Grundfos SQ Bore Pump – 2-70
Not every bore system needs variable speed control.
The Grundfos SQ 2-70 is a fixed-speed submersible bore pump designed for reliable water supply where pressure is managed separately.
It’s commonly used in domestic and light commercial bore systems where durability, efficiency, and straightforward control are preferred.
What this is used for
The Grundfos SQ 2-70 is used in clean water bore applications where a dependable submersible pump is required.
- Domestic bore water supply
- Garden and irrigation systems
- Water transfer and pressure systems using external controllers
- Installations where fixed-speed operation is suitable
What to check before you buy
- Bore suitability: Confirm bore diameter, depth, and yield match the pump duty.
- Required flow and head: Ensure the pump curve suits your system design.
- Power supply: Single phase 200–240 V, 50/60 Hz.
- Pressure control: This is a fixed-speed pump. Pressure is typically managed via an external controller or pressure tank.
- Water quality: Designed for clean water. Filtration may be required depending on bore conditions.
Important system note
Fixed-speed bore pumps rely on correct system design. Incorrect sizing or control can lead to cycling, pressure fluctuation, or reduced pump life.
