The Grundfos 5SQE05-90 is a 3-inch multi-stage submersible well pump designed to provide Constant pressure for domestic water supply, liquid transfer, irrigation, and environmental applications.

Key Features

• Permanent Magnet Rotor Motor (MSE3) — Delivers optimum efficiency across a wide load range while maintaining consistent constant pressure performance.
• Floating Impeller Design with Tungsten Carbide/Ceramic Bearings — Each stage features its own independent bearing, maximizing durability and reducing wear under continuous operation.
• Comprehensive Built-In Motor Protection — Guards against dry-running, upthrust, overvoltage, undervoltage, overload, and overtemperature for worry-free operation.
• IP68-Rated Enclosure with Internal Thermal Protection — Fully submersible motor with built-in thermal protection ensures long-term reliability in demanding well environments.
• Built-In Non-Return Valve — Integrated check valve prevents backflow, protecting the pump and maintaining system pressure at all times.

The 5SQE05-90 is engineered from stainless steel AISI 304 throughout both the pump and motor housing, delivering superior corrosion resistance for long-term submersible installation.

With a rated flow of 4.4 US GPM and a rated head of 111.6 ft, this two-stage pump is perfectly sized for residential constant pressure systems requiring reliable, efficient performance.

Compatible with Grundfos CU 300/CU 301 controllers, the 5SQE05-90 integrates seamlessly into smart water management systems for enhanced monitoring and control capability.
