TOP MULTI-TECH 4 - 1 HP multi-impeller electric pump with press control
Flow rate up to 80 l/min (4.8 m³/h). Head up to 52 m. 0.75 Kw (1 HP) motor.
With integrated electronic device that allows you to start or stop the electric pump automatically by opening or closing the tap.
The TOP MULTI-TECH 4 multi-impeller electric pump by Pedrollo is recommended for domestic and civil use.
Recommended for pumping clean water and liquids that are not chemically aggressive towards the materials from which the pump is made.
A special feature of the TOP MULTI-TECH 4 is the internal electrical device that starts the electric pump following a drop in system pressure below 2.5 bar and stops it when the flow drops below 3 litres per minute.
This device protects the pump from dry running and blocking, in fact after 48 hours of inactivity it starts the pump for 10 seconds.
The TOP MULTI-TECH 4 is suitable for domestic water supply from relatively deep basins, tanks or wells, for drawing rainwater from cisterns for hand watering or to feed an irrigation system.
The flow rate ranges from 10 to 80 liters per minute. The head ranges from 8 to 52 meters.
It must be powered by a single-phase voltage, has a horsepower of 1 HP and the temperature of the liquid to be pumped ranges from -10 degrees centigrade up to +40.
