TC-21HD & TC-21J
The Model TC-21J & TC-21HD pump assemblies are single-stage, foot mounted pumps. The TC-21J is jackshaft driven by belt and the TC-21HD is designed to be driven by a hydraulic motor. For the TC-21J, the shaft includes standard size keyways at each end; for the TC-21HD, the shaft is splined for hydraulic motor drive The pump features all bronze construction with pump housings, impeller and inducer all made from bronze with a stainless steel shaft. This construction makes the pump ideal for use in liquid oxygen service in addition to other cryogenic liquids.
