Replaces 504156 - Rule 25S 500 Automatic Submersible Bilge Pump

The Jabsco Rule 25SA 500 series automatic submersible bilge pump with 750mm cable eliminates the need for a separate float switch to activate the pump. Once power is supplied to the bilge pump, starting and stopping is completely automatic.

The Rule automatic bilge pump turns on and checks for water every 2 1/2 minutes, during this check the pump runs for approximately 1/2 a second and checks for resistance or drag against the impeller. If resistance is encountered, it will run until water is no longer present. Thereafter the automatic bilge pump resumes the 2 1/2 minute check cycle. The automatic bilge pump can be started at any time by turning the power off; waiting 5 seconds and then turning the power back on. The pump will start immediately and pump until the water is removed.

The Rule automatic submersible bilge pump is a light weight, compact pump with a tough plastic body and integral strainer. The automatic bilge pump features two leads, an automatic (brown) and a manual override (brown with a white stripe). The quick release strainer allows for rapid cleaning of the submersible bilge pump internal components.

The Rule 500 series of small submersible bilge pumps are recommended for discharge heads up to a maximum of 2 metres. The submersible bilge pump meets ISO8846 marine (ignition) and ISO8849 marine (bilge pump) standards.

The power use during the checking mode is minimal, the bilge pump will consume 0.20 amp hours per day in the checking mode.

Please note - Output is based on 10 hour break-in period and at 13.6V, a minimum voltage of 10.5V is required.

The Rule 25SA replaces the 12 volt Rule 25S and has the following features:

  • Higher Flow - through an optimised impeller, the 25SA is able to provide greater flow at the same amperage
  • Built-in Thermal Cut-Off (TCO) - this provides extra protection for both the pump and the vessel it is installed in
  • Back Flow Prevention - the check valve reduces the amount of water left in the bilge, minimising odour and helping to keep your bilge cleaner
  • Hidden Air Vents in the Body - these vents help prevent air-locking in challenging plumbing installations and helps with the check valve
  • Threaded Discharge Ports - this allows for easier pump installation, and easier maintenance
  • No need for a separate float switch, as there is a third wire for a manual override.
  • Base Fits Existing Rule 25S Screw Holes

Flow Rates:

  • Open flow output at 0m/0ft (0 kPa): Up to 31.5 LPM (8 US GM)
  • Open flow output at 1m/3.35ft (10 kPa): Up to 22.7 LPM (6 US GPM)
  • Open flow output at 2m/6.7ft (20 kPa): Up to 16.4 LPM (4 US GPM)
