Grundfos CR3-10 A-FGJ-A-E-HQQE 1x220/240 50HZ

Vertical, 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 combined DIN-ANSI-JIS flanges.
The pump is fitted with a 1-phase, fan-cooled asynchronous motor.
