Prominent DULCOFLEX DFXa Peristaltic Pump

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

The DULCOFLEX DFXa is a pipeline pump with a peristaltic pump design that offers ±1% accuracy and consistency. It can be used to meter a wide range of fluids, which makes it ideal for metering sensitive materials. Quick and straightforward hose changes are possible.

Product Description

The DULCOFLEX DFXa is a min intelligent peristaltic pump with the precision of a diaphragm metering pump for valveless metering. It is suitable for metering outgassing, highly viscous, abrasive, shear sensitive and chemically aggressive liquids.

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 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.
