[Case Study] Special Structure Mechanical Seal

Improved sealing performance with a special mechanical seal, reducing maintenance!

At a stone quarry factory with water washing equipment, the use of asbestos in the gland packing of slurry pumps has been prohibited, and after switching to non-asbestos materials, leaks that previously did not occur for three months began to happen within about a week, necessitating replacements. They were troubled by the frequent leaks and maintenance of the pumps.

[Case Study] Reduction of Maintenance Frequency with Special Mechanical Seals

Reduction of maintenance frequency, extension of lifespan, and improvement of sealing performance with a special mechanical seal.

At a stone quarry factory equipped with washing facilities, the use of asbestos for the gland packing of slurry pumps has been prohibited, and it has been changed to non-asbestos materials (Note 1). Previously, there were no issues for about three months, but now leaks occur in about a week, necessitating replacement, causing difficulties due to the frequent leaks and maintenance of the pumps. 1. The packing replacement work takes about an hour for a weekly replacement. 2. Slurry leaks also adhere to the bearings near the packing, requiring the pump to be disassembled every six months, taking half a day for replacement. 3. Slurry leaks onto the surrounding floor, necessitating daily cleaning. We received a request to reduce these tasks as much as possible.

Mechanical Seal Product Catalog

Leveraging years of experience gained in pump manufacturing, we provide products tailored to various cases!

"Mechanical seals" play an important role in supporting safety and economy as shaft seals for rotating machinery such as pumps, water wheels, agitators, and centrifuges. They prevent the leakage of sealing fluid at the sliding surfaces where the seat (stationary ring) and the washer (rotating ring) rotate relative to each other. We offer a wide range of products, including the "LU1000 series" rubber bellows seals, as well as rotating single-spring seals such as the "HU2000 series (unbalanced type)" and "HB2000 series (balanced type)." [Contents] ■ Trisima and mechanical seals ■ For power generation plants ■ For seawater desalination plants ■ For water supply and sewage treatment plants ■ For river, agricultural drainage, and irrigation plants ■ For chemical and petrochemical plants *For more details, please refer to the PDF materials or feel free to contact us.

[Case Study] Two-Part Mechanical Seal That Can Be Installed Without Disassembling the Pump

Can be installed without disassembling the pump - 2-part mechanical seal.

In a factory using dozens of large circulation pumps for cooling water, frequent water leaks from the pumps were causing problems. These pumps used gland packing as the sealing material, but the packing was not sealing properly, resulting in water leaks that left the surrounding area soaked. The factory's production was busy, making it difficult to stop the pumps frequently, and due to the large number of pumps, adjustments to tighten the packing or address water leaks while the pumps were operating were not performed for safety reasons. 1. Increased loss of water and costs for recovery and cleaning. 2. Reduced lifespan and damage to bearings, and pump failures due to water leaks. 3. Wear on the pump shaft caused by gland packing. 4. Adjustments to rotating equipment while in operation are not possible due to the risk of entanglement. 5. Maintenance requires extensive work using tow trucks or similar equipment due to the size of the pumps. We received an inquiry about wanting to reduce these tasks as much as possible.
