[Column Introduction] Mechanical Seal

I will provide a detailed explanation about the essential mechanical seal for pumps!

At Yuai Giken, we publish explanatory columns related to bathtubs and pools on our website. In this article, we have written about "mechanical seals." "There's a water leak from the pump, but what could be the cause?" "What is a mechanical seal?" "Is it really a necessary part?" Reading this will resolve those questions. It's easy to understand with illustrations!

Submersible Pump Overhaul Service

Submersible Pump Overhaul Service

Overhaul to maintain the functionality and extend the lifespan of water treatment equipment!

We perform overhauls of submersible pumps. After cleaning, we conduct an inspection of the appearance and measure the insulation resistance. Subsequently, we disassemble the pump and check for corrosion, wear, and deterioration in each part. We pay particular attention to the wear condition of the impeller, shaft (main spindle), wear ring (gap adjustment ring), and ball bearings. 【Overhaul Items】 ■ Cable ■ Motor ■ Ball Bearings ■ Mechanical Seal ■ Impeller, etc. *For more details, please download the PDF or feel free to contact us.

Shaft sealing device [MECO custom shaft seal] *Order production available

Shaft sealing device [MECO custom shaft seal] *Order production available

Solve common issues associated with the use of traditional gland packing, such as powder and gas leaks, foreign matter contamination, decreased vacuum levels, and shaft wear!

We handle the "MECO Custom Shaft Seal" manufactured by Woodex Bearing. This product is an effective solution for shaft sealing in devices such as rotating shaft equipment, where low speeds can cause significant load on the blades, leading to shaft runout that makes conventional mechanical seals unsuitable. Most models are split-type and can be custom-made to fit the user's equipment, allowing for quick changes from packing without the need for on-site modifications or removal of motors. 【Features】 ■ Effective as a shaft seal for devices where conventional mechanical seals cannot be used ■ Custom-made to fit the user's equipment ■ Allows for quick changes from packing on-site ■ Contributes to increased production efficiency and cost reduction *For more details, please refer to the PDF document or feel free to contact us.

POK Backup Ring "Petseals"

POK Backup Ring "Petseals"

POK (polyketone) has superior mechanical and chemical properties compared to fluororesins, nylon, and POM, making it suitable for more demanding applications!

The backup rings for U-packing piston seals and rod seals demonstrate excellent performance in harsh applications with high pressure, high temperature, and frequent pressure spikes. POK (polyketone) is the only engineering plastic primarily composed of carbon that has a high degree of crystallinity and a dense crystalline structure. It is a highly differentiated thermoplastic engineering polymer with excellent chemical resistance, impact resistance, friction properties, and barrier characteristics.

Manufacturing Communication: Mechanical Seal

Manufacturing Communication: Mechanical Seal

High-quality manufacturing is achieved through a combination of NC lathe processing and machining!

We manufacture a component known as a mechanical seal. The mechanical seal emerged around the end of the 19th century. It is a mechanism that seals mechanically to prevent leakage from the rotating shaft that penetrates the pressure vessel (casing) in rotating equipment such as pumps and agitators. Research and development progressed as military technology, but it has rapidly evolved in recent years, spurred by the advancement of various industries, including the chemical industry. It is unfortunate that images cannot be included, but due to its mechanical properties, the nature of the mechanical seal prevents oil and water leaks, which means that the geometric tolerances for aspects such as flatness, parallelism, and perpendicularity of the components are extremely strict. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.

Mechanical seal

Mechanical seal

Anything related to shaft seals, seals, gaskets, and pumps! Please consult us for urgent or immediate cases.

We offer a wide variety of "mechanical seals." Our products are highly regarded for their pressure resistance, heat resistance, wear resistance, viscosity, corrosion resistance, and rotational performance, and are used in various fields, including chemical plants, pulp plants, and food-related plants. Additionally, we have "dry seals" that do not use sealing liquids, preventing the reduction of product purity due to leakage, as well as "cartridge-type mechanical seals" that can be used with liquids containing slurries. 【Product Lineup】 ■ Mechanical Seals ■ Dry Seals ■ Cartridge-Type Mechanical Seals *For more details, please download the PDF or feel free to contact us.
