description

The RMF148 pilot gear pump adopts ultra-high strength alloy steel gear pair and thickened integrated die-cast high-rigidity pump body, with overall structural reinforcement for anti-impact and anti-fatigue performance, fully adapting to the extreme variable-load cycle characteristics of large mining excavators. Through exclusive super-high pressure constant-pressure calibration and large-flow stable output optimization, it maintains strong and persistent pilot pressure output under long-term rock breaking and heavy-load impact conditions, avoiding pilot power insufficiency and action lag caused by load surge. Equipped with upgraded multi-layer composite high-pressure and high-temperature resistant oil seal and full-pressure anti-leakage structure, it resists high-frequency impact wear and high-temperature oil film failure of mining working conditions, effectively suppressing internal leakage and pressure drop under long-term ultra-high pressure operation. Adopting industrial-grade heavy-load damping and flow stabilization technology, the flow pulsation is minimized, ensuring coherent and powerful compound actions such as rock breaking, lifting and slewing of large excavators.

advantages

  • Mining-Grade Ultra-Heavy Load Calibration, Leading The Industry Tonnage Echelon: RMF148 is positioned as the top-tier mining super-heavy load model of the full product series. It upgrades on the basis of SBS140 ultra-high pressure performance, solving the problem of insufficient pilot pressure and weak rock-breaking power of conventional high-pressure pumps under extreme mine working conditions, perfectly matching the hydraulic demand of 20–30 ton large excavators for hard rock operation.
  • Super Strong Impact Resistance, Adapt To Extreme Rock-Breaking Conditions: Adopting thickened high-rigidity pump body and alloy steel reinforced gear pair, the overall impact resistance and structural toughness are greatly improved. It can resist frequent strong impact load during rock breaking and stripping, avoiding gear wear, pressure drift and early failure of ordinary pilot pumps in mine scenarios.
  • Ultra-High Pressure Constant Stability, No Attenuation In Long-Term High-Temperature Operation: Exclusive super-high pressure adaptive constant pressure system locks stable 32–38bar extreme pressure output. It effectively suppresses pressure attenuation and power weakness caused by long-term high-load and high-temperature continuous operation, ensuring consistent and powerful operating feel for full-condition rock breaking and heavy excavation.
  • Large-Flow Low-Pulsation Design, Smoother And Stronger Compound Actions: Optimized large-flow stable flow channel structure reduces hydraulic pulsation and impact, making the compound actions of rock breaking, lifting and walking of large excavators more coherent and powerful, eliminating the problems of sluggish response and weak digging force in heavy-load variable-load switching.

FAQ

  • Q1: What is the full-series gradient positioning of RMF148?
  • A: VRD63(0.6–1.8t Ultra-Light Precision) → TM40VD(0.8–2t Ultra-Micro Mute) → TSM72(2–3.5t Micro Heavy-Duty) → SG025/SG02(1–4t Small Tonnage) → SG04/SG08(4–8t Medium Heavy-Duty) → SG20(8–12t Industrial Heavy-Duty) → SBS120(12–16t Medium High-Pressure) → SBS140(16–20t Ultra-High Pressure) → RMF148(20–30t Mine-Grade Super-Heavy Duty). RMF148 is the top-tier flagship model of the full series for large mining excavators.
  • Q2: Which excavators is RMF148 suitable for?
  • A: RMF148 is exclusively applicable to 20–30 ton large excavators, especially optimized for mine rock-breaking, hard soil excavation and heavy-load frequent operation models. It is the dedicated ultra-heavy duty upgrade pump for large-tonnage harsh working condition equipment.
  • Q3: What core advantages does RMF148 have over SBS140?
  • A: SBS140 is positioned for 16–20t ultra-high pressure earthwork working conditions with limited anti-impact performance for rock breaking. RMF148 adopts mine-grade super-heavy load calibration, with higher pressure threshold, stronger impact resistance and better high-temperature stability, perfectly adapting to 20–30t large machine extreme mining working conditions that SBS series cannot support.
  • Q4: Is installation universal and lossless?
  • A: Yes. RMF148 completely replicates the OEM standard installation size, spline and interface of large excavators, supporting direct plug-and-play replacement without pipeline cutting or modification, zero installation error.
  • Q5: What is the maintenance standard for RMF148 mine-grade pump?
  • A: Use high-grade anti-wear hydraulic oil for mining machinery, replace filter elements regularly to keep oil clean. Avoid long-term overload operation beyond equipment limit. Maintain pilot pressure at 32–38bar to ensure long-term stable ultra-heavy load performance.
