API 685 Pump - End or Top Suction


API 685 Pump - End or Top Suction:

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 pumps offer the utmost in versatility and reliability in the most hazardous 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 of our API-685 pump 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 of any API-685 pump type within 10 minutes
  • Dual back-pull-out design or service either hydraulic end or ball bearing assembly
