Sulzer Pump Mechanical Seal

Keeping Sulzer Pumps Running Between Shutdowns

A Sulzer pump is usually a critical part of the process, so an unplanned seal failure costs far more than the seal itself. Most early failures come from dry running, poor flushing, or a seal that does not match the original dimensions. Our Sulzer pump seal is made to the original fitting dimensions, so it goes into the existing stuffing box without any modification to the pump. Fitting is simple. Clean the shaft and sleeve, seat the stationary ring squarely in the gland, set the rotary unit to the correct working length, and tighten the gland evenly. The carbon rotary face is paired with a hard Silicon Carbide stationary seat. This pairing handles abrasive and mildly corrosive fluids, runs cooler on start-up, and keeps leakage low through long duty cycles. The result is longer seal life and fewer maintenance stoppages. Share your pump model and shaft size with us and we will confirm the correct seal before you order.
