Calculating Efficiency Fall-Off Guide

 

SQ

Grundfos SQ pumps are compact submersible pumps, designed for domestic groundwater supply for private housing, small waterworks, and small irrigation systems.

The Grundfos SQ is a compact 3” multistage centrifugal pump, which can be installed in boreholes that are 3” or larger. Featuring built-in electronics, it is simple to install and operate and guarantees a reliable water supply at all times. The SQ submersible groundwater pumps are equipped with permanent magnet motors and can supply pump heads up to 200 m.

The single high-speed SQ submersible groundwater pump is suitable for both continuous and intermittent operation for a variety of applications, including domestic water supply, small water works, irrigation and groundwater lowering.

Thanks to its high-speed permanent magnet motor, the SQ pump offers high performance in relation to its compact design. Dry-running and overload protection safeguards against liquid absence and unstable motor supplies. Built-in electronics make SQ very easy to install and operate. Its corrosion-resistant stainless steel ensures the SQ groundwater pump a long, reliable life, providing you with peace of mind.

SQE

Grundfos SQE pumps are compact submersible pumps, designed for constant pressure applications within domestic groundwater supply for private housing, small waterworks, and small irrigation systems.

The SQE submersible groundwater pump is one of the most advanced submersible pump solutions for domestic applications. Equipped with a permanent magnet motor and a built-in variable speed drive, it enables performance adjustments by means of communication with an external control box.

SQE features a variable speed drive, which helps the pump to automatically adjust itself to ensure constant water pressure regardless of changing demands, eliminating weak or fluctuating water supply and improving comfort. SQE is provided as an all-in-one box solution, easy to both install and operate. It is suitable for continuous and intermittent operation for a variety of applications, including groundwater supply and pressure boosting.

Thanks to the built-in variable speed drive, SQE delivers constant water pressure regardless of the number of opened taps. This increases homeowner comfort. SQE has a very wide supply voltage range which reduces the risk of overheating the motor, improving your peace of mind. Its soft start feature minimises the risk of pump wear and reduces the occurrence of water hammer in the pipes, resulting in an increase of the overall lifetime of your SQE.
