This is a standard mechanical seal assembly for Blackmer TXSD3E and other compatible 3-inch sliding vane pumps. It forms a rotating seal around the pump shaft to prevent fluid leakage and protect the bearings from contamination. Replacing the seal is part of routine pump maintenance or rebuilds, especially when leaks develop or performance drops due to seal wear.
This seal is the standard TXSD version with FKM (Viton) O-rings. It can be used in place of Buna-N seals (331880) on other 3' Blackmer pumps when superior chemical resistance or higher temperature capability is required.
