Product Description

Capsulated Spring Balanced Seals offer a budget-friendly substitute to conventional balanced seal designs, while retaining the strength and reliability characteristic of Multi Spring Unbalanced Seals.

Specifically developed for use in processes involving slurry-laden or particle-filled media, these seals feature a protective capsule around the spring mechanism. This enclosure prevents exposure to solidifying fluids, greatly improving operational dependability in harsh environments. Furthermore, their ability to function independently of shaft rotation direction adds to their flexibility, making them suitable for a wide variety of industrial applications.

Applications

  • Commonly applied in corrosive chemical processing

  • Suitable for fluids with suspended solid particles

  • Designed for handling acidic and alkaline substances

Features

  • Pressure-balanced configuration

  • Single-side sealing action

  • Internally installed setup

  • Operates efficiently in both rotational directions
