The printing industry relies on accurate, contamination-free fluid handling systems to move inks, coatings, solvents, and cleaning fluids through various stages of the printing process. Whether for digital, flexographic, offset, or screen printing, pumps are essential to maintain colour consistency, reduce waste, and ensure smooth, uninterrupted press operations. Equipment must support both high-precision and high-speed environments while handling fluids of varying viscosities and chemical compositions.
Key Applications
1. Ink Transfer and Circulation
Inks must be pumped from bulk containers to press reservoirs or directly to print heads. Diaphragm, peristaltic, and gear pumps are commonly used for their ability to deliver a smooth, pulse-free flow while protecting the integrity of pigments and viscosity.
2. Coating and Varnish Application
Clear coatings, varnishes, and specialty finishes require consistent flow for even application. Pumps support both automatic and manual coating systems, ensuring that materials are applied uniformly and without contamination.
3. Solvent and Cleaning Fluid Handling
Cleaning print lines, rollers, and tanks involves the use of aggressive solvents. Magnetic drive or seal-less pumps are ideal for transferring these fluids safely, especially in ATEX-zoned environments where vapours pose a risk.
4. Dosing of Additives and Colourants
Precise dosing of additives—such as drying accelerators or colour enhancers—is critical to maintaining print quality. Metering pumps deliver controlled, repeatable dosing even at low flow rates.
