Theory of Operation

The Aqua Void Auto Bilge Pump is engineered with an enhanced cartridge motor featuring a w high-flow impeller, delivering powerful and efficient water removal capabilities. This innovative design introduces the industry's first quick-change motor connection, allowing for seamless cartridge motor replacements and capacity upgrades.

Central to its operation is the advanced auto-sensing motor cartridge, which utilizes resistance to detect the presence of water within the bilge. This auto-sensing technology eliminates the need for an external switch, significantly reducing the pump's overall footprint and simplifying installation.

The Aqua Void Auto is characterized by its uniform pump housing across all Aqua Void models, with the key differentiator being the integration of the auto-sensing motor cartridge. The pump operates through an automated cycle, where every 2.5 minutes, the impeller briefly spins for 1 second. This brief rotation is designed to sense the presence of water. If water is detected, the pump transitions into full operation mode, efficiently removing the water until the bilge is dry.

When no water is detected, the pump ceases its operation and repeats the sensing cycle at the next 2.5-minute interval. This automated process ensures continuous monitoring and efficient water management, providing reliable performance and making the Aqua Void Auto Bilge Pump an essential solution for automated bilge water management.
