description

The A10VSO28 variable piston pump adopts an optimized reinforced 31-series swash plate variable structure, comprehensively upgraded for medium-heavy load continuous operation conditions. It inherits the mature low-loss oil circuit design of the A10VSO series and expands the internal flow channel specification, achieving larger effective flow output and stronger pressure impact resistance. The pump features a rated working pressure of 280bar and a peak pressure up to 350bar, with reliable high-pressure bearing capacity for long-term heavy-load pressure holding and variable load impact working conditions. Core components including thickened piston assembly, high-density forged cylinder block and nano-precision lapped valve plate are made of high-strength wear-resistant alloy materials, matched with multi-stage gap adaptive calibration technology, ensuring volumetric efficiency ≥96% and mechanical efficiency ≥93% under full-load variable operation. It supports mainstream DFR pressure-flow compound control and DRG remote hydraulic control modes, with faster load response speed and more accurate flow and pressure matching than small-displacement models.

advantages

  • 28ml/r Mid-Flow Upgrade, Sufficient Heavy-Load Power Reserve: Upgraded 28ml/r large-displacement design compared with A10VSO18, effectively solving the problem of insufficient flow and weak power of small pumps under medium and heavy load conditions. It provides stable and surplus power support for medium-sized engineering and heavy industrial hydraulic systems, realizing perfect matching of heavy-duty operating power.
  • 280bar Rated High Pressure, Strong Impact & Pressure Resistance: Adopting industrial high-pressure structural standard, with 280bar rated pressure and 350bar peak pressure. It stably copes with instantaneous pressure impact, long-term high-pressure holding and heavy-load variable load operation, with far stronger comprehensive pressure resistance than small-displacement variable pumps.
  • Ultra-High Full-Load Efficiency, Zero Long-Term Performance Attenuation: The enlarged low-loss flow channel and precision alloy friction pair matching ensure ultra-high full-load operating efficiency. The heat dissipation and anti-aging structure are upgraded for heavy-load working conditions, maintaining stable flow and pressure output for a long time without obvious performance attenuation, ensuring consistent equipment operating efficiency.
  • Ultra-Wide Speed Adaptation, Strong Working Condition Compatibility: The 1450–4800rpm ultra-wide speed range adapts to high-frequency and variable-speed operating requirements of industrial automated equipment and medium construction machinery, with strong environmental adaptability and stable operation under complex cyclic working conditions.
  • Standard Universal Installation, Low Maintenance & Operating Cost: Fully compatible with original equipment installation dimensions and hydraulic parameters of mainstream medium-flow hydraulic systems. Plug-and-play direct replacement shortens maintenance downtime, reduces failure rate caused by insufficient power of old pumps, and lowers long-term equipment operating cost.

FAQ

  • Q1: What equipment and working conditions is the A10VSO28 suitable for?
  • A: The A10VSO28 medium-flow high-pressure variable pump is mainly applicable to medium-sized construction machinery, heavy-duty industrial hydraulic stations, injection molding machinery and automated production lines. It is specially used for medium and heavy load open-circuit hydraulic systems, suitable for long-term high-pressure holding and high-frequency cyclic continuous operation scenarios.
  • Q2: What is the core difference between A10VSO28 and A10VSO18?
  • A: A10VSO18 is a small-flow pump for light-load auxiliary and low-power main systems; A10VSO28 is an upgraded medium-flow model with larger flow reserve, stronger heavy-load resistance and higher working efficiency. It is suitable for medium-heavy load main hydraulic systems where A10VSO18 is insufficiently powered.
  • Q3: What control modes does A10VSO28 support?
  • A: It supports two mainstream industrial control modes: DFR pressure-flow compound control for synchronous precise matching of pressure and flow; DRG remote hydraulic control for remote stepless variable regulation, meeting the automatic control requirements of different industrial and engineering equipment.
  • Q4: When does the equipment need to be replaced with A10VSO28?
  • A: If the original small-displacement pump has problems such as insufficient heavy-load power, slow load response, obvious flow attenuation during long-term continuous production, unstable pressure and high energy consumption, replacing with A10VSO28 can effectively upgrade system power and restore stable high-efficiency operation.
  • Q5: What are the key maintenance points for A10VSO28?
  • A: Use high-grade industrial high-pressure anti-wear hydraulic oil, replace filter elements regularly to ensure oil cleanliness; avoid long-term overload and overpressure operation; regularly inspect the variable valve group, sealing components and heat dissipation system to prevent internal leakage and high-temperature aging, ensuring long-term heavy-load stable output.
