P01+62A BSTXX, P11+62 USTXX. There is no explanation for these in API682 either; what do the suffix letters mean?

P01: Internal circulation from the high-pressure area inside the pump to the sealing chamber； 62: Emergency cooling fluid or steam supplied to the outside of the sealing gland ； I don’t know what the A after 62 means ； BSTXX: B--balanced type, S--single-end face, T--with throttle bushing, XX--material of the stationary and rotating rings as specified ； USTXX: U--Unbalanced type.
