Description
The PEDROLLO pumps of the NGA line are recommended for pumping water and liquids that are chemically non-aggressive to the materials making up the pump.
The PEDROLLO NGA 1A has a flow rate that varies from 50 to 350 liters per minute with a prevalence from 19.5 to 6 meters.
The constructive solution of the open impeller allows to pump fluids relatively full of impurities without danger of clogging of the impeller. For this characteristic, the NGA series pumps are used in industry, in the transfer of water from canals, rivers, tanks, basins, etc.
The installation must be carried out in closed places or in any case protected from bad weather.
