FAQ Section - Seal Faces, Seats
Q: What factors should I consider when selecting Seal Faces, Seats for my application?
A: When choosing Seal Faces, Seats, consider the operating temperature, pressure, media being sealed, shaft speed, and chemical compatibility. Silicon carbide offers the best overall performance for most severe services, while carbon graphite works well for non-lubricated applications.
Q: How often should Seal Faces, Seats be replaced in mechanical seals?
A: Replacement intervals for Seal Faces, Seats vary based on operating conditions. Under normal conditions, they typically last 3-5 years. For severe services (high pressure, abrasive media), inspect annually and replace every 1-2 years. Always check manufacturer recommendations and monitor for leakage or excessive wear.
Q: Can damaged Seal Faces, Seats be repaired or must they always be replaced?
A: Minor imperfections in Seal Faces, Seats can sometimes be lapped or refinished by qualified technicians, but significant damage usually requires replacement. Attempting to repair severely damaged faces often leads to premature failure and potential equipment damage.
