Reverse Balanced Compact Seal

The QMseal Reverse Balanced Mechanical Seal is a specialized sealing solution designed for demanding applications involving high pressures, particularly in processes where traditional internal pressure balancing may be insufficient or detrimental. As leading mechanical seal suppliers and seal manufacturers, we understand the critical role of reliable sealing. Unlike conventional balanced seals, the reverse balanced design applies hydraulic pressure to the outside diameter of the seal faces, effectively counteracting the internal process pressure. This results in a lower net closing force on the seal faces, reducing wear, heat generation and extending mechanical seal life.
