Programmable Automatic High-Pressure Diaphragm Filter Press

The Programmable Automatic High-Pressure Polypropylene Diaphragm Filter Press utilizes high-pressure polypropylene as the diaphragm material. Unlike traditional chamber filter presses, this machine features two elastic membranes installed on both sides of the diaphragm plate. During operation, a high-pressure fluid is injected into the diaphragm plate. When the filter cake completely fills the filtration chamber, the filtration process stops. Next, an expanding medium, such as water or air, is injected into the diaphragm plate, causing it to inflate. This inflating diaphragm applies pressure to the filter cake, and as the pressure builds up, the liquid that can pass through the filter cloth is pushed out. This process allows for secondary dewatering, significantly lowering the moisture content of the filter cake.
