Description

Rule 56S 4000 Automatic submersible bilge pump with a flow rate of up to 252 LPM (66 GPM).

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 second and checks for resistance or drag against the impeller. If resistance is encountered, it will run until water is no longer present.

The Rule submersible bilge pump is a light weight, compact pump with a tough plastic body and integral strainer. The quick release strainer allows for rapid cleaning of the submersible bilge pump internal components.

The Rule 4000 range of small submersible bilge pumps are recommended for discharge heads up to a maximum of 4 metres. The submersible bilge pump meets ISO8846 marine (ignition) and ISO8849 marine (bilge pump) standards.
