Timer-based batch control
Applies to DME-AR and DME-AP
The set quantity is dosed in batches at maximum
capacity or the set capacity limitation.
The time until the first dosing (NX) and the following
sequences (IN) can be set in minutes, hours and days.
The maximum time limit is 9 days, 23 hours and 59
minutes (9:23:59). The lowest acceptable value is one
minute. IN must be higher than the time required to
perform one batch. If IN is lower than the time
required, the next batch will be ignored.
In case of supply failure, the set dosing quantity, the IN
time and the remaining NX time are stored. When the
supply is reconnected, the pump starts up with the NX
time at the time of the supply failure. Thus, the timer
cycle continues, but it will be delayed according to the
time of the supply failure.

Pulse-based batch control
Applies to DME-AR and DME-AP
The set quantity is dosed in batches at maximum
capacity or the set capacity limitation. The quantity is
dosed every time the pump receives an external pulse.
If the pump receives new pulses before the batch is
completed, these pulses will be ignored.

Anti-cavitation
When the anti-cavitation function is selected, the pump
extends and smooths its suction stroke. This results in
a softer suction stroke.
The anti-cavitation function is used in these situations:
• When pumping high-viscosity liquids
• When pumping degassing liquids
• When the suction line is long
• When the suction lift is high
Depending on the circumstances, the motor speed
during the suction stroke can be reduced to
approximately 75 %, 50 % or 25 % of the normal motor
speed. When using the anti-cavitation function, the
maximum pump capacity is reduced.
