A450 Eureka™ - Medium Volume Simultaneous Tinting

A450 Eureka™ – Simultaneous


A450 Eureka™ – Medium Volume Simultaneous Colorant Dispenser

The A450 Eureka™ incorporates HERO’s patented Progressive Cavity Pump (PCP) dispensing technology. This innovative and revolutionary pump design allows HERO to offer the first truly low maintenance automatic colorant dispenser. In fact, we believe it offers the lowest cost of ownership available on the market today. The A450 Eureka™ incorporates this PCP technology into its unique cartridge design pump which allows for quick, clean and simple replacement. In addition, the A450 Eureka™ further reduces yearly maintenance costs as it does not suffer calibration drift like other competing technologies.

Thanks to this technology’s ability to reverse the flow of colorant through the pump, HERO has also solved the problem of colorant drying in the nozzle. This feature is referred to as pull back. At the end of each dispense, the pump reverses rotation “pulling” back the colorant inside the nozzles. This minimizes contact of colorant with air.

The A450 Eureka™ dispenses up to four colorants simultaneously and offers precision unmatched by its rivals. On average dispenses, the accuracy is within +/-1%.   Yes, this unit is so precise it can be used to tint sample color testers!


  • Unbeatable precision and productivity (better than a gear pump system)
  • Unmatched durability and low maintenance cost (similar to a piston pump system)
  • Simple to repair – a complete dispense circuit can be replaced in less than 15 minutes without the need for special tools or training
  • Drift free calibration
  • Simple to use
  • Unbeatable quality/price ratio
  • New cartridge pumps for quick and clean pump replacement
  • Simultaneous dispense – 4 channels (colorants) at once – max dispense rate of up to 50 ounces per minute!


  • Eliminates cost of repeated calibrations and repairs for which other technologies require a service technician
  • Capable of dispensing difficult products
  • Colorant drying in the nozzles will be a thing of the past
  • Improved durability and pump life compared to gear drive units


  • Sturdy sliding shelf for computer with monitor and other accessories
  • Refill threshold is ideal for staff of any height
  • Electrically powered can shelf makes it easy to tint different can sizes
  • Space saving compact design
