Mechanical seals, NIPPON PILLAR PACKING Co.,Ltd.

The Pillar cassette seal was adopted the knife edge seal(*1) to the seal surface, which reduced the power consumption, making it possible to reduce the running cost.
Since this mechanical seal is applicable to a wide range of fluids ranging from fresh water to chemical fluid and slurry liquid, it is possible to integrate the type. This mechanical seal will not require any experience, as it can be installed by four actions.

*1) Mechanical seal of which seal end surface is formed to sharp-knife edge shape at one side.

■Features

◆ Adoption of knife edge seal
Since the knife edge seal has a limited seal surface width, the sliding torque is reduced and the power consumption is decreased, making it possible to reduce the running cost.
◆ Applicable to wide-range of fluids
Since the mechanical seal provides a limited seal surface width and a high surface pressure, it serves to prevent the high-viscosity fluid or coagulative fluid from being caught by the seal surface, assuring the excellent sealing performance by cutting and removing such coagulant.
◆ No experience required for installation
1.Insert the Pillar cassette seal into the shaft.
2.Fix the flange to the stuffing box.
3.Fixing to the shaft with set screw
4.Remove the set claw.
With the above steps, installation is completed.
Unlike the installation of conventional seal, it is not necessary to execute such works as to adjust the seal installation position, or to clean the seal end surface, etc.
