Problems with high-pressure ammonium pump
Thread Content
I have a problem: the O-ring located behind the rotating ring of the oil seal in the urea ammonium pump keeps leaking oil. Every time the seal is replaced, the leakage occurs again after a short period of time. The medium seal and the water seal are working fine. What could be the cause? The pump is manufactured by Stain
It is possible that there is a seizure between the O-ring of the mechanical seal and the shaft sleeve, causing the O-ring to wear out excessively and resulting in oil leakage. It is recommended to check whether there is any wear or scratches on the surface of the shaft sleeve; if necessary, the shaft sleeve can be replaced. Additionally, it is also worth considering replacing it with a high-quality O-ring to improve wear resistance. Since the pump is manufactured by Stäubli, you can contact Stäubli’s after-sales service for more detailed solutions. .
Inspect the O-ring for any abnormalities
