description

The RMF147 pilot gear pump adopts high-rigidity thickened die-cast aluminum alloy pump body and upgraded reinforced low-pulsation gear pair, with structural strength upgraded on the basis of SBS series earthwork pumps and parameter optimization downgraded reasonably based on RMF148 full mine-grade configuration, forming a professional transition heavy-load positioning. Through exclusive high-precision transition pressure calibration and flow channel damping optimization, it maintains stable and linear pressure output during frequent switching of heavy earthwork loading, hard soil excavation and medium-strength rock breaking. It effectively suppresses hydraulic pulsation and high-temperature pressure drift of 18–22 ton equipment, ensuring sensitive and coherent compound actions. Equipped with upgraded high-temperature and impact-resistant composite oil seal, it adapts to long-cycle variable-load operation of medium-large excavators, avoiding internal leakage and performance attenuation caused by frequent heavy-load impact.

advantages

  • Exclusive 18–22t Transition Positioning, Fill Full-Series Performance Gap: RMF147 accurately covers the blank of 18–22 ton mixed working condition equipment. It avoids the insufficient pressure margin of SBS140 purely earthwork pumps under frequent heavy loads, and eliminates the performance redundancy and cost waste of RMF148 full mine-grade pumps for moderate working conditions, achieving precise one-to-one matching for transition tonnage models.
  • High-Temperature Anti-Drift Stabilization, Stable For Long-Term Variable-Load Operation: Optimized transition-grade constant pressure system effectively suppresses high-temperature pressure attenuation and idle floating pressure of 18–22 ton equipment during long-term heavy-load operation. The operating feel is linear and consistent from low-speed fine trimming to full-load heavy excavation, with no jitter or weakness.
  • Reinforced Low-Pulsation Design, Smoother Compound Actions: Upgraded reinforced gear pair and optimized flow channel structure reduce hydraulic pulsation and impact. The compound actions of slewing, lifting and digging of medium-large excavators are coherent and powerful, improving construction efficiency in mixed complex working conditions.
  • Cost-Effective Upgrade, No Performance Redundancy: Compared with the full mine-grade RMF148, RMF147 has more reasonable parameter matching and lower comprehensive cost, avoiding unnecessary performance waste for non-extreme mining conditions. It is the most cost-effective steady upgrade scheme for 18–22 ton mainstream construction excavators.
  • 1:1 OEM Lossless Replacement, Low Maintenance Cost: Standard universal OEM interface supports plug-and-play lossless upgrade without pipeline modification. It effectively repairs the aging hydraulic performance of old transition-tonnage excavators, restoring stable and sensitive original factory control feel.

FAQ

  • Q1: Full-series gradient positioning of RMF147?
  • 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) → RMF147(18–22t Transition Heavy-Duty) → RMF148(20–30t Mine-Grade Super-Heavy Duty). RMF147 is the exclusive transition heavy-duty model connecting ultra-high pressure earthwork and super-heavy mine grades.
  • Q2: What models is RMF147 suitable for?
  • A: It is specially applicable to 18–22 ton medium-large excavators that frequently switch between earthwork and medium rock-breaking working conditions, perfectly solving the adaptation dilemma of insufficient pressure of SBS series and redundant cost of RMF148 for transition tonnage equipment.
  • Q3: Core differences between RMF147, SBS140 and RMF148?
  • A: SBS140: 16–20t pure earthwork ultra-high pressure, weak anti-impact for rock breaking; RMF147: 18–22t mixed working condition transition type, balanced high pressure and impact resistance, cost-effective; RMF148: 20–30t full mine super-heavy duty, extreme pressure and impact resistance for harsh mining conditions.
  • Q4: Is installation lossless and universal?
  • A: Yes. RMF147 fully replicates OEM standard installation size, spline and interface, supporting direct plug-and-play replacement without cutting or modifying pipelines, zero installation error.
  • Q5: Daily maintenance specification for RMF147?
  • A: Use standard high-quality anti-wear hydraulic oil for large excavators, replace filter elements regularly to ensure oil cleanliness. Keep the pilot pressure stable at 29–34bar. Avoid long-term extreme overload mining operation beyond product positioning to extend service life.
