This is the Shurflo Blaster II washdown pump in its 12V version with a pistol grip nozzle. Fittings and the nozzle come with it. It is an automatic demand pump with a corrosion resistant electro coated motor. Four independent chambers do the pumping, with a built-in check valve. It is thermally protected, can run dry without damage, and is self-priming up to 6 feet.
Our take
A washdown pump that can run dry without damage and is thermally protected is hard to hurt if the water supply is interrupted. With self-priming up to 6 feet, the Blaster II can also draw from a source below it.
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.
