SQ pumps are designed for pumping thin, clean, non-aggressive and non-explosive liquids that do not contain mechanical or fibrous impurities. Grundfos SQ series pumps are made of AISI 304 stainless steel, which is suitable for the pump's contact with drinking water.
The pump is supplied with a 1 m cable.
The pumps are suitable for continuous operation and are ideal for a wide range of applications:
The SQ pump is ideal for ensuring water supply in the private sector, especially in single-family houses and cottages that are not connected to the public water mains.

The pumps are protected against dry running. If there is an insufficient amount of water in the borehole, the pump switches off automatically, preventing overheating and damage to the motor winding. However, this function serves only as emergency protection. In the event of low borehole yield, the pump must be supplemented with external level monitoring.
The electrohydraulic design ensures high efficiency for this pump, which is reflected in low electricity consumption and therefore also low operating costs. The motors are designed according to the permanent magnet principle (PM motor). This is the most advanced type of synchronous electric motor, characterised by high efficiency and reliability across a wide performance range. The same type of motors is also used, for example, in electric cars. Reliability and efficiency are further supported by auxiliary elements such as:
The pumps can be installed in vertical and horizontal positions, as well as in all intermediate positions.
