Centrifugal pumps with open impeller
PERFORMANCE RANGE
INSTALLATION AND USE
•
•
Suitable for use with liquids that are not chemically aggressive towards the materials from which the pump is made.
The open impeller design allows liquids containing relatively
high levels of impurities to be pumped without the risk of the impeller clogging. As a result of these characteristics the NGA series
pumps are used specifically in industry and for transferring water
from canals, rivers, reservoirs, tanks, etc.
The pump should be installed in an enclosed environment, or at
least sheltered from inclement weather.
Flow rate up to 350 l/min (21 m³/h)
Head up to 20 m
