Whether you need bulk orders or special specifications, we help reduce your procurement costs and shorten delivery cycles, improving your supply chain efficiency.
3. Professional Engineering Support for Performance Optimization
Our skilled engineering team offers expert assistance in optimizing excavator hydraulic systems, extending component service life, and minimizing operational downtime. This leads to higher productivity and a lower total cost of ownership (TCO) for your fleet.
1. Product Quality Depends on Outsourced Manufacturing
The quality and performance of excavator parts from major brand owners such as Caterpillar, Komatsu, SANY, Doosan, Hitachi, Volvo, JCB, and John Deere often rely heavily on their OEM partners’ technical capabilities. This outsourcing can lead to risks of quality fluctuations, especially when supply chains become diversified and complex.
2. High Brand Premium and Elevated Procurement Costs
Brand owner typically charge a significant premium for excavator parts, resulting in higher procurement costs for buyers. While strong after-sales support and brand reputation are advantages, the overall investment required can be substantial, impacting project budgets and fleet maintenance costs.
3. Limited Flexibility and Slower Response Times
Brand owners focus on standardized customer management and broad market services, which may result in slower response times and less personalized technical support. For urgent or specialized loader parts needs, this can negatively affect operational efficiency and equipment uptime.
Not sure which type fits your market? Our team will help you choose the best solution based on your specific requirements.

FAQs
Cause:
Wrong rotation direction (gear pumps are divided into left/right rotation);
Oil filter is blocked or oil level is too low;
Oil temperature is too low, resulting in abnormal viscosity.
Solution:
Check that the motor direction is consistent with the direction marked on the pump body;
Clean or replace the filter element to ensure that the oil level in the tank meets the standard;
Select oil with appropriate viscosity or heat the oil temperature according to the season.
Cause:
Internal wear (such as excessive axial/radial clearance);
Leakage caused by overflow valve failure or oil contamination;
Air leakage on the suction side or excessive pipeline resistance.
Solution:
Replace worn gears, side plates or sleeves;
Clean or replace the overflow valve, and use hydraulic oil with a cleanliness standard (filtration accuracy ≤60μm);
Check the sealing and optimize the diameter and length of the suction pipe.
Cause:
Wrong rotation direction causes high-pressure oil to impact the oil seal;
Axial/radial force is too large (installation coaxiality deviation);
Seal material is mismatched or aged.
Solution:
Ensure the pump is rotating correctly and use an oil seal with a pressure resistance of ≥0.5MPa;
Adjust the installation coaxiality of the coupling (error ≤0.1mm);
Select oil-resistant seals such as nitrile rubber (NBR) and replace them regularly.
Cause:
Insufficient oil suction (filter element blockage, low oil level or pipeline leakage);
The oil viscosity is too high or contains bubbles;
Bearing damage or insufficient gear meshing accuracy.
Solution:
Clean the oil suction line and ensure the oil tank liquid level;
Replace the oil with appropriate viscosity and remove the air;
Replace the bearing or return to the factory to calibrate the gear accuracy.
Key measures:
Regular maintenance: replace filter elements and oil every 500 hours, and check the status of seals;
Select high-quality spare parts: such as original seal kits (such as KFP51 nitrile rubber kits);
Optimize working conditions: control oil temperature (≤80℃) and system pressure (≤90% of rated value).
Verification process:
Bench test: check whether the pressure, flow and noise meet the standards;
Load test: simulate actual working conditions for 30 minutes, monitor temperature rise and leakage.
Warranty service:
Professional repair shops (such as Permco) provide a 1-year warranty, covering parts replacement and labor costs.
Selection points:
Flow and pressure: Calculate the displacement based on the cylinder thrust (F=P×A) and speed;
Fluid compatibility: Mineral hydraulic oil (viscosity 16-80cSt) is preferred, avoid using highly polluted media;
Installation environment: Self-priming height ≤500mm, avoid high temperature or excessive vibration.
