Which is better for pressure boosting a house?

The Pearl Thor15. It publishes a 35-40 psi optimum range and a 125 psi maximum working pressure, which is what a booster setup needs. The AQUASTRONG lists no pressure rating.

Which moves more water for sprinklers?

The AQUASTRONG SPRK150, at a 4,250 GPH maximum versus the Pearl's 40-60 GPM optimum. Its 2" suction inlet also feeds the pump more freely.

Which has the deeper suction lift?

The Pearl Thor15 states a 25 ft maximum suction lift. AQUASTRONG lists 108 ft as maximum lifting height, which reads as total head rather than suction lift, so the Pearl figure is the one to trust for priming depth.

Is the AQUASTRONG worth extra money?

Only if you need its higher flow and 2" suction. No prices were given for either pump, so check the current store prices on this page. If the two are close in price, the AQUASTRONG buys more flow; the Pearl buys published pressure and temperature ratings.

Can both run on 115 V or 230 V?

Yes. Both are dual voltage 115/230 V. The Pearl lists 21/10.5 A draw, so confirm your circuit and breaker size before wiring either one.

Neither maker publishes a service life. The AQUASTRONG has a cast iron body for outdoor duty; the Pearl's 56J motor frame makes the motor easier to replace if it fails.
