Peristaltic Pump DULCOFLEX DFXa

Feed rate of 10 ml/h to 65 l/h at up to 7 bar back pressure

DULCOFLEX DFXa meters outgassing, viscous, abrasive or shear-sensitive media and is setting new standards in metering. Linear and reproducible metering (± 1 %) is guaranteed with this peristaltic pump under all process conditions. Hose replacement is a very simple process.

A Peristaltic Pump That Brings Together The Best Gualities of ProMinent Metering Pumps.

The new DULCOFLEX DFXa meters reliably and is simple to operate. This sees the addition of an intelligent peristaltic metering pump to the ProMinent product range. ProMinent is making use of its decades-long experience in the metering pump sector to bring together the best of two worlds. Valve-free metering with the accuracy of a diaphragm metering pump, tapping into all the properties of a peristaltic pump. The applications of this metering pump include very outgassing, high-viscosity, abrasive, shear-sensitive or chemically aggressive fluids.

The liquid end developed and patented by ProMinent makes quick and straightforward hose replacement possible with a unique change concept. The display provides the fitter with precise instructions about the steps to be completed when replacing the hose. The high-performance hoses used guarantee exceptional chemical resistance and a long service life.

The order information required for hose replacement can be found on the pump’s operating menu.

The intuitive user interface with click wheel ensures simple operation of the peristaltic pump.

A brushless direct current motor forms the heart of the DULCOFLEX DFXa. Its ingenious control provides for precise metering and reduced pump capacity with continuous metering up to 10 ml/h. What’s more, the new peristaltic metering pump is IoT-enabled, meaning that it can be fully networked and connected to the DULCONNEX IIoT solution developed by ProMinent.

Hose material: Thermoplastic vulcanisate (TPV), polyurethane (PUR), SEBS
Hose connectors: PVDF/PTFE
Metering reproducibility: ±1% with retracted hose (after approx. 200 revolutions)
Electrical connection: 100 – 230 V ±10%, 50/60 Hz
Nominal power: approx. 50 W
Degree of protection: IP 66, NEMA 4X Indoor
Permissible ambient temperature: 0 … 45 °C
Viscosities: The DFXa0530VPT and DFXa0565VPT have successfully metered viscosities of up to 200,000 mPas in testing. If metering media with higher viscosities, it is important that you use solid pipework with a large diameter (DN 10). The pipes should also be as short as possible. Also do not allow the pump to run at full output.

All data calculated with water at 20 °C.
