description

The AP2D18 variable piston pump adopts an optimized reinforced swash plate variable structure, specially upgraded for medium-light load continuous operation of 3–6 ton small construction machinery. It features a rated working pressure of 260bar and a peak pressure up to 300bar, with upgraded pressure resistance and impact tolerance compared with AP2D14. The thickened precision piston assembly, high-density forged cylinder block and nano-lapped valve plate are made of high-strength wear-resistant alloy, matched with micro-gap self-compensation technology, ensuring volumetric efficiency ≥95% and mechanical efficiency ≥92% under full-load operation. Adopting mature pressure feedback load-sensing variable mode, it can dynamically adjust flow and pressure according to working load changes, realizing accurate power matching, smooth action and low energy consumption. The optimized low-loss oil circuit and enhanced heat dissipation structure effectively suppress heat accumulation and performance attenuation during long-term high-frequency cyclic operation. It supports a wide speed range of 1450–4800rpm, adapting to frequent start-stop excavation operation and long-time steady working of small equipment.

advantages

  • 18ml/r Standard Displacement, Exact Matching for 3–6 Ton Machinery: The 18ml/r standard displacement perfectly solves the power bottleneck of AP2D14 on 3–6 ton equipment. It provides sufficient power for small-scale excavation and earthwork operations without the bulky volume and power waste of medium-sized pumps, achieving the best balance of power and volume.
  • 260bar High Pressure Resistance, Strong Impact Adaptability: Upgraded 260bar rated pressure and 300bar peak pressure, effectively coping with instantaneous impact pressure and medium-light load continuous pressure holding during small machinery construction. The pressure stability is significantly improved compared with lower displacement models.
  • Load-Sensing Intelligent Variable, Low Energy Consumption: Pressure feedback load-sensing variable system dynamically matches flow and pressure according to actual working conditions. It reduces invalid power loss under no-load and light-load conditions, effectively lowering equipment fuel consumption and improving operating economy.
  • Universal OEM Installation, Easy Replacement: Fully compatible with original equipment installation dimensions and hydraulic parameters, supporting plug-and-play direct replacement. It shortens maintenance downtime and quickly restores equipment working efficiency.

FAQ

  • Q1: What equipment is the AP2D18 suitable for?
  • A: The AP2D18 hydraulic pump is the standard main pump for 3–6 ton small excavators, also widely used in skid steer loaders, small road rollers and aerial work platforms. It is suitable for medium-light load, high-frequency cyclic small earthwork and foundation construction scenarios.
  • Q2: What is the difference between AP2D18 and AP2D14?
  • A: AP2D14 is a 14ml/r ultra-compact pump for 1–3 ton ultra-small equipment with pure light-load positioning; AP2D18 is an upgraded 18ml/r power version with higher pressure resistance and larger flow reserve, specially designed for 3–6 ton small excavator main hydraulic systems.
  • Q3: What variable mode does AP2D18 adopt?
  • A: It adopts pressure feedback load-sensing automatic variable mode, which independently adjusts flow and pressure according to load changes without external control valves, featuring simple structure and sensitive response.
  • Q4: When to replace the AP2D18 pump?
  • A: Replace the pump when the small excavator has weak digging power, slow compound action response, obvious pressure drop during load holding, increased noise and rising fuel consumption, to restore stable working performance.
  • Q5: How to maintain AP2D18 daily?
  • A: Use qualified anti-wear hydraulic oil, replace filter elements regularly to ensure oil cleanliness; avoid long-term overload operation; check sealing parts and oil circuit regularly to prevent internal leakage and high-temperature aging.
