For continuous delivery

The controller S-KG2 is recommended for continuous flow control in combination with the micro annular gear pumps mzr-2521, mzr-2921 and mzr-4622. The 4-Q-DC servo amplifier enables to control the constancy of flow rate via motor speed using the encoder mode of operation. Speed can be adjusted either with an external voltage signal (0…10 V), external current signal (4…20 mA) or an external potentiometer.

Advantages

  • Pump controller for continuous delivery
