Grundfos SQ 3-55 Submersible Pump – a reliable water source

The Grundfos SQ 3-55 submersible pump is a compact, multi-stage centrifugal unit with a diameter of 3 inches, designed for installation in openings with a minimum diameter of 76 mm. Its construction and built-in electronic system ensure easy installation and trouble-free operation, guaranteeing a constant access to water. It is a solid solution for both single-family homes and small water supply installations or irrigation systems.

Performance and application

The SQ 3-55 pump offers a maximum capacity of 3.9 m³/h, and its 1.15 kW motor provides efficient water lifting even to a height of up to 56 meters (corresponding to a pressure of 549.03 kPa). This makes it ideal for:

• Supplying groundwater for private homes and small installations.
• Pumping water into tanks.
• Increasing pressure in existing water supply systems.
• Environmental applications, such as dewatering or water sampling.
• Supplying garages and gas stations.

The pump is suitable for both continuous and intermittent operation, which increases its versatility.

Construction and characteristics

The SQ 3-55 is designed for durability and reliability. The pump housing is made of stainless steel (grade 304 – 1.4301), which ensures corrosion resistance and long life. The impeller made of a material other than stainless steel (details unspecified) provides optimal pumping performance even in water containing small amounts of sand – the pump tolerates up to 50 g/m³. In addition, the pump has a built-in check valve to prevent backflow and a 30-meter long cable to facilitate installation. Insulation class F guarantees safe operation of the motor in various environmental conditions, and protection class IP68 ensures complete sealing against immersion and dust. The motor speed is 10700 revolutions per minute, which translates into high energy efficiency. The nominal operating mode S1 means the possibility of continuous operation without the risk of overheating. The connection on the outlet side is a tapered internal gas thread BSPP-G (ISO 228-1) with a diameter of 1 ¼ inch (32 mm).
