INSTALLATION AND USE
They are recommended for pumping clean water and liquids that are chemically non aggressive to the materials from which the pump is made.
THIS SERIES IS SUITABLE FOR SUPPLYING AND MOVING WATER, IN COOLING, HEATING, CIRCULATING AND CONDITIONING SYSTEMS, FOR FIRE FIGHTING, IRRIGATION, INDUSTRIAL AND AGRICULTURAL APPLICATIONS.
Manifacture in accordance with dimensional standards EN 733 – DIN 24255 ensures models are fully interchangeable.The design allows the pump body to be removed without disconnecting it from the pipes (back pull out).
The pumps must be installed in enclosed places, or at least protected against inclement weather.
