As a result of its lower starting current, the Grundfos SQ has a soft-start which gradually ramps the pump up to nominal speed over 2-3 seconds. This protects against water hammer and upthrust without sacrificing torque. In addition, soft-start reduces wear on pump and motor components and ensures reliable start-up even when voltage is low.
