Mechanical seals, NIPPON PILLAR PACKING Co.,Ltd.

The Pillar PEC seal is a non-contact type shaft sealing unit used to prevent the gas base fluid, etc.(which may adversely affect the environment) from contaminating the atmosphere.
It is used for shaft sealing of rotary units such as turbine, blower, compressor, agitator, etc.
Since the seal unit is designed for non-contact, it assures the cleanliness (non-generation of contamination) and energy-saving (limited power loss, etc.)

■Features

◆ Enhanced effect for prevention of atmosphere from contamination
Since the seal adopts such method as to supply the seal gas(having pressure higher than the internal pressure of equipment) from the outside, it is possible to seal the internal equipment gas, using the single seal, thus providing the effect for prevention of atmosphere from contamination.

◆ Free from contamination
Since the seal surface is designed for non-contact, the abrasion particle is not generated.
Consequently, this seal is best applicable to such plant as food, medicine, etc. where the cleanliness is required.

◆ Long life
Since the seal surface is designed for non-contact, the prolonged life is expectable without any wear and damage on seal surface.

◆ Energy-saving
Since the seal surface is designed for non-contact, this seal is an energy-saving type shaft sealing unit of which power loss is limited enough to be negligible.
