The diaphragm boasts excellent chemical resistance and fatigue resistance, with a special structure and material that enhances its elasticity. A large squeezing stroke allows for thin, low-moisture filter cakes. At room temperature, the squeezing pressure can reach up to 1.6 MPa. Compression air or high-pressure water can be used as the squeezing medium. The diaphragm has a long service life. The modular design facilitates easy diaphragm replacement, reducing equipment operation and maintenance costs.
