The Grundfos 15SQE07-150 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 3/4HP Performance at 183.7 ft Head — Rated for 13.2 US GPM at 183.7 ft of head, ideal for deeper residential wells requiring consistent constant pressure delivery.

The 15SQE07-150 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 183.7 ft, this pump is well suited for deeper domestic wells requiring strong 3/4HP constant pressure output at higher lift demands.

The replaceable end cover with socket and direct-on-line start method make the 15SQE07-150 straightforward to service and commission, reducing installation time and long-term maintenance costs.
