Description

It is recommended for pumping clean water without abrasive particles and liquids that are chemically non-aggressive for the materials from which the pump is made.

Built in RYTON with a brass front cover on the impeller, it offers a safe guarantee against the formation of rust and oxidation; for these characteristics it is recommended for use in the industrial sector, for example for cooling, air conditioning, ironing systems, etc.

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