Installation and Use
They re recommended for pumping clean water without abrasive parcticle and liquids that are chemically non aggresive to the material from which the pump is made.
The hydraulic characteristics of these pumps, together with their compactness, make them suitable for use in the industrial sector.
The pumps must be installed in enclosed places, or at least protected against inclement weather.
