This is the Jabsco Par-Max 1.9 GPM water pressure pump, a 12 volt DC unit meant for a quiet, smooth, on-demand supply. It cuts off at 25 psi (1.7 bar) and has a built-in bypass to reduce pulsation, which the maker says lessens the need for an accumulator tank. It can run dry, sits on soft noise absorbing mounts, and is listed to ISO 8846 for ignition protection.
Our take
The built-in bypass is what cuts pulsation here, and the maker says it lessens the need for an accumulator tank. Add dry running capability and soft noise absorbing mounts, and this is a pump set up for quiet, forgiving service with a 25 psi (1.7 bar) cutoff.
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.
