Controller S-KB-4

For continuous delivery

The controller S-KB-4 is recommended for continuous flow control in combination with micro annular gear pump mzr-7241. The 2-Q-DC servo amplifier enables to control the constancy of flow rate via motor speed using the hall sensors of the brushless DC-motor. Speed can be adjusted with an external voltage signal (0 … 10 V).
