Description

The NK 4/4 submersible electric pump from the NK series by Pedrollo is solid and resistant.

Pedrollo used AISI 304 and AISI 431 stainless steel for a construction built to last over time.

It can pump clean water and liquids that are chemically non-aggressive for the components.

The NK 4/4 is recommended for domestic, agricultural, and industrial applications. It is particularly suitable for water distribution in conjunction with pressure tanks, for irrigation of vegetable gardens and gardens, and for pressure boosting.

It must be installed vertically up to a maximum of 20 metres below the water level.
