Products & technology - Multi replaceable empty chamber membrane filter plates

Multi replaceable empty chamber membrane filter plates

The empty chamber Multi version of Klinkau's replaceable membrane filter plate is a development of the clip version and was designed for elastomer membranes. 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.

Using a patented groove around the plate, the membrane is fixed to the body by interlocking at the sealing edges and at the staybosses. No other fixation is required. The design of the groove makes the membrane self-sealing. No other sealing is required. The filtrate, wash water and squeezing medium are reliably kept apart during the entire filtration cycle.

Advantages of the Multi replaceable empty chamber membrane filter plates

  • Permits squeezing into a partially filled or empty chamber
  • No additional sealing required
  • Interlocking clip system to prevent squeeze medium leakages even when opening the filter press
  • CGR version possible (sealed plate design)
  • Bigger pips at the sealing edges to improve filtrate efficiency
  • Special pips at the stayboss chamfer areas to protect the filter cloth
  • Variable choice of materials for high chemical resistance

Technical Data

Sizes310 & 1500 mm. Larger and alternative sizes available on request.
Feed eye positionCentralised feed. Other feed eye positions can be provided according to individual requirements.
PressureStandard products are suitable for maximum filtration pressures of 7 bar and maximum squeeze pressures of 16 bar. Plates also available for higher filtration and squeeze pressures.
TemperaturesThe maximum permissible filtration temperature depends on factors such as filtration pressure, squeeze pressure, the chemical composition of the slurry to be filtered, cycle time and choice of filter material.
MaterialsMembranes are available in the following materials: Polypropylene, modified polypropylene, PVDF as well as our own specially developed membrane material. A combination of different materials can be used for the membrane and membrane body plate.


As with welded membrane filter plates, replaceable membrane filter plates also use membrane squeezing instead of the inefficient phase of pressure filtration, the dewatering to final residual moisture in the filter cake. Filtering efficiency is therefore maximised throughout the filtration phase and filtration times are significantly reduced.

Klinkau's Multi version of its replaceable membrane filter plates is based on the different functions of the membrane and the body 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. This aids even lift of during the squeezing phase and aids an even filter cake build up. The membrane in the Multi design is interlocked to the plate at the sealing edges and at the staybosses and fixed at inlet area with a steel ring. This enables easy and hassle-free membrane replacement.

The filtrate drainage outlets are located only in the plate itself. The membrane is therefore suitable for filtration applications with or without cake washing. The specially designed sealing edges and staybosses prevent compresison set or damage to the membrane when closing the filter press. The pips and drainage channels are designed to optimize drainage area, cake-washing efficiency and help to protect the filter cloth.

Klinkau membrane filter plates have two hinge lines that keep flexion tension to a minimum at the hinge areas during filtration and squeezing thus extending the service life of the membranes. Squeezing into empty chambers is then possible without damaging the membrane.
