FPS filter

Operating principle

The plate pack is located between two rigid plates and is opened plate by plate with the plate-shifting device and closed by a hydraulic cylinder.

In the closed position the plates form a solid pack of sealed chambers with two filter cloths between each pair of plates. The process liquid enters through slurry distribution channels that are formed when the plate pack is closed. The slurry is pumped into all chambers simultaneously to form a filter cake on both sides of the chamber. After filtration is complete, the plate pack opens and the cake is discharged.

Thanks to the modular design of the FPS filter press, it can be configured with optional accessories to meet the requirements in standard filtration applications.

Safety devices

The FPS filter press is available with different safety device options, including light curtains, a pull-wire switch as protection against mechanical movements, and movable or fixed splash guards to protect against hot and toxic slurry.

Electrical control system

The filter press features Siemens S7 series control and an HMI system system for easy, stable operation. The system can be configured according to the operating condition and process requirements.

Side bar design

The side bar consist of 800/1000/1250/1500/2000 mm series bars for both chamber filter and membrane filter. The overhead beam is recommended for applications in harsh conditions.

Plate shifter for side bar

A plastic anti-corrosion chain cover protects the chain against slurry residue and corrosive mater, as well as reduces noise. The variable-speed drive enables the shifter speed and torque to be adjusted.

Plate shifter for overhead beam

The top single-point shifting device helps prevent non-synchronous movement of the side-bar shifter. Using the torque in the overhead beam to control plate shifting helps to prevent corrosion caused by contact with slurry residue. The shifting movement is precise, smooth, and easy to adjust, with reduced wear resulting in longer component lifetime.

Hydraulic power unit (HPU)

The hydraulic power unit (HPU) is the main power system of the filter press, and can be either standardized or configured according to requirements. 

Cloth washing device

The cloth washing device uses an advanced retractable cleaning arm and water at a maximum pressure of 60 bar for higher cleaning efficiency and lower water consumption.

Head piping with valves and instruments

Metso Outotec provides a complete set of piping, valves, and instruments to meet the needs of the filtration process. Commissioning of head piping is completed at the factory to enable quicker on-site commissioning and easy operation after the piping and wiring connections have been completed.
