Shaft sealing device "Pillar Live Seal Unit No. 6300"

Shaft sealing device "Pillar Live Seal Unit No. 6300"

Are you having trouble with the shaft seals of mixers (kneaders), blenders, and dryers? It will bring stability to plant operations!

The "Pillar Live Seal Unit No. 6300" is a spring-pressurized shaft sealing device for low-speed rotating machinery. The live seal unit, designed and selected specifically for each piece of equipment, achieves proper tightening simply by tightening until the gap between the spring collar and the packing holder is zero, both during initial tightening and when re-tightening. No special tools are required. Additionally, the reduction in packing tightening force that can lead to leaks and the timing for re-tightening can be confirmed by measuring the gap dimensions. 【Features】 ■ Achieves maintenance-free operation with a gland packing and spring ■ Suitable for powder seals (dry seals) ■ Capable of maintaining stable sealing performance in response to shaft runout * For more details, please refer to the PDF document or feel free to contact us.

Non-water injection, non-lubrication mechanical seal 'T-Y SEAL FL'

Non-water injection, non-lubrication mechanical seal 'T-Y SEAL FL'

No water injection system is needed for lubrication and cooling!

Our company manufactures and sells the water-free and oil-free mechanical seal 'T-Y SEAL FL'. By eliminating the need for water injection and using materials with excellent sliding characteristics, we reduce the heat generation at the sliding parts, and the air cooling effect of the rotating ring cone enhances heat dissipation. The adhesion of the sealing surface is strengthened, minimizing the intrusion of slurry, which makes it less likely for issues to occur, allowing for stable operation over an extended period. 【Features】 ■ The water injection system for lubrication and cooling is omitted, making maintenance easier. ■ The time for sludge dewatering can be shortened. ■ Problems such as blockage, corrosion, and freezing of the water injection line can be resolved. ■ The condition of the seal can be visually checked even during operation. ■ Wear parts can be replaced without disassembling the pump, as they are in two parts. *For more details, please download the PDF or feel free to contact us.
