EPQ series membrane pumps

Our most commonly used pump system is the EPQ 200.

The EPQ 200 ink handling system helps flexographic printers to assure a consistent print quality. The system is specifically designed for closed chamber doctor blades systems and works on a two-pump principle.

The dedicated low-pulsation ink supply pump with integrated volume flow control makes sure that the ink flows steadily to the chamber. By means of the dedicated ink return pump, the amount of ink in the chamber can be controlled to avoid overpressure, which could have a negative impact on the ink transfer from the chamber to the anilox roller.

To facilitate cleaning of the chamber, the flow direction of the supply pump can be inverted, which means that the chamber gets actively emptied by two pumps. This way, the ink evacuation is much faster and less ink residue remains in the chamber compared to gravity return. Additionally, the EPQ 200 allows to flush cleaner through the cycle so that little manual cleaning will be necessary.

All typical flexo solvents, water-based and UV ink types can be handled with the EPQ 200. When used with solvent based inks, the pumps will be ATEX-certified and equipped with groundable parts.

The integration of the ink handling system with the press is extremely straightforward, since the EPQ 200 comes as a compact enclosure with all pump units inside. The enclosure can either be wall-mounted at the press or placed on an optional stainless-steel frame, putting the operation interface at ergonomic work height. Depending on the amount of printing decks to be supplied, up to 4 pump units can be stored in one enclosure to save floor space.

The advantages of the EPQ 200 ink handling system in a nutshell:

• It assures a balanced ink supply for consistently high print results
• It is easy to operate
• It facilitates the cleaning process of the chamber system
• It offers very low start-up and running costs
