Manuals

The Jabsco 50840-0024 is a 24V Cyclone centrifugal pump built for low pressure and high flow, with a stainless steel build. Its 3/4 in female NPT ports sit on a rotatable head. Jabsco rates the motor for 3500 hours of life and continuous duty, and the maximum pressure is 8.7 psi with the outflow blocked. As a centrifugal pump it should sit at the lowest fluid level so the suction port stays flooded.

Our take

The 3500 hour motor life and continuous-duty rating point to circulation work that runs for long stretches, such as hot water systems or livewell circulation. Being centrifugal, it needs mounting at the lowest fluid level so the suction port stays flooded.

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.
