Centrifugal,Process,Pumps,WMCA,API-685,WarrenderCentrifugal Process Pumps:

The WARRENDER WMCA API-685 alloy centrifugal process pumps (superseding the MCA) are built for critical services and extreme system pressures in full accordance with the API-685 specifications. The WMCA designs are the benchmark for heavy-duty seal-less process pumps. The WMCA API-685 process pump offers the utmost in versatility and reliability in the most Horizontal,End Suction,Centrifugal,Process,Pump,ISO-2858 Series,Warrenderhazardous and severe applications. WMCA alloy centrifugal mag-drive designs are available in API 610, API 685 and API 685 multistage configurations. Dynamically balanced, back-to-back impellers allow for minimal axial load on multistage units.

Features:

  • Casing built with heavy wall thicknesses

  • The standard one-piece Hastelloy C276 containment housing exceeds ASME pressure vessel codes; rated for 350 PSI working pressures with capabilities to 1500 PSI

  • External lubrication maintains highest pressure differential, enabling dead-head operation

  • Backed by silicon carbide thrust bearings, impeller pump-out vanes balance axial thrust

  • Quick-change rear cartridge assembly (an WMCA standard) allows for replacement and restart-up within 10 minutes

  • Dual back-pull-out design or service either hydraulic end or ball bearing assembly
