/min. pump element mounted at
position 1 (AXX), with Ø 8 mm tube connection
(B), for rotary application (0002) with operating
voltage of 230 V AC and protection class IP55
(230VAC) gives the following order number:
KFG4 -5EOAXXB0002-230VAC
1) Notify us of the setting
times for the control unit.
2) System is designed
