[Case Study] Special Structure Mechanical Seal

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

At a quarry factory with water washing equipment, the use of asbestos in the gland packing of slurry pumps was prohibited, and when it was changed to non-asbestos material, leaks occurred within about a week, whereas previously there had been no issues for three months. This led to difficulties due to the frequent leaks and maintenance of the pumps.

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

Reduction of maintenance frequency, increased longevity, and improved sealing performance with a special mechanical seal.

At a stone quarry factory with washing equipment, the use of asbestos in 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, which has caused problems due to the frequency of pump leaks and maintenance. 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 and taking half a day for replacement. 3. Slurry leaks onto the surrounding floor, necessitating daily cleaning. We have received a request to reduce these tasks as much as possible.

Shinmeiwa Industries Co., Ltd. Overhaul Case Studies

We recommend overhauling to maintain performance for a long time through inspection and maintenance.

At Shinmeiwa Industries and Shinmeiwa Aqua Tech Service, we are committed to our after-service business with the philosophy of "restoring equipment during overhaul to a condition as close as possible to its initial delivery state." In our own factories and technical centers, as well as at service-certified stores that meet our technical standards, we provide peace of mind and safety through services that ensure customer "expectations, trust, and satisfaction" not only in terms of equipment but also through advanced technology. In our overhaul case studies, we introduce examples of overhauls for key components such as the "shaft (main axis)," the "impeller," and the "mechanical seal" that protects the pump. 【Inspection Items】 - Cables and Motors - Ball Bearings - Mechanical Seals - Impellers - Pump Casings ● For more details, please contact us or download the catalog.

Mechanical Seal Product Catalog

Leveraging years of experience gained in pump manufacturing, we offer 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 fluids at the sliding surfaces that rotate relatively between the seat (fixed ring) and the washer (rotating ring). We offer a wide range of products, including the "LU1000 series" of 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 and agricultural pumping, drainage, and irrigation plants ■ For chemical and petrochemical plants *For more details, please refer to the PDF materials or feel free to contact us.
