    Hi everyone,
    Anyone have seen and studied yet, leakings in mechanical seals of positive displacement pumps and may you share how to solve this problem?
    We are studying this problem for one product we have in the process of pesticides´manufacturing (formulation). We did inversions in the addition sequence in this formulation with no results for this leaking . We are studying about the vapor pressure of the mixture and the seal´s vendor suggest to create a ventilation/ snorkel for the sealing box in one pump. The seals were verified and there aren´t no signs of corrosions or damage in this.
    I hope you all can contribute with me in this problem.
