The Grundfos SQE 5-50 N is a 3" multi-stage submersible pump designed for domestic water supply, liquid transfer in tanks, irrigation, and environmental applications. It features “floating” impellers, each supported by a tungsten carbide/ceramic bearing for durability and long service life. The pump provides soft starting and integrated protection against dry-running, upthrust, overvoltage, undervoltage, overload, and overtemperature.
The motor is a single-phase permanent magnet rotor type (MSE3-N), delivering high efficiency across a wide load range and fitted with a replaceable end cover with socket. Variable-speed operation is possible when paired with CU300 or CU301 controllers.
