GMP Filter Press

All contact parts are manufactured from SS 304, SS 316, or SS 316L stainless steel. The system features specialized 316L construction and a high degree of surface finish to ensure corrosion resistance, sanitary performance, and compliance with FDA and EU guidelines.

Under positive pressure, the liquid slurry is introduced into the filter and flows downward through side openings on the filter plates. Filter media traps solid particles while clear filtrate passes into a central channel formed by interlocking pressure cups connected to the outlet. Filtration continues until the cake capacity is reached or the flow rate drops significantly due to increased cake resistance. The design ensures maximum recovery of filtrate.

Available models feature plate diameters of 4, 8, 14, 18, 24, and 33 inches. Different configurations vary by number of plates, filtering area, cake-holding capacity, motor power, and pump size to match specific production needs.

Key features include maintenance without lifting the full cartridge (only the head needs to be lifted), construction to the latest engineering standards, compatibility with centrifugal/gear/lobe pumps, fitted pressure gauge, safety valve and air vent, crystal-clear filtration from high-finish contact parts, and minimum hold-up of unfiltered slurry for improved productivity.

It is widely used in the pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, cosmetic, and chemical industries—any sector requiring high-purity solid-liquid separation under GMP conditions.

Output ranges from approximately 250 LPH (smaller 8-inch models) up to 21,000 LPH (larger 24-inch models), depending on plate diameter, number of plates, filtering area, and cake-holding space. Motor sizes typically range from 1 HP to 5 HP, with corresponding pump sizes. Power voltage can be adjusted to suit local requirements.

The press uses sanitary 316L stainless-steel construction, high surface finishes on all contact parts, and adherence to FDA and EU guidelines. This combination minimizes contamination risk and supports crystal-clear filtration required in regulated manufacturing environments.

Maintenance can be performed without lifting the entire cartridge—only the head needs to be lifted—reducing downtime and simplifying servicing while maintaining the integrity of the filtration system.

It delivers repeatable, high-purity separation with minimum slurry hold-up, maximum filtrate recovery, robust sanitary design, and full GMP/FDA/EU compliance. These attributes make it ideal for protecting product quality and ensuring batch viability in critical processing applications.
