description

The GM35VA hydraulic pump adopts industrial-grade VA-series high-precision variable axial plunger structure, featuring more accurate pressure control and stronger low-temperature stability compared with conventional large-displacement VL pumps. The core cylinder block and piston shoe friction pair are processed by ultra-precision mirror grinding and integral vacuum quenching, with ultra-low wear rate and excellent anti-pollution adaptability, effectively restraining internal leakage and pressure fluctuation caused by long-term hard rock impact and low-temperature construction. The upgraded reinforced integrated swash plate and high-precision closed-loop variable control system realize micro-adjustment of flow and pressure under variable load conditions, solving the problems of walking drifting, working device jitter and inconsistent compound action linkage of old 30-35 ton excavators under heavy load. The optimized low-resistance heavy-duty bearing system and integral shock-absorbing structure reduce operating vibration and abnormal noise during long-term continuous operation.

advantages

  • VA Precision Pressure Regulation, Stable Heavy-Load Operation: Adopts exclusive VA high-precision variable regulation logic, different from conventional large-flow pumps. It features ultra-small pressure fluctuation under variable load, effectively solving heavy-load speed drifting and jitter problems, keeping the whole machine operating smoothly during long-term mine hard rock operation.
  • Ultra-Low-Wear Mirror Friction Pair, Durable Stability: The forged cylinder block and high-precision alloy piston shoe are mirror-polished and vacuum-quenched, with far lower wear rate than ordinary pump bodies. It restrains internal leakage growth caused by long-term hard impact and ensures consistent pressure and flow output in the whole service cycle.
  • Excellent Low-Temperature Adaptability, All-Weather Construction: Optimized wide-temperature sealing system and low-resistance variable structure realize stable startup and sensitive response in low-temperature environments, solving the failure of slow variable action and easy oil leakage of old pumps in winter low-temperature construction.
  • Reinforced Anti-Distortion Structure, Anti-Fatigue & Noise Reduction: Integrated thickened swash plate and heavy-duty bearing assembly resist frequent load impact and long-term continuous operation fatigue, reduce pump body resonance and abnormal noise, and improve overall equipment stability.
  • Strict Full-Factory Testing, Reliable Performance: Each GM35VA pump passes low-temperature startup test, full-range variable precision calibration, full-pressure durability aging and heavy-load impact simulation, ensuring stable and reliable performance for all-weather complex working conditions.

FAQ

  • Q1: What is the difference between GM35VA and GM35VL?
  • A: GM35VL focuses on super-large flow and extreme heavy-load stripping, suitable for large earthwork and high-intensity mining stripping; GM35VA focuses on precise voltage stabilization and low-fluctuation operation, more suitable for hard rock breaking, precise trenching and low-temperature all-weather working conditions, with better pressure stability and low-temperature performance.
  • Q2: What core faults can GM35VA solve?
  • A: It mainly solves typical faults of old 30-35 ton excavators: unstable heavy-load pressure, walking drifting, working device jitter, slow variable response, easy high-temperature pressure loss, low-temperature startup failure and intermittent oil leakage.
  • Q3: Is modification or debugging required for installation?
  • A: No modification and parameter debugging are required. Standard universal interface supports 1:1 plug-and-play direct replacement, which is completely compatible with the original hydraulic system of 30-35 ton large excavators.
  • Q4: Which working conditions is GM35VA more suitable for?
  • A: It is preferentially suitable for hard rock breaking, precise foundation excavation, low-temperature field operation and long-term precise compound operation; it is the preferred upgraded model for scenarios requiring high operational stability and low fluctuation.
  • Q5: Daily maintenance tips for GM35VA?
  • A: Keep hydraulic oil clean and replace filter elements regularly; avoid long-term extreme full-load impact; pay attention to oil temperature control in high-temperature seasons and preheating startup in low-temperature seasons to maintain long-term precise variable performance.
