GRUNDFOS 1/2HP 200-240V 50-60Hz Constant Pressure Well Pump | 10SQE05-110

The Grundfos 10SQE05-110 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.
• 1 1/4" NPT Outlet for Higher Flow Applications — Larger outlet connection supports increased system flow requirements compared to standard 3-inch submersible pump configurations.

The 10SQE05-110 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 2 m³/h (8.8 US GPM) and a rated head of 35 m (114.8 ft), this pump is well suited for domestic constant pressure applications requiring higher flow output at moderate head.

The replaceable end cover with socket and direct-on-line start method make the 10SQE05-110 straightforward to service and commission, reducing installation time and long-term maintenance costs.
