description

The A8VO107 pilot pump adopts upgraded precision reinforced gear pump structure, professionally optimized for the medium-pressure, medium-flow, long-term continuous operation and frequent variable-load switching characteristics of Rexroth A8VO107 main pump supporting 20–25 ton excavators. Different from ordinary universal pilot pumps with poor matching accuracy and unstable positive flow pressure control, this model strictly follows Rexroth original supporting standards, with fully standardized mounting dimensions and accurate hydraulic calibration parameters, achieving ultra-low internal leakage and linear stable flow-pressure output under long-term medium-heavy load operation. Equipped with high-precision wear-resistant alloy gear pair, anti-fatigue reinforced bearing assembly and imported high-temperature aging-resistant composite sealing system, it can maintain stable pilot pressure output without performance attenuation under long-term cyclic hydraulic impact and high-frequency compound action switching. The integrated high-rigidity pump body features outstanding vibration resistance, dust resistance and sediment corrosion resistance, fully adapting to complex medium-heavy load construction environments.

advantages

  • Professionally calibrated for Rexroth A8VO107 positive flow hydraulic system, perfectly matching original installation size and pilot pressure parameters, supporting 1:1 non-destructive plug-and-play replacement for 20–25 ton excavators with A8VO107 main pump, no equipment modification required, 100% system matching with zero adaptation faults.
  • Adopting medium-flow low-pulsation constant-pressure output technology exclusive for positive flow systems, it effectively stabilizes pilot pressure fluctuation caused by frequent compound action switching and medium-heavy load operation, thoroughly solving common problems such as slow response, weak digging power and walking jitter of medium and large excavators in daily construction.
  • High-precision alloy gear pair and reinforced anti-fatigue bearing structure improve overall wear resistance and operational stability, adapting to long-term continuous medium-heavy load operation of 20–25 ton excavators, maintaining stable pilot pressure output without performance attenuation or operation fatigue.
  • Premium anti-aging and high-temperature resistant composite sealing system resists long-term hydraulic cyclic impact and temperature changes, completely eliminating oil leakage and system pressure loss, effectively reducing daily equipment failure rate and maintenance costs.

FAQ

  • Q1: What are the common failure symptoms of A8VO107 pilot pump?
  • A: Typical faults include slow medium-heavy load operation response, weak boom/arm/bucket compound digging actions, unstable idle pilot pressure, walking jitter and deviation, sluggish swing rotation, insensitive main pump variable adjustment, pump body oil leakage and abnormal operating noise under load.
  • Q2: Why do 20–25 ton excavators with A8VO107 main pump operate sluggishly after long working hours?
  • A: Long-term medium-heavy load operation and frequent load switching cause wear of internal precision gears and bearings of the pilot pump, increased internal leakage and decreased pilot pressure, resulting in delayed main pump variable response and insufficient hydraulic power. Replacing the aging A8VO107 pilot pump can restore original control performance.
  • Q3: How to maintain A8VO107 pilot pump daily?
  • A: Keep the medium-flow hydraulic system oil clean, regularly replace hydraulic oil and filter elements to prevent hard impurities from wearing precision internal components. Regularly check the pump body for oil leakage and abnormal noise to ensure stable pilot pressure output and sensitive main pump variable operation.
  • Q4: How to extend the service life of A8VO107 pilot pump?
  • A: Avoid long-term continuous overload operation and frequent sudden load impact, maintain hydraulic system cleanliness, reduce internal component wear and fatigue loss, and effectively extend the service life of the pilot pump.
