The Grundfos CR 3-7 A-FGJ-A-E-HQQE is a vertical, multistage centrifugal
inline pump engineered for reliable performance in commercial, industrial,
agricultural, and solar water systems. Designed with suction and discharge
ports on the same level, this inline configuration allows easy installation in
space-saving pipe layouts.
The pump head and base are manufactured
from robust cast iron, while all other wetted components are made of
corrosion-resistant stainless steel (EN 1.4301 / AISI 304). A high-quality
cartridge shaft seal (HQQE) ensures operational safety, high reliability, and
simplified servicing. Power transmission is achieved through a rigid split
coupling, and the unit is equipped with a single-phase, fan-cooled
asynchronous IEC motor. Combined DIN / ANSI / JIS flange connections provide
excellent flexibility across global standards. With drinking water approvals
and a wide temperature and pressure range, this pump is ideal for pressure
boosting, water treatment, irrigation, and solar water supply applications.
