Solids retaining separator for liquid/liquid/solid separation
Achieve precise liquid-liquid-solid separation even with low solids content, optimizing purity and efficiency across diverse applications.

Separates and Purifies Liquid-Solid Mixtures
The Seital Solids Retaining Separator from SPX FLOW is engineered for precise separation in industries ranging from beverage and dairy to oil and gas. Utilizing a high-speed centrifugal field, it efficiently separates liquid-liquid-solid mixtures, ideal for producing milk fat concentrates, essential oils, and more. Operating with low solids content (less than 0.2% by volume), its centrifugal force recovers fine particles between 0.5 to 500 microns, ensuring high product purity.
The unit possesses a unique bowl design with a high number of disks, dividing its internal space into thin layers for enhanced separation efficiency. Solids collect at the bowl periphery, to be removed manually, while optional collection baskets facilitate faster solids handling. The separator’s centripetal pumps maintain steady output flow without rotational movement, converting kinetic to static pressure for efficient product discharge.
Automated features include micrometric adjusting valves and sight glasses for precise operation control. Designed for integration into complex production lines, it lends itself to CIP systems, minimizing downtime. Available in corrosion-resistant materials, it meets strict industry standards and supports tailor-made configurations for specific processing needs.
