The mechanical seal of the YAB15-5 liquid ammonia pump is leaking frequently; it’s a pump made by Boshan Kehai. I would appreciate it if experts could offer some suggestions. Thank you!

Describe the condition of the seal damage; is the bearing damaged?

Were there any dents or damages to the sealing surfaces during installation?

It would be best to describe the situation in detail

Where is the leakage coming from? Does it start leaking as soon as it’s installed and turned on, or does it begin leaking after some time? When opening the mechanical seal, are the O-rings as well as the stationary and rotating rings in good condition?
