The SQ pump is Grundfos’ most compact submersible solution for ground water extraction.
A mere 3" in diameter, the long, lean pump fits nicely into small boreholes of the same size – or in 4" boreholes that over time have become smaller due to ochre deposits.
The compact design along with key features like dryrunning protection and soft start to reduce wear on motor makes the SQ pump one of the most reliable choices for submersible operation.
