The Grundfos CR 1-21 A-A-A-E-HQQE is a vertical, multistage, non-self-priming in-line 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 in stainless steel (EN 1.4301) for excellent corrosion resistance. A cartridge-type HQQE mechanical shaft seal ensures high reliability and ease of service. The pump is driven by a single-phase, fan-cooled asynchronous motor, making it suitable for a wide range of commercial, industrial, and water supply applications.
