The Grundfos 15SQ05-110-115V is a 3 inch stainless steel submersible well pump rated for 15 GPM, 1/2 HP, 115V single-phase power, and a 2-wire connection. Its SQ motor design uses permanent-magnet technology with an integrated electronic unit for efficient operation and soft start capability.
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.

What size is the pump?
The pump has a 3 inch diameter.
Does this pump require a control box?
No. The product data states that no control box is required.
What type of motor does it use?
It uses a permanent-magnet motor with an integrated electronic unit and Grundfos micro-frequency converter technology.
Is this pump designed for sandy conditions?
Yes. 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.
Does the pump have soft start?
Yes. The integrated electronic unit provides soft starting for smooth acceleration.
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.
