Is there a master from Jingbo? Expansion oil station pump repair
Thread Content
The mechanical seal is leaking; after replacing it, there is an abnormal noise inside. What could be the cause?
Is it the pressure relief valve releasing pressure? Use it for a while to determine the cause of the abnormal noise. Or disassemble and reinstall it; it is best to contact the original manufacturer for technical support.
Why not ask the supplier of the gas station, or the manufacturer of the pump?
