Compact pumping units, complete with electric pump, variable frequency driver, and pressure sensor.
Ideal for domestic and civic pressurization systems, the VSP pumping unit, thanks to its variable frequency driver speed regulator, allows modulating the motor speed according to the amount of water used by the system, reducing energy consumption and always keeping the system pressure constant, even when the number of points of delivery changes.
VSP runs particularly quietly thanks to smooth starts and stops that eliminate water hammering while drastically reducing power consumption.
Electronic Power Factor Corrector (PFC) technology ensures compliance with the most stringent European regulations by always providing the maximum performance stated on the rating plate, regardless of any, even significant, deviation of the supply voltage from the rated value (+/- 20%).
· Dry running
Microchip action stops the pump after a few seconds and attempts scheduled restarts to check water availability.
· Currents - voltages - temperatures
VSP limits currents, alerts if the voltage exceeds the allowed limits, and protects from overheating as well as short circuits between the output phases.
· Dynamic sensor monitoring
Continuous monitoring of the state of the sensors in the system allows VSP to dynamically adjust the operation of the pump and, in the event of faults, shut down the pumping unit.
