Filter Plate

Rubber Filter Plate

Flexible vulcanized membrane plate for tight sealing, secondary squeezing and lower cake moisture.

Filter Plate Series

Rubber Filter Plate

The rubber filter plate is an elastic membrane plate made through composite vulcanization for secondary air or water squeezing. Rather than acting as a rigid chamber plate, its expandable surface compresses the formed cake to improve dewatering and reduce residual moisture.

Product Description

Composite-vulcanized natural rubber or EPDM forms an expandable membrane surface for the squeeze stage of a membrane press. After the chamber fills, air or water pressure expands the plate and compresses the cake, improving final dryness beyond the initial filtration stage. The listed squeezing range is 0.8–1.5 MPa, with continuous service to 75°C and a pH range of 2–12. Typical duties include municipal sludge, pigments, calcium carbonate, printing and dyeing residue, and selected low-temperature food or pharmaceutical slurries. Specify inflation medium, squeeze pressure, cycle frequency, chemical exposure and required cake moisture when matching the membrane; elasticity and compression recovery are central to service life and sealing performance.
