Peristaltic Metering Pump DULCO flex Control - DFXa - Performance range extended

February 2021

ProMinent extends the performance range of the DULCO flex Control – DFXa to 65l/h at up to 5 bar back pressure in order to complete the product family of peristaltic metering pumps.. For small dosing quantities, the company offers a special variant.

The peristaltic metering pump DULCO flex control - DFXa is available in three versions: For metering 6 ml/h to 18 l/h (5bar), 10 ml/h to 30 l/h (7bar) and 22 ml/h to 65 l/h (5bar). The new 18 l/h variant is suitable for dosing little ml/h with high precision.

For all variants, the rotor speed of 100 rpm is very moderate, even at maximum feed rate. At this speed, tube compressions can be reduced which leads to long service intervals. In general, a peristaltic pump should be selected by the principle of “as large as possible”. The wide control range of 1:3,000 allows very slow speeds, and because of this, the service life can be extended even further. Suitable tube materials, and a pump design optimized for the application, ensure long service intervals. The number of interruptions in production or the process, due to tube changes, is therefore significantly lower.

Thanks to the combination of patented dosing head and tube changing process, programmed in the user interface, the pump allows for a quick and uncomplicated tube change, completely without tools. The display provides the operator with precise instructions about the steps to be completed when replacing the hose, preventing operating errors and saving costs.

The peristaltic metering pump is particularly suitable for metering outgassing, abrasive, shear-sensitive and highly viscous liquids. The results of extensive tests prove that the DFXa easily dispenses media with viscosities of up to 200,000 mPas!

At such high viscosities, peristaltic metering pumps clearly outperform diaphragm metering pumps.

The intuitive user interface, already known from ProMinent diaphragm metering pumps, ensures simple operation, and is identical across all ProMinent series.

Like other ProMinent metering pumps, the DFXa can be connected to the web-based fluid management platform DULCOnneX just within minutes. This cloud-based solution monitors dispensing processes in real time, can prevent downtimes, and generates fully automated reports. Digitally networked, it provides all necessary information for optimal system control and to ensure smooth processes.
