It sits on the pump shaft and prevents fluid from leaking out of the pump casing, using a carbon rotating face and a Buna-N (nitrile) O-ring. You replace this seal when you see a steady drip from the shaft area or during a pump rebuild, to avoid product loss and keep the pump running efficiently and safely.
