Service features

1. Wide range of applications
- We pride ourselves on our wide range of services and our ability to respond quickly. We go beyond simple equipment repairs to offer preventive maintenance solutions that help our customers reduce operating costs and extend the life of their equipment.
2.Speedy response
- Our sales staff, who are knowledgeable and experienced construction specialists, will respond quickly to customer inquiries and minimize equipment downtime.
- Because we can supply our own workers and in-house manufactured mechanical seals, in the event of an emergency involving a large pump leak, we can restore the equipment with a rapid response that cannot be matched by other companies.
This quick response time has led to more customers choosing repair over replacement.
3.High-quality service
- We can propose improvements to the conditions around the shaft seal, based on our experience and knowledge gained not only in buildings, but also in oil refineries, chemicals, pharmaceuticals, food, water and sewage facilities, etc. In addition, we can provide maintenance estimates that are suited to each customer by proposing the reuse of parts that do not necessarily need to be replaced.
Case Studies
Case 1: Extension of maintenance period for heat transfer water pump

Consultation from customers
Even if the heat transfer water pump is maintained, leakage will occur within a year.

Tanken Services
By selecting a mechanical seal that matched the pump specifications and carrying out appropriate pump maintenance, there have been no further leaks even after three years.

Guest Reviews
Before we asked Tanken to help us, we had many leaks in a short period of time, and we had to pay maintenance costs each time, so we are very grateful.
Case 2: Emergency maintenance of hot water pump

Consultation from customers
The pump is leaking heavily, but if we ask another company to do the work, they will not be able to procure the parts, and they said it will take six months to complete the work. Since the pump is important, I would like it repaired as soon as possible.

Tanken Services
We were able to secure parts for repairing the existing mechanical seal and producing a new packing in-house, and the pump was restored to working order in about a week.

Guest Reviews
We are extremely grateful for this, as stopping this pump would cause significant damage.
