The filter plate is the heart of any filter press. Plate material selection directly determines chemical compatibility, temperature range, and filtration performance.
Polypropylene (PP) Plates
Polypropylene plates dominate industrial filtration with pH 1-14 resistance and 80°C capability. The PP Membrane Filter Press uses membrane plates with flexible PP diaphragm that squeezes cake, achieving 30-50% lower moisture than conventional chamber plates.
Cast Iron Plates
Cast iron plates provide durability for high-temperature (150°C), high-pressure (16 bar) applications. The High Pressure Filter Press employs cast iron plates for mining and chemical processing.
Plate Design and Automation
Plate design includes gasketed and non-gasketed configurations. The Automatic Filter Press System integrates automated plate shifting. Filter cloth must match plate type. The Oil Filter Press uses specialized plates for oil purification.
