The Discovery of Gravity Cleaning of industrial fluids with Centrifugal

Technology STA Centrifugal Separators are using the physical effect of phase separation in centrifugal fields for the cleaning of process fluids. Even unfilterable media are reliably cleared from particles or secondary liquid phases without use of disposables. The removed solids are dry and pure. Centrifugal Separators are relatively compact systems and easy to be integrated; they fit a wide range of applications.

Since 1992 STA, as a family-run machine building company with more than 30 employees, has always been truly customer-focused. With application knowledge and thorough system design we are integrating our solutions successfully into our customers’ processes. Relying on modern engineering resources we implement special customer demands quickly and reliably. Based on the experiences from over 1,500 worldwide installed units, and considering always the latest safety regulations we develop high-performance, long-life and safe machines. By means of research on our machines’ fluid dynamics and extensive...

Central Systems

STA Central Filtration Systems are tailored for fluid storing, cleaning and process supply. Besides our STA-made separators we integrate filters and conveyors, tanks, pumps, coolers, heaters and dosing systems.

You only work with the best machines Why not when it comes to process fluid cle Centrifugal Separator – how it works ● The suspension is fed centrally into the rotor ● Liquid is accelerated and moved outwards ● The solids settle on the inner rotor wall ● The clarified liquid overflows and is discharged via a peeler tube ● For sludge emptying the rotor is stopped A good spin on separation performance The fluid-dynamically designed accelerator hub and the big effective flow radius help applying the high rotor accelerations of up to 2.000 g effectively on the liquid and the particles to be separated....

s? eaning? Right and Tight The high acceleration forces also result in an optimum compression of the separated solids. The sludge is dry and can be reasonably disposed or even recycled. A matter of mud If you decide to go for a centrifugal separator as your separating system, most parameters relevant to filtration, such as shape and composition of the solids, become forgettable. Unfilterable additives like greases and polish, or those problematic ingredients in cast alloys namely graphite and silicon just get removed as well. More examples: chlorinated drawing oils, molybdenum, scales, paint...

1One for All - the mobile solution STA Separators are very compact and space saving, on top of this they can be done mobile, to be even more all-purpose and flexible. Due to their own backflow pressure there is no installation works necessary apart from connecting two tubes. 2 Ready for take-off within 3 minutes Manual solid discharge is done with almost a flick of the wrist. After only 3 to 5 minutes the separator is ready again for operation. 3 Struck Oil!

1 The drives: maximum performance and efficiency The innovative drive concept responds to today’s demands for energy efficiency. The inverter controlled 100 Hz drive is more compact than ever, hence very silent and wearless. As an option power modules with low harmonics energy feedback can be used – saving money and improves solids discharge rate by even shorter the breaking times.
