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 1B - PRO has a flow rate that varies from 50 to 350 litres per minute with a head from 18 to 5 metres.

The open impeller construction solution allows for the pumping of fluids relatively loaded with 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 for the circulation of cooling liquids.

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