Un efficient ink circulation management in the flexographic industry, thanks to the use of proper pumping equiment, helps preventing material waste and ensures a continuous industrial operation.
Flexography is one of the most versatile and efficient technologies for producing high-quality packaging, labels, and printed materials. The profitability and efficiency of this process depend on a series of interconnected factors.
In this article, we’ll explore why choosing the ASTRAevo double diaphragm pump (DDE) is a strategic solution for ensuring an efficient, safe, and flawless printing process.
Process analysis and critical points
The main types of inks are classified based on their chemical composition and the type of substrate to be printed: water-based inks, solvent-based inks, and UV inks. We explored this topic in greater detail in a dedicated article on our blog about pumps for the flexographic sector, where we also examined ink transfer in relation to specific technical and system requirements.
Another key aspect we addressed concerns the chemical and physical properties of inks, which can vary significantly and have a direct impact on print quality. Among the most critical issues are fluctuations in pH and viscosity, as well as foam formation.
ARGAL’s response: why choose our pumps
Overcoming these challenges requires a well-engineered, specialized pumping technology, this is where ARGAL PUMPS solutions stand out, thanks to the ASTRAevo range of pneumatic double diaphragm pumps.
The range is available in three main configurations:
Standard configuration: the advanced diaphragm design allows the pump to handle fluids of varying viscosities effortlessly, maintaining consistent flow and ensuring precise transfer;
Low-pressure configuration: this version can start and operate at extremely low pressures, minimizing the risk of splashing and turbulence. It’s ideal for delicate applications or where controlled flow management is required;
ASTRAevo FREE: in this configuration, compressed air moves the fluid while an electrical signal regulates the speed. This system enables highly accurate dosing, perfect for automated environments or PLC-controlled systems. ASTRAevo FREE pumps can be easily integrated with a wide range of devices, allowing full process automation.
To further enhance performance, the optional PDE (dampener) system is available. Designed to reduce pulsation effects in the flow, it ensures greater operational stability. The ASTRAevo dampener line was developed to meet the precision and reliability demands of advanced printing processes.
Safety is non-negotiable: upon request, FDA-certified and ATEX-certified versions for Zone 1 or Zone 2 are available.
