Turbulent or Smooth. You Decide.

From high-resolution printing to life-saving devices, our advanced flow technology delivers smooth, turbulence-free performance where precision is everything.

 


Smooth Flow Pumps – A Milestone in Diaphragm Pump Innovation

 

Our Smooth Flow series incorporates two advanced engineering approaches to achieve truly minimal pulsation. One design uses internal dampers integrated into the pump to absorb pressure fluctuations. The other relies on up to five diaphragms connected in parallel, each operating with a phase shift to smooth out the flow. Both configurations offer minimal vibration and noise and feature precise flow control via an integrated BLDC motor.

Key Benefits

Low Pulsation

Smooth Flow pumps reduce pressure pulsation to a minimum, thereby reducing vibrations, noise, and stress on all system components, resulting in a longer lifetime.

Gentle Liquid Handling

Minimal pulsation leads to a steady and smooth flow preventing cavitation, minimizing foaming and bubble formation.

Excellent Flow Controllability

The digitally customizable BLDC motor ensures a predictable flow with absolute precision in flow control, even at high speeds.
