Replaceable membrane filter plate empty chamber overhang

The empty chamber overhang version of the replaceable membrane filter plate has been developed from the welded membrane filter plate and has all its major benefits.

As for all Klinkau replaceable membrane filter plates, this product can also cope with squeezing into empty chambers. Its simple and robust construction makes it the preferred filter plate for all water and waste water applications. Membranes can be replaced easily within minutes even after years of service and even when the membrane body plate shows signs of shrinkage and swelling.

This product was originally intended for water and waste water applications but – due primarily to the ease and economy of replacing its membranes – it is now being widely used within the chemicals industry for processing chemically aggressive slurries. The membrane has reinforced fixing to the plate's lower sealed edge to prevent any unwanted leakage of residual squeezed water.

Advantages of the replaceable membrane filter plate empty chamber overhang

  • Permits squeezing on empty or partially filled chambers
  • Extremely easy membrane replacement even after years of usage
  • Membrane can be replaced within the filter press
  • Variable choice of materials for high chemical resistance

Technical Data

Sizes470mm, 800mm, 1000mm, 1200mm, 1300mm, 1500mm, 1.5m x 2m, 2m x 2m. Larger and alternative sizes available on request.
Feed eye positionCentralised feed, decentralised feed, corner feed, external feed eye 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 materials. A combination of different materials can be used for the membrane and membrane body plate.


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 of its overhanging replaceable membrane filter plate 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 overhang version is loosely fixed to the plate using only a steel O-ring in the inlet area. Changing the membrane is then easy and problem free. The plates do not require removal from the press, a major benefit for top-suspended systems.

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.
