Used Alfa Laval LAPX 404SGP-31G/CG Disc Stack Clarifier Centrifuge – Built 2021

Description

Used Alfa Laval Model LAPX 404SGP-31G/CG disc stack clarifier centrifuge with 316 stainless steel product contact surfaces, built in 2021. Designed for liquid/solids separation, with a maximum bowl speed of 9,600 RPM and listed centrifugal force of 11,000 x G. Rated liquid throughput is 4,000 liters per hour, with a maximum listed solids-handling capacity of 33 liters per hour; actual processing capacity depends on feed characteristics and separation requirements. The rotating disc stack provides separation surfaces for collecting denser suspended solids at the bowl periphery while clarified liquid moves toward the center for discharge under pressure. Features a low-shear disc inlet designed to limit mechanical stress during feed acceleration and a listed process temperature range of 0–100°C. Driven by a 3.7 kW, approximately 5 HP motor rated at 3,600 RPM, 460 volts, 3-phase, 60 Hz. Includes sludge tank, piping and tools. Possible applications include pilot-scale fermentation broth clarification, cell and yeast separation, suspended solids removal from protein-containing liquids, and clarification of compatible beverage and aqueous process streams, subject to material compatibility and separation requirements.

Product Details

Potential Applications

• Pilot-scale liquid/solids separation and process development.
• Clarification of compatible fermentation broths.
• Cell and yeast separation from liquid process streams.
• Removal of suspended particles from protein-containing liquids.
• Clarification of compatible beverage and aqueous process streams.

What Products Would This Be Used For?

Potential feed materials include:

• Fermentation broths containing suspended cells or biological solids.
• Yeast-containing suspensions.
• Cell-containing aqueous process liquids.
• Protein-containing liquids requiring removal of suspended particles.
• Compatible beverage streams containing separable sediment.
• Aqueous process suspensions requiring clarification.

Suitability depends on feed composition, viscosity, particle characteristics, solids loading, temperature and separation targets. Removing suspended solids from protein-containing liquids does not establish separation of dissolved proteins.
