PEDROLLO HF Centrifugal Pumps User Guide
PERFORMANCE RANGE
- Flow rate up to 700 l/min (42 m3/h)
- Head up to 39 m
INSTALLATION AND USE
Designed for civil and agricultural use.
Their high-efficiency levels and capability for continuous operation make them
an ideal choice for furrow and sprinkler irrigation, in addition to drawing
water from lakes, rivers, and wells. They are also suitable for a wide range
of industrial applications that require substantial flow rates at medium-low
head pressures.
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 +90 °C
- Ambient temperature up to +40 °C
- Maximum working pressure:
