"What is a mechanical seal? What is it?" Let's explain that question! We will introduce the mysteries of sliding surfaces and more.

This document provides information about the first Mechanical Seal Beginner Course and will explain the question, "What is a mechanical seal?" A mechanical seal is a shaft sealing device that emerged at the end of the 19th century. It began as a military technology and has rapidly evolved alongside the advancement of various industries. Nowadays, it has become an essential component in the shaft penetration parts of various fluid devices such as pumps and agitators. It can seal fluid leaks stably over the long term.

"What is the difference from Grand Packing? What is it?" This question will be explained! We will introduce a thorough comparison and more.

This document contains information about the 14th Basic Mechanical Seal Course, and we will explain the question, "What is the difference from a gland packing?" Gland packing is a cord-like packing made of woven fibers. Multiple gland packings are housed in a stuffing box through which the shaft passes, and the gland is tightened with bolts to make contact between the shaft and the gland packing, creating a seal. To prevent the gland packing from seizing to the shaft, it is adjusted to allow a slight leakage of liquid.

Chemical circulator

Chemical circulator

For temperature management of various chemical solutions! A direct circulation type temperature control device essential for wet processes.

At Nippon Excel Co., Ltd., we handle the "Chemical Circulator." This product can precisely control the temperature of chemical solutions used in RCA cleaning and wet etching. Due to its seal structure where the rubber O-ring does not come into direct contact with the liquid, there is no need to select sealing materials for each type of chemical solution, such as acidic or alkaline liquids. Additionally, the heat exchange components of the cooling and heating sections use high-purity glass-like carbon, eliminating concerns about contamination from leached metal ions, and there is no need for a surface protective film, preventing any decrease in performance due to peeling. 【Features】 ■ High-precision temperature control of chemical solutions ■ Suitable for temperature control near room temperature and highly precise due to the electronic cooling and heating method ■ Complies with international protection standard IP31 ■ Built-in leak sensor and temperature switch ■ Meets the demand for increased cleanliness associated with high mega-pit construction *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.
