Description
The Grundfos 15SQE05-110 is a 3-inch multi-stage submersible well pump designed to provide constant pressure for domestic water supply, liquid transfer, irrigation, and environmental applications.
The Grundfos CU302 Constant Pressure Controller is required for this pump to operate as a constant pressure system and is sold separately.
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 Soft Start Technology — Fully submersible motor with soft starting capability reduces mechanical stress and extends overall pump service life.
- High-Flow 15 GPM Class Performance — Rated for 13.2 US GPM at 137 ft of head, delivering robust constant pressure output for higher-demand residential installations.
The 15SQE05-110 is constructed 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 13.2 US GPM and a rated head of 137 ft, this pump is well suited for higher-demand domestic constant pressure systems requiring strong flow output at moderate well depth.
The 2-wire design, replaceable end cover with socket, and direct-on-line start method make the 15SQE05-110 one of the easiest pumps in its class to install and commission on site.
