GRUNDFOS CR3-4 A-A-A-E-HQQE 3X230 400 50HZ

CR 3-4 A-A-A-E-HQQEVertical  multistage centrifugal pump with suction and discharge ports on
same the level (in-line) enabling installation in a horizontal one-pipe system. The pump head
and base are in cast iron - all other wetted parts are in stainless steel. A cartridge shaft
seal ensures high reliability  safe handling and easy service and access. Power transmission is
via a split coupling. Pipework connection is via oval flanges with internal Rp threads.The pump
is fitted with a 3-phase  fan-cooled asynchronous motor.{br}Liquid:Liquid temperature range:-20
