Single Spring Unbalanced Seals are crafted as single-acting, helical coil spring units that function regardless of shaft rotation direction. Their unbalanced construction and internal mounting design offer flexibility and ease of installation. The rotating seal ring is directly driven by the shaft, delivering smooth, slip-free operation and preventing damage to both the shaft and sleeve.

The spring mechanism is fully isolated from the process media, making these seals an excellent choice for systems that deal with abrasive solids or particulate-laden fluids. Their straightforward configuration enhances both reliability and user-friendliness, making them ideal for demanding applications that require long-lasting, low-maintenance sealing solutions.
