description

The HPK055 hydraulic pump adopts industrial-grade PK-series lightweight high-sensitivity adaptive variable axial plunger structure, comprehensively optimized for the fine operation and frequent start-stop working characteristics of 5-6 ton mini excavators. It abandons the bulky low-slag structure of traditional light-duty pumps, achieving perfect balance of compact layout, sensitive response and low energy consumption. The core cylinder block and piston shoe friction pair adopt miniaturized precision forging and ultra-fine mirror grinding process, matched with low-stress overall tempering treatment, with ultra-low starting resistance and excellent low-speed follow-up performance. It effectively solves the problems of slow starting, unsmooth micro-operation and poor precision control of old mini excavators during fine construction. The exclusive PK high-sensitivity electronic control variable system supports millisecond-level flow and pressure adjustment, automatically matching low-load fine trimming and conventional earthwork excavation working conditions, eliminating invalid power output and significantly reducing daily fuel consumption.

advantages

  • Exclusive PK High-Sensitivity Fine Control, Zero Lag Micro Operation: Different from heavy-duty impact-resistant series pumps, HPK055 focuses on fine construction performance. It adopts exclusive PK high-response closed-loop adjustment logic, realizing instantaneous follow-up of small flow and micro pressure changes, completely solving the lag and jitter problems of old mini excavators during fine trimming and urban renovation.
  • Lightweight Low-Resistance Structure, Significant Idle Energy Saving: Miniaturized precision forged cylinder block and low-friction silent piston shoe reduce invalid mechanical loss during frequent start-stop and idle operation. The idle fuel saving rate is significantly improved, perfectly matching the long-hour low-load operation characteristics of urban small-scale engineering.
  • Low-Temperature Anti-Aging Sealing, Stable Four-Season Operation: Equipped with upgraded low-temperature resistant silent sealing kits, it solves the problems of difficult cold start, slow pressure build-up and micro leakage of ordinary light-duty pumps in low-temperature environments, ensuring stable operation in all seasons.
  • 1:1 Lossless Plug-and-Play Replacement, No On-Site Debugging: Mini standard flange and oil port positioning design fully matches the original hydraulic parameters of 5-6 ton mini excavators. No pipeline modification or parameter calibration is required, reducing maintenance time and equipment downtime.
  • Precision Calibration Testing, Stable Fine Operation Performance: Each HPK055 pump passes micro-action sensitivity calibration, idle energy-saving test and low-temperature adaptation detection. The overall performance is more delicate and stable than ordinary light-duty pumps, fully adapting to high-precision construction requirements of small urban projects.

FAQ

  • Q1: What is the core positioning of HPK055 in the full series? A: The HPK055 is the light-duty high-precision silent energy-saving flagship model of the full HM/HMG series, exclusively developed for 5-6 ton mini excavators. It focuses on fine operation sensitivity and urban energy-saving silent construction, filling the performance gap of small-tonnage high-precision pumps in the series.
  • Q2: What core faults can HPK055 solve? A: It targets common faults of 5-6 ton mini excavators: insensitive micro action response, jitter in fine compound operation, high idle fuel consumption, loud working noise, weak low-speed torque and seasonal micro oil leakage of old pumps.
  • Q3: Is parameter debugging or pipeline modification required after installation? A: No modification and debugging are required. The HPK055 is factory pre-calibrated with small-tonnage fine operation parameters, supporting 1:1 lossless plug-and-play replacement, fully compatible with the original hydraulic system of 5-6 ton mini excavators.
  • Q4: What scenarios is HPK055 most suitable for? A: It is specially suitable for urban narrow-space fine construction, foundation trenching, garden renovation, indoor demolition, residential area silent operation and frequent start-stop low-load trimming work.
