STANDARDIZED MONOBLOC CENTRIFUGAL PUMPS (2-4 POLE)
NRM
RUGGED AND RESISTANT, WIDE RANGE, HIGH HYDRAULIC PERFORMANCE
The pumps in the NRM series are
monobloc single impeller models
with the hydraulic section and motor
connected by means of the housing, and
pump body constructed in compliance
with the standard EN733/DIN24255.
The pumps can be installed in all
positions, except for that with the
suction port directed upwards.
The Horizontal single impeller
• Central heating and air conditioning
systems.
• Collection of water from lakes, rivers,
wells.
• Gravity and sprinkler irrigation
systems.
• Water supply, fire fighting and
pressure booster systems.
