Hermle SIEVA-3Filtration Centrifuge

The Hermle Sieva-3 Filtration centrifuge offers a wide range of applications in chemical, pharmaceutical, biotech, food processing and research laboratories. The two options of either perforated or non-perforated rotor baskets make the Sieva-3 ideal for filtration or solid/liquid sedimentation (decantation). The rotors are designed with cone-shaped centers to guarantee an even spread of filtered material and rinsing agent. The powerful induction drive motor reaches speeds of 10,000 rpm or 7,825 x g.

By an opening in the lid it is possible to fill the centrifugal basket during rotation. The solids remain in the centrifugal basket and the liquid can run off through a opening on the right side. The inspection window in the centrifuge lid is made of safety glass and enables a visual monitoring of the centrifugation.

The SIEVA-3 is very versatile and suitable for various applications. The cmplete housing is made of stainless steel and is therefore also resistant to highly corrosive agents.

The operating principle of this centrifuge is the cake filtration, the filtration in which the required pressure force is generated in the centrifugal field.

The perforated rotor is lined with a filter cloth. Due to the continuous inflow of the suspension, a filter cake builds up in the rotor, while the clarified liquid drains through the rotor casing or on the edge of the basket.

The filtration centrifuge Sieva-3 is mainly used for batch separation of relatively coarse particles or crystalline substances.
