Centrifugal,Process,Pumps,WMCA-ANSI B73.1 Series,WarrenderCentrifugal Process Pumps:

The WARRENDER WMCA-ANSI B73.1 alloy centrifugal process pumps (superseding the MCA) feature a hydro dynamically balanced impeller and proper running clearances. The WMCA designs are the benchmark for heavy-duty seal-less process pumps are suitable for standard applications, and extreme high temperature or cryogenic services. WMCA alloy centrifugal mag-drive designs are available in NEMA close-coupled and long-coupled pedestal configurations.
