The Jabsco Par-Max HD5 is a 12V DC freshwater delivery pump rated at 5 GPM and 60 PSI. A sealed pressure switch lets it run on demand, and it is self-priming. The HD build has a heavier motor and a cast aluminum lower housing. It has both 1/2 inch and 3/4 inch hosebarb ports, can run dry without damage, has an integrated bypass module to cut cycling, and draws up to 13.0 amps.
Our take
With a 13.0 amp maximum draw on 12V DC, the HD5 needs wiring and a fuse sized for a serious load. Its heavy duty motor and cast aluminum lower housing go with the 60 PSI rating, and it can run dry without damage.
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.
