Miniature Electrodeposited Bellows (Servometer)

With the electroforming method, precise control of plate thickness is possible! Miniature size and flexible bellows!

The miniature bellows from Servometer are capable of achieving a very thin bellows plate thickness through an electrodeposition process, making them both "miniature-sized" and "highly flexible." They have a proven track record in applications where quality, reliability, and long lifespan are critical, such as metal sealing seals, volume compensators, pressure and temperature sensors, and flexible connectors. **Features** - Realizes high-sensitivity bellows through precise control of plate thickness via the electrodeposition process. - Ideal for applications requiring small loads for strokes and bending angles due to flexibility. - Allows for a larger inner diameter/outer diameter ratio, significantly increasing volumetric displacement capability. - No seams or permeability! Eliminates concerns about dust and debris that can cause contamination, while maintaining an extremely low leak level.

[Case Study] Two-Part Mechanical Seal That Can Be Installed Without Disassembling the Pump

Can be installed without disassembling the pump - 2-part mechanical seal.

In a factory using dozens of large circulation pumps for cooling water, frequent water leaks from the pumps were causing problems. These pumps used gland packing as the sealing material, but the seals were ineffective, leading to water leaks that soaked the surrounding area. The factory's production was busy, making it difficult to stop the pumps frequently, and the large number of pumps, along with the safety risks associated with tightening the packing and adjusting for leaks while the pumps were in operation, meant that these tasks were not being performed. 1. Increased loss of water and costs for recovery and cleaning. 2. Reduced lifespan and damage to bearings and pump failures due to water leaks. 3. Wear on the pump shaft caused by gland packing. 4. Adjustments to rotating equipment while in operation are not possible due to the risk of entanglement. 5. Maintenance requires extensive work using tow trucks and other equipment due to the size of the pumps. We received a consultation expressing a desire to reduce these tasks as much as possible.

Mechanical seal repair: Reduce costs by repairing instead of replacing!

Mechanical seals used in pumps and other equipment. In fact, they can be restored to a condition almost like new through repairs.

Many companies immediately consider purchasing a new mechanical seal when a malfunction occurs. However, it is not widely known that mechanical seals can be restored to nearly new condition through repairs. Furthermore, there is a significant price difference between purchasing a new one and opting for repairs, leading to considerable cost savings. Our repair service can also accommodate mechanical seals from other companies with a quick turnaround, so please feel free to consult with us.

[Case 1] Mechanical Seal Repair and Regeneration

[Case 1] Adoption case at a gas plant factory

Until now, the mechanical seals used in pumps needed to be replaced at a fairly rapid pace, and we had been replacing them with new ones each time, which incurred fixed costs. We decided to try having the discarded seals sent to our company for repair and regeneration, and it turned out that they could be used at a low cost and were as good as new. This has reportedly led to significant cost reductions.
