Piston metering systems

Reliable metering with short cycle times

Piston metering units are used for processing 1K media, especially when short cycle times are required. All that is required is appropriate material supply and a metering calculator. The material is discharged in shot form at a freely configurable discharge rate or without interruption using a double piston system, e.g. in bead form. Different sizes are available depending on the requirements of the application. Combing two piston metering units together also enables 2K applications with this system. It is powered by a servo motor, with a spindle converting the rotational motion into linear motion, thus ensuring precise piston feed. Thanks to various design, there is practically no need for any maintenance work, which reduces service intervals and increases the durability of the products.

Product properties

  • Modular design enables a wide range of applications, variable mixing ratio and variable discharge rate
  • High precision thanks to metering and mixing at point of application
  • Multiple shots with one piston volume enable short cycle timesess reliability thanks to
    • High process reliability thanks to
    • Minimal dead space design
    • Venting at top of the metering chamber
    • Pressure monitoring in metering chamber
  • Reduced maintenance work thanks to
    • Specially guided metering piston
    • Backlash-compensating coupling between drive and metering piston
    • Hermetic sealing of piston with additional sealing liquid
