INSTALLATION AND USE
They are recommended for pumping clean water without abrasive particles and liquids that are chemically non aggressive to the materials from which the pump is made.
NON-FERROUS CONSTRUCTION WITH WETTED PARTS IN HIGH PERFORMANCE TECHNOPOLYMER AND BRASS TO ELIMINATE THE POSSIBILITY OF CORROSION. CONSEQUENTLY THEY ARE RECOMMENDED FOR INDUSTRIAL APPLICATIONS INCLUDING COOLING, CONDITIONING AND BOILER FEED.
The pumps must be installed in enclosed places, or at least protected against inclement weather.
