KFP-A Chamber Filter Press - Fully automatic filter power based on side beams
The filter presses are characterized by high flexibility and adaptability. Each system is precisely tailored to the customer's requirements and the respective operating conditions. Variable filter sizes enable individual solutions for a wide range of industries – from the chemical and food industries to wastewater treatment.
Thanks to their modular design, the systems can be easily expanded and adapted. Configurations in terms of degree of automation, material design, plate type and control and safety systems can be flexibly implemented. A robust main cylinder ensures powerful closing of the plate pack. Sequential plate opening – one plate per second – enables an efficient emptying process, especially at high throughput rates.
Standard sizes, from 200 x 200 mm to 1500 x 1500 mm are available. Simatec thus covers applications from laboratory scale to large-scale industrial production.
With practice-oriented engineering, high quality standards and consistent customer focus, Simatec sets benchmarks in filtration technology. The systems impress with their operational reliability, easy maintenance and long service life – decisive advantages for continuous use.
Simatec Chamber Filter Press KFP-AK
Filter performance with system – side carrier meets cake discharge reliability
With the KAS system, Simatec has developed advanced technology for optimizing cake discharge in chamber filter presses. It is specifically designed for applications where conventional discharge methods reach their limits – for example, with highly adhesive or moist filter cakes and difficult discharge conditions.
The system has a modular design and can be used on all side carrier models – regardless of press size or plate type. It is suitable for both new systems and for retrofitting existing presses.
At its core is a series of precisely controlled pneumatic cylinders above the plate pack. These are connected to mechanical elements that actively support each filter plate and the associated filter cloth during the opening process. This reduces the adhesion between the cloth and the plate surface and facilitates the removal of the cake – even with low dead weight or high moisture content.
Depending on the process requirements, two operating modes are available:
- KAS in active mode: This mode is used when the cake adheres strongly and does not fall out on its own. The pneumatic holding cylinders actively push the cloths downwards and break the adhesion between the filter cake, cloth and plate. This allows the chamber to be completely emptied.
- KAS in passive mode: Suitable for brittle or deformable cakes that could become jammed during unloading. Here, the holding cylinders merely serve as a holding device for the filter cloths, which move with the sliding filter cake. This prevents jamming and supports gentle discharge.
The combination of mechanical support, intelligent control and adaptable operation makes the KAS system a reliable solution for automated cake discharge – even under difficult conditions. It minimizes downtime, increases operational reliability and sustainably improves the efficiency of the entire plant.
Chamber filter press KFP-SA
The smart semi-automatic solution with side beams
The single-plate principle enables fast, targeted and safe access to each individual filter plate. Two automated carriages guided on a side carrier precisely move the plates – one after the other – during the opening process. This reduces mechanical stress, prevents plate damage and facilitates visual inspection and cleaning of each chamber. The operator can intervene in a targeted manner without having to open or move the entire plate stack, which is particularly advantageous for highly adhesive or sensitive filtrates.
The semi-automatic control system ensures high user-friendliness while reducing automation costs. It offers a balanced relationship between efficiency and investment costs. The control system can be flexibly adjusted to different operating modes, depending on the process requirements and the desired degree of automation.
This filter press technology is mainly used in the treatment of process sludges, in particular chemically or chemically-physically treated sludges, such as those produced in the chemical industry, metal processing or industrial wastewater treatment. In these applications, precise separation and safe discharge of the filter cake are essential.
Chamber filter press KFP-U
The high-performance filter press for demanding environmental applications
The chamber filter press KFP-U is the most powerful model in the Simatec portfolio. It was developed for industrial applications with high throughput, automated processes and intensive use – especially in wastewater treatment, water treatment, chemicals and mining.
Upper beam design with free maintenance access
The load is transferred via a robust upper beam structure. This leaves access to the plate pack free from all sides, which greatly facilitates maintenance, inspection, cloth replacement and cleaning and reduces mechanical damage.
Multifunctional automation trolley
A centrally controlled trolley combines several core functions:
- Plate opening: Automated single or composite opening with precise time management.
- Vibration system: Impulse-assisted cake release for materials that are difficult to empty
- Cloth washing system: Integrated high-pressure cleaning for constant cloth permeability and cycle optimization.
- Plate crane: Internal lifting system for quick replacement of individual plates – without external aids.
Hydraulic system with four corner cylinders
Symmetrical force transmission via four hydraulic cylinders at the plate corners ensures even loading of the press frame. This increases frame stability, minimizes deformation and improves operational safety – even during pressure or temperature peaks.
Double-beam core for high frame rigidity
The support structure is designed to withstand high mechanical loads and supports plates, carriages, and auxiliary systems without deformation. This reduces vibrations and ensures precise motion sequences even during continuous operation.
Side-opening plate package
Instead of linear movement, the plates are opened by swiveling or extending sideways. This saves space, improves access and speeds up maintenance work.
Options Chamber Filter Presses
Filter Cake Washing
Filter cakes of sludges, which are difficult to press can be exposed to air after the pressing process. It streams from one side to the other. Liquid which has accumulated in the pores is extracted.
Washing Robot
The cloths oft he filter press are automatically cleaned off by a high-pressure water yet. The spaying beam fitted to the moving washing robot is moved up and down between the filter plates to clean the cloths. This ensures that the cleaning is done carefully and reliably by the spray nozzles.
Drain Tray
A drip tray fitted under the filter press collects the filtrate and washing water and returns it back to the closed water circuit. While the cakes are being emptied, the drip tray is automatically opened and then closed again.
Core Blow Unit
Prior to opening the filter plates at the end of the filtration cycle, compressed air blows the remaining liquid sludge out of the centrals filling channel and back into the sludge pipe, thus preventing the dry, semisolid filter cake from being contaminated with remains of liquid sludge.
Filter Cake Washing
In applications where the filter cakes might be contaminated or substances, which can be reclaimed might be lost, there is the possibility of rinsing out the filter cakes during the pressing process with liquid media.
Membrane compression
An additional compression and the resulting additional drying of the filter cake is carried out by a membrane embedded in the filter plate. Membranes up to a size of 1000 mm are filled with air while membranes over 1200 mm in size are filled with water.
