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 pumpThis 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 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.

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.

  • Adjustment of the metering rate directly in l/h or ml/h
  • Simple hose change
  • No problems with very gaseous media or air locks
  • Suitable for viscosities of up to 200,000 mPas (with VPT0530/VPT0565)
  • Sole contact with media in the hose
  • Many different control options, such as using an analogue 0/4-20 mA signal, contact controller, timer or via process control systems
