Product Description

Designed for use with slurry-laden fluids, mildly contaminated substances, and media prone to clogging, Single Spring Balanced Seals are purpose-built to address these operational demands. Their specialized structure allows for direct installation on standard shafts without requiring extra balancing modifications. A grub screw firmly attaches the mechanical drive to the shaft, allowing for secure disengagement when needed.

These seals feature a compact design with minimal axial length, making installation quick and convenient. Switching between balanced and unbalanced versions is simple—just replace the carbon face assembly with the included circlip to achieve the desired setup.
