Why Choose a SQ 3-65?

The SQ 3-65 is often considered the go-to pump for rural properties because it provides enough flow for a family home while still offering excellent pressure for elevated tanks, long pipelines and stock watering systems. It's a great balance between the smaller SQ 2-55 and the larger SQ 5-70.
