Rule PWC 500 GPH Automatic Sensing Bilge Pump

Description

The Rule PWC 500 GPH Automatic Sensing Bilge Pump provides automatic bilge-water removal using electronic sensing instead of a separate mechanical float switch. The pump briefly cycles at regular intervals and monitors impeller resistance; when water is detected, it continues running until the bilge is cleared and then returns to its monitoring cycle.

This sensing approach keeps the automatic control inside the pump package and eliminates an external float arm that can be obstructed by loose debris. Submersible construction, marine-oriented wiring, and Rule’s compact pump design make the unit suitable for compatible bilge installations where automatic operation and straightforward service are priorities.

Confirm the boat’s electrical system, circuit protection, discharge-hose routing, mounting position, and access for cleaning before installation. Keep the intake free of debris, secure wiring above normal bilge water where practical, and test several sensing cycles with water present before relying on unattended operation.

• Impeller-resistance sensing provides automatic control inside the pump assembly.
• The control system resumes periodic checks after detected water is removed.
• Electronic sensing avoids a conventional external float mechanism.
• Pump and automatic control occupy one integrated package.
