description

PVK-2B-505 hydraulic pump spare parts adopt targeted light-medium load optimization for 4–6 ton mini excavator working conditions. Core friction pair components adopt high-quality alloy steel matrix + dense uniform wear-resistant copper alloy composite structure, balancing flexible response, wear resistance and structural stability, fully adapting to high-frequency light-medium load cyclic operation of mini construction machinery. The cylinder block undergoes integral precision heat treatment and multi-cycle micro stress relief to eliminate processing residual stress and operational fatigue stress, matched with ultra-precision mirror lapping to form stable micron-level clearance fit with the valve plate, effectively restraining progressive internal leakage caused by long-term low-medium pressure continuous operation. The upgraded piston-shoe assembly adopts optimized lubrication grooves and smooth anti-friction structure, minimizing cyclic friction loss during frequent forward-reverse switching and light-load operation, maintaining stable low-speed torque output and smooth walking without stuttering or power attenuation. The reinforced valve plate and retainer plate optimize uniform contact stress distribution, comprehensively improving pressure resistance and structural fatigue resistance, completely solving stubborn faults such as low-speed crawling, walking deviation and intermittent jitter of 4–6 ton mini excavators. The high-rigidity integrated center shaft enhances torsion resistance and structural toughness, adapting to long-term alternating micro-load operation of urban and residential complex roads.

advantages

  • Light-Medium Load Optimized, Stable Torque Output: Core friction pairs adopt multi-cycle stress relief and alloy toughening technology, specially optimized for long-term 4–6 ton mini excavator frequent light-medium load operation. It effectively solves low-speed stuttering and insufficient walking power, maintaining stable torque output and sensitive hydraulic response without performance attenuation.
  • High Cost-Performance, Reduce Micro-Construction Downtime Loss: Support flexible single-piece replacement for local partial wear and full kit replacement for overall aging. Avoid expensive integral motor replacement, greatly reducing daily operation and maintenance costs and micro-construction shutdown losses of 4–6 ton mini excavators.
  • Full-Coverage Accessory System, One-Stop Overhaul: Completely covers core mid-displacement light-medium load rotating group wearing parts and low-medium pressure aging-vulnerable sealing components, fully adapting to daily maintenance, light-medium load fault repair and complete machine overhaul of PVK-2B-505 travel motors, realizing one-stop professional supporting maintenance for mini engineering equipment.
  • Multi-Process Strict Factory Inspection, Stable Batch Quality: Each batch of spare parts undergoes precision dimensional verification, flatness testing, hardness sampling and low-medium pressure cycle impact tests to ensure uniform batch quality, guaranteeing stable and durable light-medium load operating performance after equipment repair.

FAQ

  • Q1: What excavators does the PVK-2B-505 fit for?
  • A: The PVK-2B-505 hydraulic pump is specially designed for 5–6 ton medium compact excavators, compatible with multiple mainstream domestic and imported medium excavator models. It is the standard high-power large-displacement main pump for 5–6 ton excavator hydraulic systems.
  • Q2: What is the difference between PVK-2B-505 and PVD-2B-36?
  • A: PVD-2B-36 is a 36ml/r heavy-duty pump for 3–4 ton micro excavators; PVK-2B-505 adopts upgraded 50ml/r large displacement and higher pressure grade, with stronger rock excavation and continuous high-load operation capacity, specially used for 5–6 ton medium excavator high-intensity construction.
  • Q3: What working conditions is PVK-2B-505 suitable for?
  • A: It is ideal for high-intensity heavy-load scenarios including hard soil cutting, rock excavation, deep foundation trenching, long-term full-load continuous operation and frequent earth-stone mixed construction of 5–6 ton medium excavators.
  • Q4: When should I replace the PVK-2B-505 pump?
  • A: Replace the pump if the 5–6 ton excavator has weak rock excavation power, slow compound action response, obvious high-temperature power drop after long-hour heavy operation, and insufficient flow leading to reduced construction efficiency.
  • Q5: What are the daily maintenance tips for PVK-2B-505?
  • A: Use clean high-grade anti-wear hydraulic oil and replace filter elements regularly to avoid particle wear on precision components; avoid long-term extreme overload and sharp impact operation; regularly check sealing and heat dissipation conditions to prevent internal leakage and high-temperature performance attenuation.
