SEAL SEAT TYPE 19
CROSS-SECTION OF AN INSTALLED SEAL SEAT TYPE 19

GENERAL DESCRIPTION

This seal seat design consists of a ring with "T" shape section, when installed the seal seat is clamped between the gland and the stuffing box face (sometimes can be clamped between the gland and the gland adapter or between the gland adapter and the stuffing box face), flat gaskets are used to seal the joints between the seal seat and the body of the pump, these gaskets are usually of materials such as asbestos or PTFE, however they can be of metallic materials if pressure and temperature are too high. If it is required the design of the seal seat can be modified by removing one (or even both) of its "shoulders", in this case the seal seat becomes a Type 19 Modified, and thought it may appear to be a "floating style seat" (Type 11) it is still a clamped style.
