Peristaltic Metering Pump DULCOFLEX DFYa

3 variants with maximum flow rates of 200, 410 and 660 l/h at up to 8 bar back pressure

The valveless peristaltic metering pump DULCOFLEX DFYa delivers precise, linear and reproducible metering in all process conditions. It is highly suited to outgassing, viscose, shear-sensitive media, possibly containing particles – ProMinent is therefore setting new standards in metering with peristaltic pumps.

The Peristaltic Metering Pump DULCOFLEX DFYa Is the Only One of Its Kind That Can Be Controlled Totally Electronically and Features a Fibre-Reinforced Hose and a Display

The DFYa metering pump product range adds 3 intelligent peristaltic pumps with a maximum capacity of 200, 410 and 660 l/h to the top capacity range of the ProMinent portfolio.

The DFYa peristaltic metering pumps can 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 is therefore a new addition to rest of the ProMinent product range of intelligent metering pumps, which all share the same menu structure and user interface.

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