Description

The high efficiency and adaptability to the most varied applications, even anomalous ones, make it an ideal choice in the domestic, civil and industrial sectors; in particular for the distribution of water in combination with autoclave tanks, increasing the pressure in the network.

They are recommended for pumping clean water and liquids that are chemically non-aggressive for the materials from which the pump is made.

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