INSTALLATION AND USE
Designed to transfer clean water free from abrasive particles and liquids that
will not damage the pump’s components. Highly reliable and quiet, they are
suitable for domestic applications.
They work seamlessly with pressure tanks, offering an ideal setup for all
irrigation requirements.
ELECTRIC MOTOR
The three-phase pumps are equipped with newly developed electric motors
designed to work with inverters, which guarantee stable and quiet operation.
Efficiency class IE3 for three-phase motors and IE2 for single-phase motors,
with class F insulation and IPX4 protection.
APPLICATION LIMITS
- Manometric suction head up to 7 m
- Liquid temperature between -10 °C and +60 °C
- Ambient temperature up to +40 °C
- Maximum working pressure 7 bar
