The design of the open impeller allows for the pumping of liquids containing relatively high levels of impurities without the risk of clogging the impeller. The NGA pumps are particularly suitable for pumping liquids that are not completely clean, ensuring the passage of solid particles up to Ø20 mm. This makes them suitable for transferring water from canals, rivers, reservoirs, swimming pools, and for use in the industrial sector. Centrifugal pumps in this series are suitable for transferring liquids that are chemically non-aggressive to the materials from which the pumps are made. These pumps should be installed in enclosed spaces or in locations protected from atmospheric influences.
