description

The AP2D25 variable piston pump adopts a fully upgraded reinforced heavy-duty swash plate variable structure, optimized for high-intensity medium-heavy load continuous operation of 6–9 ton construction machinery. It achieves a rated working pressure of 280bar and a peak pressure of 320bar, with comprehensively upgraded pressure resistance, impact tolerance and load stability compared with AP2D21. The thickened ultra-high precision piston assembly, integrally forged high-density cylinder block and super-finished nano valve plate are made of imported high-strength wear-resistant alloy. Combined with micro-gap dynamic self-compensation and anti-fatigue lubrication technology, it ensures volumetric efficiency ≥96% and mechanical efficiency ≥93% under long-term full-load heavy-duty operation, with negligible performance attenuation. Equipped with mature pressure feedback load-sensing variable system, it dynamically matches flow and pressure according to real-time load changes, realizing precise power distribution, sensitive action response and stable compound operation. The expanded low-loss flow channel and enhanced forced circulation heat dissipation structure effectively eliminate heat accumulation during long-hour high-load construction, solving common high-temperature power drop problems of small-displacement pumps.

advantages

  • 25ml/r Precision Large Displacement Upgrade, Perfect for 6–9 Ton Machinery: The exclusive 25ml/r displacement bridges the performance gap between AP2D21 and AP2D28. It provides sufficient flow and power reserve for hard soil and mixed earth-stone working conditions, completely solving the power shortage of smaller displacement pumps in heavy-load scenarios.
  • 280bar High Standard Pressure Resistance, Strong Impact Resistance: Upgraded 280bar rated pressure and 320bar peak pressure, far exceeding the pressure level of conventional small pumps. It stably resists instantaneous impact pressure and long-term overload holding pressure, ensuring stable operation in harsh construction environments.
  • Optimized Load-Sensing Variable, Higher Energy Efficiency: The upgraded pressure feedback variable system achieves more accurate power matching. It effectively reduces invalid power consumption under no-load and light-load conditions, lowering equipment fuel consumption while improving heavy-load working efficiency.
  • Forced Heat Dissipation Design, Zero High-Temperature Attenuation: Adopting active forced circulation heat dissipation technology, it quickly takes away internal heat generated by high-intensity operation. It avoids common faults such as high-temperature speed drop, power attenuation and oil aging of small-displacement pumps during long-hour continuous construction.
  • Compact and Versatile, Low Maintenance Cost: It retains the compact structural advantages of the AP2D series without redundant volume. Standard OEM installation supports quick plug-and-play replacement, shortening maintenance downtime and reducing long-term operating costs.

FAQ

  • Q1: What equipment is the AP2D25 suitable for?
  • A: The AP2D25 hydraulic pump is specially designed for 6–9 ton medium and small excavators, and also compatible with large skid steer loaders, road compactors and trenchers. It is ideal for heavy-load scenarios such as hard soil excavation, mixed earth-stone construction and long-term full-load continuous operation.
  • Q2: What is the difference between AP2D25 and AP2D21?
  • A: AP2D21 is positioned for conventional medium-load operation of 5–8 ton equipment; AP2D25 has larger displacement, higher pressure grade and stronger heat dissipation capacity, specially upgraded for frequent heavy-load and high-temperature working conditions of 6–9 ton excavators.
  • Q3: What variable technology does AP2D25 adopt?
  • A: It adopts upgraded pressure feedback load-sensing automatic variable technology, which dynamically adjusts flow and pressure according to load changes without external control valves, featuring sensitive response and stable power output.
  • Q4: When is it necessary to replace the AP2D25 pump?
  • A: Replace the pump when the equipment shows weak heavy-load excavation power, slow compound action, obvious high-temperature power drop, increased noise and rising fuel consumption, to restore full heavy-load working performance.
  • Q5: How to maintain the AP2D25 pump daily?
  • A: Use high-quality high-pressure anti-wear hydraulic oil, replace filter elements regularly to ensure oil cleanliness; avoid long-term extreme overload operation; regularly inspect the heat dissipation system and sealing parts to prevent internal leakage and high-temperature aging.
