Submersible pump SQ3-55 96510206

Multifunctional submersible pump for wells and tanks

The Grundfos SQ3-55 submersible pump is a reliable solution for supplying water to single-family homes, as well as for pumping water from tanks and irrigation systems. Its compact design and 74 mm diameter allow installation even in narrow openings with a minimum diameter of 76 mm. The construction based on floating impellers with carbide-ceramic bearings ensures long life and sand resistance – the pump can operate in water containing up to 50 g/m³ of contaminants.

Performance and reliability in every application

SQ3-55 is a single-phase pump with a power of 1.15 kW, capable of a maximum capacity of 3.9 m³/h and lifting water to a height of up to 74 meters. Built-in motor electronics protect it from various problems, such as dry running, overvoltage, voltage drops, overloads and overheating. The motor with permanent magnets guarantees optimal efficiency over a wide load range. In addition, the pump has a factory-installed check valve, which facilitates its installation and ensures proper operation.

Construction and materials for long-term operation

Made entirely of stainless steel (pump body made of stainless steel 304), the SQ3-55 pump is corrosion-resistant and provides long-term reliability. The length of the power cable is 1.5 meters, and the diameter of the pump is 74 mm. The ability to operate in a vertical or horizontal position (maintaining the appropriate angle of inclination) increases installation flexibility. The use of floating impellers minimizes the risk of damage caused by the presence of sand in the water, and electronic protections protect the motor against failures. The pump is designed for continuous operation (S1 mode) and has insulation class F to ensure safe use.
