The Grundfos CR 1-7 A-FGJ-A-E-HQQE is a vertical, inline, multistage centrifugal pump with suction and discharge ports on the same level. The pump head and base are manufactured from cast iron, while all other wetted parts are made of stainless steel (EN 1.4301 / AISI 304), providing excellent corrosion resistance and durability. A cartridge-type HQQE shaft seal ensures high reliability, safe handling, and easy service access. Power transmission is via a rigid split coupling, and pipe connections are made using combined DIN, ANSI, and JIS flanges. The pump is fitted with a 1-phase, fan-cooled asynchronous motor, making it suitable for a wide range of commercial, industrial, and solar-driven water applications.
