2 K OUL-IMPLLR OUL-IMPLLR NTRIUL LTRI PUMPS WIT M/P INVRTR M/P INVRTR M-P ONSTRUTION TURS O T LTRONIS: M/P INVRTR The inverter continuously adjusts the rotation speed of the electric pump, keeping the pressure constant, even when the flow rate varies. The other electric pumps, also with variable speed, are activated in cascade after the first one has reached maximum speed. Through modulation, they compensate the pressure fluctuations of the system. or every operating cycle, it is possible to switch the restart to a different pump, therefore ensuring even use of all electric pumps. It is possible to set operation times for each individual pump, switching to another pump after such set times. The "SP" pressure can be adjusted by the user using the "+" and "-" keys found on the M/P (as a rule, all the pumps are set to the same pressure value). With the new M/P, it is sufficient to set the data on one of the devices, and it will be automatically propagated to the other pumps of the system.

The operating pressure can be adjusted by the user. good pressure set-point is between 1/3 and 2/3 of the maximum head of the electric pump. In this way, high efficient of the pump is maintained, together with maximum saving. In addition, the M/P does not block the pump if the pressure is not reached, but the flow is present. This prevents service interruptions in case of high flows. or more information refer to the technical appendix. PUMPS reserves the right to make modifications without notice. 17
