Product description

A peristaltic pump that brings together the best qualities 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, with full use of the properties of a peristaltic pump This is how they work: The feed chemical is pumped by the rotor clamping the hose ... more in the glossary. 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 exchange technique. 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 This is how they work: The feed chemical is pumped by the rotor clamping the hose ... more in the glossary.

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 6 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)
Hose connectors:	PVDF/PTFE
Metering reproducibility:	±2% 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.

All data calculated with water at 20 °C.
