Introducing the Dazhang Program-controlled automatic high-pressure water washing filter press, a marvel of modern engineering. This product enhances the capabilities of the standard machine by integrating an advanced high-pressure washing system, specifically designed to cleanse the press cloth with precision and efficiency.
In cases where the filter cloth becomes obstructed, the sophisticated cloth washing system seamlessly clears away any solid blockages using high-pressure water, thereby accelerating the filtering process and extending the lifespan of the equipment. The device is available in two distinct configurations: the efficient Single Pole Washing System and the robust Double Poles Washing System.
With a maximum design pressure of 6mpa, this device offers flexibility through its various types: the streamlined Single Pole Washing System, the powerful Double Poles Washing System, and the versatile Scroll Scrubbing System, each tailored to meet diverse operational needs.
