The Par-Max HD4 is a Jabsco freshwater delivery pump, in the 12V DC, 60 PSI version rated at 4 GPM. A sealed pressure switch built into the pump runs it on demand. It primes itself, tolerates running dry, and has quick connect ports and vibration dampening mounting feet. An integrated bypass module cuts cycling for smoother flow.
Our take
The HD4 can run dry without damage, so a tank that empties underway shouldn't ruin the pump, and it primes itself, which gives you more choice on where to mount it. The bypass module cuts cycling and gives a steadier flow at 60 PSI.
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.
