Varnish Diaphragm Pump for Printing,Domestic Alternative to Imported Pumps,Direct Replacement for European & American Original Coating Pumps.

This Varnish Diaphragm Pump is an innovative fluid transportation device specially developed for printing UV and water-based coating processes. Optimized for varnish corrosion, gelling and bubbling problems, it achieves full domestic substitution of imported European and American original pumps. Adopting upgraded composite PTFE diaphragm, the pump features excellent solvent resistance, anti-swelling and ultra-long service life, effectively solving the common failures of traditional pumps such as easy damage and frequent shutdown. The optimized low-pulsation flow channel ensures stable pressure and uniform varnish output, significantly improving coating flatness and printing yield. The modular quick-disassembly structure greatly reduces maintenance time and spare parts cost, helping printing factories cut operating costs and production downtime. Widely used in color box, cigarette package, label, flexible packaging and corrugated coating lines, it is a high-end and cost-effective upgrading solution for printing fluid system replacement.
