INSTALLATION AND USE
They are recommended for pumping water and liquids that are chemically non aggressive to the materials from which the pump is made.
THE OPEN IMPELLER DESIGN ALLOWS THE PUMPING OF LIQUIDS WITH RELATIVELY HIGH LEVELS OF IMPURITIES WITHOUT RISK OF CLOGGING THE IMPELLER. FOR THIS REASON THE NGA SERIES ARE SUITABLE FOR USE IN INDUSTRY, FOR THE TRANSFER OF WATER FROM CANALS, RIVERS, RESERVOIRS, TANKS, ETC.
The pumps must be installed in enclosed places, or at least protected against inclement weather.
