FIELD: pumps.
SUBSTANCE: present invention relates to a method for operation of a dual-structure circulation pump, wherein the circulation pump comprises at least two divided separate pumps, the discharge nozzles whereof converge into a single discharge nozzle, and at least one switching valve installed in the discharge nozzle is provided for switching between the single-pump and multi-pump operation modes, wherein adjustment of the circulation pump determines individual adjustment values for the drives of at least two separate pumps in the multi-pump mode in order to stabilise the position of the valve.
EFFECT: ensured operation of a dual-structure pump.
