Single Spring Unbalanced Mechanical Seals are internally mounted seals designed for a variety of industrial applications, including water treatment, oil handling, sugar processing, and the chemical industry. These seals provide a cost-effective, durable, and reliable sealing solution where leak prevention and ease of installation are essential.

Driven by a drive ring or drive collar, the rotary unit transmits shaft motion to the spring, enabling stable sealing in moderate pressure conditions. Their non-clogging spring design makes them suitable for corrosive, abrasive, and viscous media, while special torque notches ensure strong drive and allow function regardless of shaft rotation direction.

Built for high-temperature pumps and demanding operations, Single Spring Unbalanced Mechanical Seals offer rugged construction, quick maintenance, and long service life. Their proven reliability and economical design make them ideal for standard-duty industrial sealing applications.
