Product Summary

Balanced mechanical seals are engineered for most pumps, mixer and agitator applications in maintenance. In many cases the designs have been proven to be workhorses over years of use. In others seals must be designed for evolving industrial demands. Since balanced mechanical seals are subject to stuffing box pressure, this pressure is utilized to achieve and maintain seal face closure in a non-balanced seal.  

When speaking of “Balance” in reference to mechanical seals, we are not talking about mechanical or rotational balance. Instead, we are referring to hydraulic balance. If stuffing box pressure is very high, typically over 100psi., then the closing force may be too great to allow the “Boundary Layer Liquid” that lubricates the faces to be sufficient and the faces will wear prematurely. A balanced seal compensates for higher pressures by locating the seal faces such that stuffing box pressure has less effect on face closure.
