Description product group

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, 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.
