12.3 Adjustment modes
1 – Constant speed I, II, III (traditional mode):
The pump operates at a constant, pre-set speed. This is the standard operating mode of the pump
in the Fusion Hybrid Oil module at speed II.
2 – Variable differential pressure (
∆
p-v):
The setpoint value of the differential pressure H increases in a straight line between ½H and H
within the permitted flow margin. The differential pressure generated by the pump is adjusted to
the appropriate setpoint value of differential pressure.
3 – Constant differential pressure (
∆
p-c):
The adjustment keeps the discharge height adjusted independently of the flow rate.
4 – Setting the adjustment mode
