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.
