Installation and Use
They are recommended for pumping water and liquids that are chemically non aggresive 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 pro-nga series are suitable for use in systems for washing fruit., vegetables, fish, shellfish, meat, in industrial systems for washing metal parts, glass containers, and for the circulation of cooling liquids.
The pumps must be installed in enclosed places, or at least protected against inclement weather.
