The Shurflo Blaster II is a 24 V DC washdown pump that runs on demand through a sealed switch. It has four independent chambers, and fittings plus a nozzle come with it. It is self-priming up to 6 feet, thermally protected and ignition protected, and it can run dry without damage.
Our take
The dry run capability means this Blaster II will not be damaged if the water supply runs out mid-wash, and it primes itself up to 6 feet. Ignition protection is listed too, so it is built for use aboard.
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.
