Close-coupled electrically driven centrifugal pumps
Application and Performance
Centrifugal, enbloc and single-impeller electrical pups with pump body, built to DIN 2155 - NF E 44-lll - UNI 7467 standards, with connection to the motor by means of a support unit. These machines are ideal for pumping clean water and other chemically and mechanically non-aggressive liquids. These systems can be installed in any position, provided the inlet opening faces, upwards, and thanks to their special design = which allows aback pull out of the motor and the rotary parts of the pump and subsequent re-assembly without having to remove the ump body and the pipes connected to it = can be easily and conveniently used for a wide variety of application in civil, agricultural, industrial or general plant uses: water supply, spray or flowing irrigation, autolave feed, high pressure system, heating, condition and any other general service requiring transfer of clean liquids.
