Why would you choose a GRUNDFOS SQ pump?
Let me tell you why. The SQ pump comes with:
Built-in dry running protection to increase reliability
Soft start functions to avoid overload
Voltage protection to handle a wide voltage range
And, by the way, the SQ pump is the easiest to install small submersible pump on the market. Perfect for replacements.
