The Grundfos SQEN 5 series is a compact and high-efficiency 3" submersible bore pump range engineered for variable-speed operation in domestic, agricultural, and light commercial water supply applications. With a maximum flow rate of 80 LPM and advanced in-built motor protection, it offers flexible performance across various duty points — especially in low-yield or narrow-diameter bores.

Each pump features a permanent magnet motor, integrated frequency drive, and intelligent electronics, allowing soft start and full compatibility with Grundfos CU 301/300 control units for constant pressure operation. Designed with "floating" impellers and ceramic/tungsten carbide bearings, these pumps provide smooth, efficient operation and extended service life.
