Are these the same pump?

Yes. The AQUASTRONG listing gives the model as SPRK150, which is the Red Lion part number, and every core spec matches: 1.5 HP, cast iron, 2" suction, 1-1/2" discharge, 115/230V. Buy on price and return policy.

Which moves more water?

Effectively the same. Red Lion rates 71 GPM, about 4,260 GPH; AQUASTRONG rates 4,250 GPH. That is a rounding difference, not a real gap.

Which is better for a pond-fed sprinkler system?

Either. Both self-prime from a pond or lake and push to about 44 to 47 PSI, enough for a zone of standard 4 GPH heads. Keep the suction line short and use a foot valve.

Is the AQUASTRONG worth the extra money?

Only if it is not actually extra. Since it is the same pump, pay less unless the pricier seller offers a better warranty or easier returns.

How many sprinkler heads can one run?

Red Lion says 17 heads at 4 GPH each. That assumes short pipe runs and matched heads; long runs or big rotors will cut the count.

Will either survive winter?

Neither is freeze-proof. Drain the pump and suction line before the first hard freeze or the cast iron volute can crack.
