Excavator Hydraulic Rotary Plunger Pump Repair Kit PC320 Hydraulic Machine Spare Parts
Excavator Hydraulic Rotary Plunger Pump Repair Kit PC320 Hydraulic Machine Spare Parts
Efficient maintenance solutions for excavator hydraulic pumps
Hydraulic rotary plunger pumps are the "power core" of excavators, driving key actions such as boom lifting, arm rotation, and bucket operation. After long-term operation in harsh environments-exposed to dust, vibration, and high pressure-internal components like plungers, seals, and valve plates are prone to wear, leading to reduced pump efficiency or oil leakage. The Excavator Hydraulic Rotary Plunger Pump Repair Kit for PC320 is engineered to address these issues, providing a complete set of replacement components to restore the pump's performance. As essential hydraulic machine spare parts, this kit includes precision-machined plungers, high-temperature seals, and wear-resistant valve plates, all tailored to the PC320 pump's specifications. The pc320 hydraulic spare is designed to match the original pump's dimensions, making it a reliable choice for quick and effective repairs.
Core advantage: Balancing maintenance efficiency and performance recovery
The pc320 hydraulic spare stands out for its ability to restore the PC320 pump's original performance. Each component in the kit is manufactured with strict adherence to OEM standards: plungers are ground to a surface roughness of Ra 0.02μm, ensuring tight fitting with the cylinder block and reducing internal leakage to less than 0.1 L/min. This precise fit not only improves the pump's volumetric efficiency (restored to over 94%) but also reduces abnormal wear, extending the pump's service life by 40% after repair. As hydraulic machine spare parts, they also simplify maintenance-technicians can replace all worn components in one repair, avoiding repeated disassembly and reducing downtime by 30% compared to replacing parts individually.
Another key advantage of the pc320 hydraulic spare is its adaptability to harsh working conditions. Seals in the kit are made of fluorinated rubber, which resists hydraulic oil corrosion and operates stably at temperatures ranging from -20°C to +120°C-critical for excavators working in cold winters or high-temperature construction sites. The hydraulic machine spare parts also include reinforced valve plates with a wear-resistant coating, which can withstand the continuous friction of plungers, ensuring long-term stable operation of the pump after repair.
Technical features: Tailor-made for PC320 pump maintenance
- Precision Component Matching: The pc320 hydraulic spare is engineered to match the PC320 pump's internal structure, with plunger length and valve plate thickness identical to the original parts. This ensures that after assembly, the pump's pressure and flow output meet the excavator's operational requirements.
- Comprehensive Repair Coverage: As hydraulic machine spare parts, the kit includes all vulnerable components-plungers, seals, springs, and oil distribution plates-eliminating the need to source parts separately and ensuring a one-stop repair solution.
- Easy Installation: Each component in the pc320 hydraulic spare is marked with installation guides, and the kit comes with a detailed assembly manual. Even for technicians with moderate experience, the repair process can be completed within 4 hours, minimizing excavator downtime.
- Durability Testing: The hydraulic machine spare parts undergo rigorous testing, including 5,000 cycles of pressure testing (up to 350 bar) and 1,000 hours of wear testing, ensuring they meet or exceed the original parts' performance standards.
