Centrifugal Process Pumps WMCA API-685

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 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 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
