Short Description:

The HGP32.0 pilot pump is a high-precision factory-original hydraulic gear pilot pump widely used for 3–6 ton mini excavators, perfectly compatible with mainstream compact excavator models such as Kubota KX135, KX155, KX161, Takeuchi TB160, TB175 and various domestic 3–6 ton mini diggers.

description

The HGP32.0 pilot pump adopts a miniaturized precision compact reinforced gear pump structure, professionally optimized for low-pressure, ultra-small flow, long-term light-load continuous operation and frequent micro-action switching characteristics of 3–6 ton mini excavator hydraulic systems. Different from ordinary universal gear pumps with poor low-pressure stability, easy pressure fluctuation and high internal leakage, this model strictly follows original factory supporting standards, with fully standardized mounting hole positions, shaft diameter and installation dimensions, achieving ultra-low internal leakage and linear stable flow-pressure output under long-term light-load cyclic operation. Equipped with micro-precision wear-resistant alloy gear pair, low-load anti-fatigue bearing assembly and low-temperature aging-resistant composite sealing system, it maintains stable low-pressure pilot output without performance attenuation after long-term frequent micro-operation switching. The integrated ultra-compact high-rigidity pump body features outstanding vibration resistance, dust resistance and sediment corrosion resistance, fully adapting to narrow and fine construction environments such as municipal micro-renovation, garden engineering and indoor demolition.

advantages

  • Professionally calibrated for 3–6 ton mini excavator hydraulic systems, perfectly matching original miniature installation size and low-pressure pilot parameters, supporting 1:1 non-destructive plug-and-play replacement for Kubota, Takeuchi and domestic mini diggers, no modification required, 100% system matching with zero adaptation errors.
  • Adopting ultra-small-flow low-pulsation constant-pressure output technology exclusive for mini excavator low-pressure systems, it effectively stabilizes low-pressure fluctuation and slight pressure drop caused by frequent micro-actions and long-term light-load operation, thoroughly solving common pain points such as insensitive fine operation, weak trimming power and walking creeping of small mini excavators.
  • Micro-precision alloy gear pair and low-load anti-fatigue bearing structure optimize light-load wear resistance and micro-control stability, adapting to long-term continuous fine cyclic operation of mini excavators, maintaining stable low-pressure output without micro-control fatigue or performance attenuation.
  • Premium low-temperature resistant anti-aging composite sealing system adapts to outdoor cold and high-temperature alternating environments, effectively preventing slight oil leakage and low-pressure system pressure loss, reducing daily minor faults and routine maintenance frequency of mini hydraulic equipment.

FAQ

  • Q1: What are the common failure symptoms of HGP32.0 pilot pump?
  • A: Typical faults include insensitive micro-operation response, weak fine trimming and compound actions, unstable idle low pilot pressure, walking creeping and slight deviation, unsmooth swing rotation, slow main pump micro-variable response, minor pump body oil leakage and faint light-load abnormal noise.
  • Q2: Why do 3–6 ton mini excavators have inaccurate fine trimming?
  • A: Long-term frequent micro-action switching and light-load cycle operation cause minor wear of internal micro-precision gears and bearings, increased slight internal leakage and decreased low pilot pressure, resulting in delayed hydraulic response and insufficient fine-tuning power. Replacing the aging HGP32.0 pilot pump can restore original factory micro-control accuracy.
  • Q3: How to maintain HGP32.0 pilot pump daily?
  • A: Keep the mini hydraulic system oil highly clean, regularly replace hydraulic oil and miniature fine filter elements to prevent tiny dust and sediment impurities from wearing internal precision components. Regularly check pump body for oil leakage and abnormal noise to ensure stable low-pressure pilot output and sensitive micro-operation.
  • Q4: How to extend the service life of HGP32.0 pilot pump?
  • A: Avoid long-term continuous light overload and frequent sudden micro-load impact, keep the hydraulic system clean, reduce micro-wear and fatigue loss of internal precision parts, and effectively extend the service life of the miniature pilot pump.
