Centrifugal separator DELTA-ZFA

The centrifugal separator from DELTAFILTER is the right step towards cost-cutting and environmentally friendly filtration. This operating fluid-free separation system requires no maintenance and is therefore particularly cost-effective to use. With its small footprint and the absence of moving parts and backwashing, the centrifugal separator offers a maintenance-free solution that guarantees consistently low differential pressure, high flow rates and excellent efficiency.

The contaminated liquid is fed by the operating pressure via tangential slots into the separation chamber, where the rotation of the liquid creates a central vortex. The resulting centrifugal forces hurl the particles against the outer wall of the separation chamber, from where they sink and sediment into the flow-calmed collection chamber due to gravity and the flow. The sediments can be discharged automatically or manually at intervals.

As there is no need for filter elements or filter bags, there are no operating costs for these components. In addition, the centrifugal separator enables continuous separation without the high liquid losses that can occur with backwash filters.

The centrifugal separator achieves a separation of over 98% of all particles with a specific weight of 2.6 – 2.8 kg/dm³ (sand) and a particle size of around 75 µm or larger. In circulating systems or with two units connected in series, a filter fineness of approx. 50 µm can even be achieved with the same density, whereby heavier particles such as metal chips are separated even more efficiently.
