We have not heard from you. What is the name of your plant and your location? Can you send me pictures of the v-seal? Our old design used a v-seal and has since been replaced with the Quantum that uses no seals to ever wear out. Can you send us your PM history? What is the frequency of your oil changes? Answering these questions would be a start.
Please contact me ASAP and we can help you resolve your problem.
