-displacement PVK series main pumps. It is the only industrial-grade supporting upgrade pilot pump for small excavators engaged in long-term rock breaking and heavy industrial construction.
  • Q3: What extreme faults can SG20 solve?
  • A: It completely solves industrial-level stubborn problems that SG02/SG04/SG08 cannot handle: long-term high-temperature severe pressure drop, ultra-heavy load operation jitter, large-flow compound action lag, weak pilot power during full-load rock breaking, and neutral drifting of large excavators, achieving full industrial-stable control.
  • Q4: Why do 8–12 ton small excavators must upgrade to SG20?
  • A: The pressure and flow margin of SG02/SG04/SG08 is insufficient for 8–12 ton industrial ultra-heavy load and long-hour continuous operation, which is prone to rapid performance attenuation and control failure. SG20 adopts full industrial-grade design with industry-top pressure and flow reserve, resisting extreme high temperature and heavy load, maintaining permanent stable performance without attenuation.
