The AC/TC-21 pump assemblies are belt box driven cryogenic centrifugal pumps that are available as either a single- or a two-stage pump. The pump features all bronze construction making the pump ideal for use in liquid oxygen service in addition to other cryogenic liquids. Different styles of shaft seals are available for the pump assembly. These include mechanical or gas riding types, some of which can be purged using the optional purge system. The electric motors supplied as standard are NEMA frame sized, three phase, TEFC, C face type. Motors can also be supplied that meet IP 54, 55, or 56.
