Grundfos SQE Constant Pressure Bore Pump – 2-70

In bore water systems, fluctuating pressure is one of the most common frustrations.

The Grundfos SQE 2-70 is a variable speed submersible bore pump designed to maintain steady water pressure as demand changes.

By adjusting pump speed automatically, it delivers consistent pressure while reducing pump cycling and wear.

What this is used for

The Grundfos SQE 2-70 is used in clean water bore systems where constant pressure and reliable operation are required.

• Domestic water supply from bores
• Pressure boosting for homes and small buildings
• Garden and irrigation supply with varying demand
• Installations requiring smooth, consistent pressure

What to check before you buy

• Bore suitability: Confirm bore diameter, depth, and yield suit the pump duty.
• Required flow and head: Ensure the pump curve matches your system requirements.
• Power supply: Single phase 200–240 V, 50/60 Hz.
• Water quality: Designed for clean water. Filtration may be required depending on bore conditions.
• Control setup: SQE systems rely on compatible controllers and sensors for constant pressure operation.

Important system note

Correct sizing and setup are critical with variable speed bore pumps. An incorrectly selected pump can lead to poor performance or shortened service life.
