Blending unit for high process water quality

Finding the best blend for the right water quality

Your benefit

  • More flexibility and individuality
  • Easy commissioning thanks to the plug & play solution
  • Maximum process reliability

The right water quality can only be achieved by selecting the right components. We can provide the best-fit solution, whether based on a standard solution or an individually tailored system. We combine our expertise in applications knowhow with a tried-and-tested product portfolio to craft exactly the right blending unit to suit your purpose. Depending on requirements, the piping, the process control, the sensor system and the control valves can either be pre-assembled or individually configured from individual components.

Water Blending System



  • Plastic or stainless steel
  • Different process connector types possible (e.g. flange, thread etc.)


According to the blending technique that applies to the given application:

  • Flow sensor (proportional regulation)
  • Conductivity sensor (quality regulation)

Process controller:

  • Autonomous control system via pre-configured Bürkert controller – no integration into customer system needed
  • Alternative: customer-side PLC control (plant-side)


  • Pre-assembled and tested system for immediate integration into process (mounted on mounting plate)
  • Matched and tested individual components for individual integration into your process

Control valves:

  • Electric and pneumatic actuators possible
  • Precise control with each actuator type
