Put into operation

8.1

Venting

1. Charge the system appropriately and ventilate.
▶ The pump is self-ventilating.
8.2

Flush

CAUTION
Damage to property!
While using fluids with admixtures, property damage can occur due to the accumulation of
chemicals.
• Flush system before commissioning.
• Flush out the pump before pouring in, refilling or replacing fluid.
• Remove the pump before change in pressure flushes.
• Do not perform any chemical flushes.

Description
The control changes the differential pressure setpoint to be maintained by
the pump linearly between reduced differential pressure H and H
The controlled differential pressure H decreases or increases with the flow
rate.
The speed of the pump is kept at a set constant speed.
The control keeps the differential pressure created by the pump constant
above the permitted flow rate at the selected differential pressure setpoint
H up to the maximum characteristic curve.
