The Shurflo Aqua King II Supreme is a 24 volt demand water pump rated at 5.0 GPM and 55 PSI, built for boats with several fixtures. A mechanical bypass lets it vary its flow with demand. It self-primes to 6 ft and can run dry without damage. An inlet strainer and 1/2 inch hose barb fittings come with it. The duty rating is intermittent, as with demand pumps in general.
Our take
Self-priming to 6 ft and tolerance for running dry mean an empty tank will not damage the pump itself. The catch is the intermittent duty rating, so treat it as a demand pump for fixtures, not something to run continuously.
From our buying guide
Size a freshwater pump by the outlets that must run at once. Jabsco's rule of thumb is 1 GPM per outlet, and the listed flow is open flow, which falls as pressure rises.
Check before you buy:
- The data sheet shows flow at pressure. One Shurflo gives 4.0 GPM at 0 psi and 2.0 GPM at 40 psi.
- You have an inlet strainer, which Jabsco says is required in every freshwater pump installation.
- An accumulator suits the pump. Jabsco says one cuts cycling on a pressure-switch system, and not to use its accumulators with variable-speed pumps.
