description

The PSVD2-17E variable piston pump adopts a miniaturized high-precision swash plate variable structure, specially optimized and calibrated for low-load, high-frequency and fine-operation working conditions of 1.5–2 ton micro excavators. It maintains a rated working pressure of 245bar and a peak pressure of 280bar, with stable pressure resistance and impact tolerance that fully meet the fine excavation and municipal miniature construction demands of micro-excavators. The miniaturized high-density cylinder block, ultra-fine polished piston assembly and low-friction valve plate are made of high-grade wear-resistant alloy materials, matched with micro-gap dynamic self-compensation technology. It ensures volumetric efficiency ≥95% and mechanical efficiency ≥92% under long-term light and medium-load cyclic operation, with almost no performance attenuation. Equipped with original precision pressure feedback load-sensing variable system, it dynamically adjusts flow and pressure according to micro-load changes, realizing ultra-sensitive micro-operation, coordinated compound actions and stable low-speed walking.

advantages

  • 17ml/r Ultra-Small Displacement, Exclusively for Micro Excavators: The exclusive 17ml/r ultra-small displacement is precisely calibrated for 1.5–2 ton micro excavators, avoiding power redundancy and high idle fuel consumption of large-displacement pumps. It provides matched power reserve for fine earthwork and narrow-space operation, making construction more energy-saving and efficient.
  • Precision Load-Sensing Variable, Sensitive Micro Operation: Adopting upgraded miniature load-sensing variable technology, the pump responds quickly to tiny load changes. Micro-excavation, trimming and compound actions are smooth and accurate without jitter or lag, greatly improving fine construction quality.
  • Stable Low-Speed Performance, No Crawling: Optimized low-friction internal matching structure effectively solves the common problems of low-speed crawling and unsteady walking of old micro pumps. The whole machine runs smoothly at low speed, with uniform flow output and stable operation.
  • Lightweight Heat Dissipation, Anti High-Temperature Attenuation: The customized lightweight circulating heat dissipation structure targets the long-term low-load continuous operation characteristics of micro-excavators. It quickly dissipates internal heat and prevents power drop and performance drift caused by temperature rise.
  • Original Standard Interchangeability, Low Maintenance Cost: Fully compliant with OEM original installation dimensions and hydraulic parameters, supporting plug-and-play direct replacement. It shortens maintenance downtime and reduces long-term operation and replacement costs for micro-excavator users.

FAQ

  • Q1: What equipment does the PSVD2-17E pump fit for?
  • A: PSVD2-17E is a dedicated main hydraulic pump for 1.5–2 ton ultra-small mini excavators, widely compatible with mainstream micro digger models in the market. It is the standard matching power component for miniature engineering hydraulic systems.
  • Q2: What are the core advantages of PSVD2-17E compared with ordinary micro pumps?
  • A: It features higher micro-control accuracy, more sensitive load response and lower idle fuel consumption. The low-speed jitter and high-temperature attenuation problems of ordinary micro pumps are completely optimized, with more stable overall performance and longer service life.
  • Q3: Why do micro excavators need a dedicated 17ml/r small displacement pump?
  • A: Micro-excavators focus on fine and low-load operation. Large-displacement pumps will cause power redundancy, high fuel consumption and unsmooth micro-operation. The 17ml/r PSVD2-17E can perfectly match the power demand of micro-excavators, balancing efficiency and energy saving.
  • Q4: What faults indicate the need to replace PSVD2-17E?
  • A: Replace the pump when the micro-excavator has weak fine excavation, unsmooth compound actions, obvious low-speed jitter, increased idle fuel consumption and power attenuation after long-hour operation.
  • Q5: Daily maintenance tips for PSVD2-17E hydraulic pump?
  • A: Use clean anti-wear hydraulic oil for micro-excavators, replace filter elements regularly to prevent tiny particle wear; avoid long-term high-speed no-load operation; regularly check oil circuit and oil seal tightness to ensure stable micro-operation performance.
