Stainless steel plate frame multi-layer filter is a precision liquid filter machine, with a mirror polished overall surface, using filter cloth and membrane filtration, adding sealing strips, and stainless steel pump.

The suspension is pumped into each sealed filter chamber of the filter machine. Under pressure, the filtrate passes through the filter layer, membrane or other filter materials, and is discharged through the outlet. The filter residue remains in the plate frame to form a filter cake, thereby achieving solid-liquid separation.
