Replaceable membrane filter plates empty chamber clip

The empty chamber clip version of Klinkau's replaceable membrane filter plates is a development of the overhang version. It has all the major benefits of the welded version. As for all Klinkau replaceable membrane filter plates, this product can also cope with squeezing into empty chambers.

The membrane plate is equipped with a special clip system at the sealed edges so that no other extra fixing is necessary. Perfect sealing between the membrane and plate is achieved through the membrane itself. Seals are therefore automatically replaced when the membrane is replaced.

Advantages of Replaceable membrane filter plates empty chamber clip

  • Permits squeezing on empty or partially filled chambers
  • No additional sealing required
  • Interlocking clip system to prevent squeeze medium leakages even when opening the filter press
  • Ring channel covering the whole filtration surface for optimized wash water circulation
  • Variable choice of materials for high chemical resistance

Technology

As in welded membrane filter plates, replaceable membrane filter plates also use membrane squeezing during the unproductive phase of pressure filtration. Filtering efficiency is therefore maintained throughout the filtration phase and filtration times are significantly reduced.

Klinkau's clip version is based on the different functioning of the membrane and the membrane plate. The plate's function is to cope with the mechanical requirements of a chamber filter plate. It is designed to support the membrane during the filtration process. The plate has a pipped profile so the membrane does not lie completely flat to the plate.

The membrane in the clip version is connected to the plate at the sealed edge with an interlocking mechanism, and at the centralised feed area with a steel O-ring.

The filtrate drainage outlets are located only in the plate itself. The membrane is therefore suitable for filtration applications with or without cake washing. A ring channel covering the entire filtration surface optimizes wash water circulation behind the filter cloth, making this membrane filter plate ideal for applications requiring highly efficient cake washing. Klinkau membrane filter plates have two hinged lines that keep flex pressure to a minimum at the hinged areas during filtration and squeezing, thereby extending the service life of the membranes. Squeezing into empty chambers is then possible without damaging the membrane.
