The Grundfos 10SQ10-290-230V is a 3 inch stainless steel submersible well pump rated for 10 GPM, 1 HP, 230V single-phase power, and a 2-wire connection. Its SQ motor design combines permanent-magnet technology with an integrated electronic unit for efficient operation and soft start performance.
Floating impellers and tungsten carbide/ceramic bearings provide wear resistance in sandy conditions. Built-in protections include overvoltage, undervoltage, overload, overtemperature, and upthrust protection. This model does not require a control box.
This model is rated for 10 GPM, 1 HP, 230V, single-phase power, and a 2-wire connection.
What is the pump diameter?
The pump has a 3 inch diameter.
Does this pump need a control box?
No. The product data states that no control box is required.
What motor technology does it use?
It uses a permanent-magnet motor with an integrated electronic unit and Grundfos micro-frequency converter technology.
Does the pump include soft start?
Yes. The integrated electronic unit provides soft starting for smooth and steady acceleration.
How is the pump designed for sandy conditions?
It uses floating impellers and tungsten carbide/ceramic bearings for high wear resistance to sand.
What protections are built into the pump?
The pump includes overvoltage, undervoltage, overload, overtemperature, and upthrust protection.
What is recommended for wells with high static water levels?
The source recommends using a flow restriction valve and restricting maximum flow to the pump's recommended operating range to help prevent upthrust damage.
