Description

The submersible pumps PEDROLLO of the NGA-PRO line are recommended for pumping water and liquids that are chemically non-aggressive to the materials making up the pump.

The PEDROLLO NGA 3B-PRO has a flow rate that varies from 100 to 900 liters per minute with a head from 19 to 8.5 meters.

The constructive solution of the open impeller allows to pump fluids relatively full of impurities without danger of clogging of the impeller. All the components in contact with the pumped liquid are in AISI 316 stainless steel. For this characteristic, the NGA-PRO series pumps are specifically used in washing plants for fruit, vegetables, fish, molluscs, in industrial plants for washing metal parts. , glass containers, circulation of coolants.

The installation must be carried out in closed places or in any case protected from bad weather.
