Based on the original program-controlled automatic high-pressure polypropylene diaphragm filter press, this product has been enhanced with a water washing and vibration discharge device. The water washing function improves work efficiency and extends the service life of the filter cloth. Driven by a hydraulic motor, it ensures product reliability, with a water spray pressure ranging from 4 to 6 MPa. The vibration discharge device utilizes hydraulic vibration principles to solve the problem of material adhesion, thereby reducing manual labor requirements.
