Product Description

Filter Press is by far the most effective sludge dewatering equipment. Our Filter Press machines are designed with maximum filtration pressure of 20 bar, can help you achieve the lowest possible cake moisture. Due to decades of working experience with numerous materials/conditions, we can easily provide you the best advices and most suitable models to your process design. Contact us now for a professional proposal!



Filter press is an effective type of dewatering equipment working in batches, applicable to various solid-liquid separation. Filter press is effective, easy to use, suitable for large filtration plants that requires a high degree of automation or centralized control, with filter pressure of 0.8 Mpa min.. The whole machine is designed with integration of machine, electricity and liquid, can realize automatic pressing, filtering, draining, squeezing, loosening, drawing board, and so on, with a high degree of automation, large production capacity, low liquid content in filter cake,  high unit output, requiring only very limited area for installation&operation. Widely used in petroleum, chemical industry, dye, metallurgy, pharmacy, food, paper making, coal washing,water treatment and sewage treatment and so on all kinds of solid-liquid separation is required.

Automatic filter press is on the basis of the pressure filter, according to user's different requirements for filter press equipment automation degree, choose to increase automatic plate system, auxiliary varicose arm of discharging slag system, single lever water flushing system, flap hydraulic system, PLC control system and other auxiliary facilities, in order to reduce the workers labor intensity, improve production efficiency.

Our Filter Press for mining tail pulp treatment was designed with high pressure, robust structure for harsh working conditions and long-term reliability.



Main Structure


Frame:                The steel frame acts as a clamping device for the filter plates.

Filter Plates:      A filter cake forms in the chambers between filter plates.

Filter Cloth:       A cloth filter that is attached to both sides of a filter plate. Solids build up on cloth to form a filter cake, separating liquids from solids.


Available options according to:

Closing mode:              manual, gear drive, hydraulic;

filter plate structure:    recessed plate, diaphragm squeeze (membrane) plate; plate &frame

filter plate material:      PP, rubber, cast iron, stainless steel;

Filter Plate size(mm):  320, 450, 630, 800,1000, 1250, 1500,2000

Working principle of Membrane Filter Press:

  1. Feeding:  Slurry is pumped into the filter press. The solids are distributed evenly on the filter cloths during the feed (fill) cycle.
  2. Filtration: Solids begin to build on the filter cloth, trapping the ensuing particles and building a filter cake. The filter cake acts as a depth filter for solid/liquid separation. Filtrate exits the plates through the corner ports into the manifold.
  3. Filtration completed: When the correct valves in the manifold are open, the filtrate exits the press through the filtrate outlet. As the filter press feed pump builds pressure, the solids build within the chambers until they are completely full of filter cake.
  4. Membrane Squeezing: Once the chambers are full, the fill cycle is over, high pressure water or compressed air will start fill in between membranes of filter plates, pushing the membrane toward the filter cakes, squeezing the filter cakes to remove any residue water.
  5. Presssure relief:  when squeezing is over, high pressure water(compressed air) is released from between the membranes.
  6. Cake discharge: after pressure relived, the filter press is ready to discharge cakes.

(* Note: 4, 5 is only for membrane filter press)

Membrane Filter Press Models & Technical Data


How to order your filter press:

  1. Firstly, please refer to technical data of filter press, choose a suitable model, plate material, plate closing mode, filtration flow mode.
  2. Based on production requirements, please choose between: open-flow, close-flow; cake washing, non-washing before ordering.
  3. Slurry feeding pump, squeezing pump(or air compressor) is not included in the filter press machine by default, please add them to your purchase order if they are requested from us.
  4. Customized filter press for special working conditions are available, please feel free to present your requirements.
  5. Due to upgrade of machines, all technical data are subject to change without prior nofications.
