NGA 3B - Centrifugal electric pump with three-phase open impeller
Flow rate up to 840 l / min (50.4 m³ / h). Head up to 16.5 m. 1.8 Kw (2.5 HP) engine.
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 3B has a flow rate that varies from 100 to 840 liters per minute with a prevalence from 16.5 to 7 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.
