Work Principle
Our advanced cast iron pressure filter ingeniously introduces the liquid between filter plates and cloth. Under pressure, liquids seamlessly pass through the filter cloth while solids form a filter cake. Once filtration concludes, efficient mechanical unloading is effortlessly enacted.
Maintenance and Care
Conduct regular inspections to ensure all connecting parts and seals remain intact, proactively preventing any potential water leakage.
Meticulously clean the filter cloth and plates after each use to prevent residue and maintain optimal performance.
Ensure smooth operation by consistently lubricating moving parts, maintaining peak performance.
Summary
The cast iron pressure filter, with its robust build and superior performance capabilities, is an indispensable asset for industrial solid-liquid separation. Adhering to proper usage and maintenance not only boosts production efficiency but also significantly lowers operational costs, making it an investment in excellence and sustainability.
