Used Westfalia NA-7-06-076 Nozzle Disc Stack Clarifier Centrifuge – 8,510 RPM

Description

Used Westfalia Model NA-7-06-076 desludger/nozzle disc stack clarifier centrifuge with stainless steel product contact surfaces, cart mounting and Allen-Bradley controls. Configured for liquid/solids separation, the rotating disc stack provides separation surfaces for directing denser suspended particles toward the bowl periphery while clarified liquid moves inward for discharge under pressure through a centripetal pump. Maximum bowl speed is 8,510 RPM. The NA 7 design combines nozzle discharge of concentrated solids with a hydraulically operated self-cleaning bowl for removal of accumulated sediment. Equipped with a flange-mounted 7.5 HP drive motor rated for 230/460 volts, 3-phase, 60 Hz electrical service. Includes a control panel with an Allen-Bradley MicroView operator interface and MicroLogix 1000 programmable logic controller. Serial number 1662-274. Possible applications include yeast recovery, fermentation broth clarification, biomass concentration and suspended solids removal from compatible aqueous process streams, subject to feed characteristics, installed nozzles and separation requirements.

Product Details

Potential Applications

• Recovery and concentration of yeast from compatible liquid streams.
• Clarification of fermentation broths containing separable suspended solids.
• Biomass concentration where particle characteristics support centrifugal separation.
• Removal of suspended solids from compatible aqueous process liquids.

Throughput, solids concentration and clarification results depend on feed properties, nozzle configuration and operating conditions.

What Products Would This Be Used For?

Potential feed materials include:

• Yeast-containing fermentation liquids.
• Aqueous cell and biomass suspensions.
• Fermentation broths containing suspended biological solids.
• Compatible aqueous process streams containing separable particles.

These describe potential processing duties, rather than documented previous use. Product compatibility and the installed separation configuration determine suitability.
