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)."

"What is secondary sealing material? What types of materials are there?" Let's explain that question and introduce the required characteristics.
This document provides information about the 3rd Basic Course on Mechanical Seals, addressing questions such as "What are secondary sealing materials? What types are available?" The sealing part of a mechanical seal consists of a sliding surface for the primary seal and packing/gasket for the secondary seal. Each secondary seal includes a rotating ring (packing) and a stationary ring (gasket). *Moving part = packing / stationary part = gasket. Depending on the environment in which they are used, various cross-sectional shapes and materials will be selected.

"What are single and double types? What do they mean?" Let's explain that question! Introducing differential pressure management and more.
This document provides information about the 8th Mechanical Seal Beginner Course and will explain questions such as, "What are single and double types?" When using one mechanical seal, it is referred to as "single type." When using two mechanical seals, it is referred to as "double type." Generally, single type is used, but for fluids that are difficult to seal with a single type, a double type is employed. For example, slurry liquids and wastewater have good sealing properties with double type seals.
