4.13 Batch
The pump is dosing the set quantity in batches at the
maximum capacity or the set maximum capacity, see
section 4.15.
The quantity is dosed every time the pump receives
an external pulse.
If the pump receives new pulses before the previous
batch is performed, these pulses will be ignored.

The setting range is the same as for Timer, see sec-
tion 4.12.

4.14 Anti-cavitation
The pump features an anti-cavitation function. When
this function is selected, the pump extends and
smooths its suction stroke, resulting in softer prim-
ing.
The anti-cavitation function is used:
• when pumping liquids of high viscosity,
• in the case of a long suction tube and
• in the case of a high suction lift.
The maximum pump capacity is reduced when this
function is selected. See section 2.1 Mechanical
data.
