Case Studies
Case 1: Shortened life of seal unit

Consultation from customers
We were asked to check the manufacturing site to see if there were any problems as the seal unit's lifespan was shortening.

Tanken Services
An on-site investigation revealed that the sealant flow rate supplied to the mechanical seal unit was improperly adjusted. After making the appropriate adjustments, the life of the seal unit was restored.

Guest Reviews
They came to the site to investigate and seriously investigated the cause, which was very helpful. Their technical skills and responsiveness are excellent.
Case 2: Leakage problem during actual operation

Consultation from customers
Although no problems were found during an airtight test of the seal unit alone before it was incorporated into the equipment, we were asked to check because leaks occurred immediately after installation.

Tanken Services
An on-site investigation revealed that the cause was old equipment that had caused a large thrust movement. After the problem was fixed, the equipment is now operating normally.

Guest Reviews
We are grateful for the accurate investigation of the cause on-site. They are excellent servicemen who are familiar with not only mechanical seals but the entire equipment.
