The peristaltic pump DULCOFLEX DFYa combines the properties of top products from the ProMinent product range

The new metering pump DFYa, the big brother of the DFXa, adds an intelligent peristaltic pump to the top capacity range of the ProMinent portfolio.

The new generation of peristaltic metering pumps can now be controlled electronically. It meters without the need for a valve and with a level of precision not previously possible. And yet it retains all the benefits of a peristaltic pump, which is why highly outgassing, high-viscosity, abrasive or shear-sensitive fluids, sometimes containing particles, can also be perfectly metered with the DFYa.

As with the DFXa, hose replacement on the DFYa is also assisted by the pump. When the hose needs to be changed, the pump displays exact instructions for the steps to be followed and automatically moves into the correct positions for hose replacement. The different hose materials (NR, NBR, NBR-A, EPDM Hypalon) enable the DFYa to work with a very wide range of media to be metered.

The peristaltic pump DFYa is simple to operate from the intuitive user interface with 4 keys and the click wheel. The DFYa thus joins the remaining ProMinent product range of intelligent metering pumps, which all share the same menu structure and user interface.

The new peristaltic metering pump offers various connectivity options and is IoT-capable. It can therefore be connected to the DULCONNEX IIoT solution, developed by ProMinent.
