Description

The PEDROLLO pumps of the NGA line are recommended for pumping water and liquids that are chemically non-aggressive for the materials from which the pump is made.

The PEDROLLO NGA 3B has a flow rate ranging from 100 to 840 litres per minute with a head of 16.5 to 7 metres.

The open impeller design solution allows pumping fluids relatively loaded with impurities without the risk of clogging the impeller. For this feature, the NGA series pumps are used in industry, in the transfer of water from canals, rivers, tanks, basins, etc.

Installation must be carried out indoors or in any case protected from the elements.
