Rule 500 GPH Bilge Pump (31 L/min) 12V


Rule’s compact submersible 500 GPH electric pump is designed for use as a bilge or bait pump on smaller crafts.

This pump features a water cooled, ignition and TCO protected motor, stainless steel shaft and snap-on strainer base.

It’s extremely efficient, offering low current draw and high-capacity output in a very compact housing to fit into the smallest available space.

This pump requires a Rule float switch to operate automatically (sold separately – see related products). Using the included check valve will reduce the output flow of the pump.

Product Features:

  • Fully submersible pump – 500 US gallons per hour – 31 litres per minute
  • Higher flow – optimised impeller to provide greater flow at the same amperage as previous model.
  • High efficiency, low amp draw, ignition protected motor includes true Electromagnetic suppression (EMC)
  • 16-gauge tin coated copper electrical wiring with silicone infused water blocking feature – to stop water wicking down inside the wiring
  • In-built thermal cut-out (TCO) in the motor provides additonal protection for pump & vessel.
  • Backflow prevention – now includes a removable check valve in the discharge nozzle which reduces the amount of water draining back from the pump discharge hose into the bilge.
  • Please note – using the check valve will reduce the rated output flow.
  • Threaded discharge port – gives easier installation and maintenance.
  • Discharge hose port is included with each pump.
  • Hidden air vents in the pump prevent air locking in challenging plumbing installations and helps with the check valve operation.
  • Compact – 99mm Height x 74mm Width x 64mm depth – not including discharge.
  • 1.6 amp draw @ 12v DC
