- Model C - Motor-Driven Metering Pump


Capacity range 8 – 76 l/h, 10 – 4 bar. The motor-driven metering pump Vario C delivers a high level of process quality for continuous metering within simple metering tasks. It can be used, for example, in the metering of additives or flocculants in chemical metering.

The basic pump for simple applications

With four gear reduction ratios, two dosing head sizes and four dosing head materials, the motor driven metering pump Vario C is well adapted to basic metering tasks. It is available with a 3-phase or 1-phase AC motor. Its pump capacity is adjusted via the stroke length, in 1% increments, with a self-locking rotary dial.

  • Excellent suction capacity, gentle metering stroke and consistently precise metering
  • Excellent process quality: Metering reproducibility is better than ± 2% within the stroke length adjustment range of 30 to 100%
  • Flexible adjustment of the pump capacity by means of the stroke length in 1% increments
  • Fibreglass-reinforced plastic housing
  • Good adaptation to the specific application, thanks to 4 different gear reduction ratios and 2 sizes of liquid ends in 4 material designs
  • Power end optionally available with three-phase or single-phase AC motor
