The AST60 is the seal we build for the rotodynamic pump fleet — Goulds 3196, Durco Mark 3, Sundyne, anything cut to ANSI B73.1. It's a balanced, dual-flushed cartridge seal in a self-aligning gland. You install it without setting clips, you don't touch the impeller adjustment, and you don't pull the pump. It replaces a Type 21 packed gland in roughly forty minutes.
