Our customized CGR (Caulked Gasketed Recessed) membrane plate combines the industry-leading 100% leak-free sealing technology of CGR design with high-performance diaphragm squeezing function. Unlike standard membrane plates that suffer from common leakage issues at plate edges, this innovative dual-seal design features caulked filter cloth installation and dedicated O-ring gasket grooves, creating a hermetic seal between plates even under high squeezing pressure. Each plate is fully customized to match your existing filter press model, material properties and process requirements, making it the ultimate solution for demanding applications requiring both absolute leak prevention and superior dewatering performance.
Core Advantages
- Zero Leakage Under High Pressure: Dual sealing system (caulked filter cloth + precision-machined O-ring gaskets) eliminates wicking, dripping and cross-contamination, even at maximum 25 bar squeezing pressure
- Superior Dewatering Performance: Uniform diaphragm inflation delivers consistent pressure across the entire plate surface, reducing filter cake moisture content by 8-12% compared to standard membrane plates
- Maximum Material Recovery: Hermetic sealing prevents loss of valuable mother liquor and solid products, increasing overall process yield
- Enhanced Worker Safety: Completely sealed design eliminates exposure to toxic, corrosive or volatile chemicals, ensuring compliance with strict industrial safety regulations
- Full Customization: Tailored dimensions, diaphragm materials, core plate materials and sealing configurations to perfectly suit your unique filtration needs
- Extended Service Life: High-quality reinforced rubber/TPE diaphragms and heavy-duty core plates resist chemical corrosion and mechanical fatigue, extending service life by 35-45%
