Description

The PEDROLLO submersible pumps of the NGA-PRO 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-PRO has a flow rate ranging from 100 to 900 litres per minute with a head from 19.5 to 8.5 metres.

The open impeller design solution allows pumping fluids relatively full of impurities without the risk of clogging the impeller. All components in contact with the pumped liquid are made of AISI 316 stainless steel. For this feature, the NGA-PRO series pumps are specifically used in fruit, vegetable, fish and shellfish washing systems, in industrial systems for washing metal parts, glass containers and circulation of cooling liquids.

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