Backwash Filter

Backwash Filter

The classic backwash filter with connection sizes from DN15 to DN 300 can be used for manifold different applications, i.e. from low viscosity to high viscosity fluids, for oils and for greases.

Compact forms of execution make the ideal starting point for integration into the overall concept whereby different forms of execution and material variants enable a wide range of applications to be covered. Filtration qualities from 10 µm are possible. Different backwash techniques can be selected in order to maximize the service life of the filter coils.

To meet specific customer requirements it is often sufficient to make small adaptations to as-given standard solutions.

Lamella Separators

Lamella Separators

Our lamella separators are the heart of our preparation systems. They work with the very highest reliability and robustness around the clock in order to provide your machine tools with process fluid.

The principle has a long tradition and has been optimized with the most modern simulation techniques in such a way that the very highest degrees of separation coupled with very low space requirements are possible.

The system brings together the following attributes:

  • Very low maintenance
  • High availability
  • No filtration auxiliaries
  • Low energy requirement
  • Clean form of execution
  • Long service life
  • Very low manpower requirement
  • Easy to maintain
  • Very high degrees of separation
  • Low quantities of residual sludge

Thereby lamella separators are particularly well suited for forming the heart of systems providing high availability.

THE CORE PRINCIPLE

The central component of the filter system is the lamella pack. The contaminated medium is fed to the lamella pack from beneath. As the medium flows through the lamella pack the solid and lightweight substances are continuously separated from the medium.

A laminar flow profile is generated in each individual lamella. Through the sedimentation effect heavy materials that are present are guided downwards to the lamella surface through the natural gravitation field. On this surface of the lamella a return flow is created; this carries the heavy materials downwards from the lamella pack. While the heavy materials are transported downwards, the lightweight materials are guided upwards to the under edge of the lamellas through the difference in specific gravity. Thanks to the coalescence effect at the lamella surface, fine lightweight material drops are also separated off. The flow of lightweight materials is separated off upwards from the lamellas.

A high degree of separation is achieved through this combined effect of flotation and coalescence.
