Rule 360 GPH 12V bilge pump marine electronic

SKU CH-CTH0-WHZ9K

A 360 GPH bilge pump that delivers full flow at 12 V instead of 13.6 V, with a hidden air vent to prevent airlocks, built-in thermal protection, electromagnetic suppression and a stainless-steel shaft

  • Delivers 360 GPH at 12 V for faster dewatering
  • Hidden air vent prevents airlocks during operation
  • Built-in thermal protection safeguards pump and vessel
  • Stainless-steel shaft resists corrosion in marine use
  • Integrated backflow preventer stops reverse water flow

What this pump does

The Rule 360 GPH 12V bilge pump is a non-automatic submersible unit designed to remove water from a boat bilge using a panel switch or separate float switch. It delivers 360 GPH at 12V rather than the 13.6V previously required, matching typical onboard voltage supply.

Voltage and flow reality

The pump produces its rated flow at 12V, which is more typical of actual onboard voltage than the 13.6V needed by earlier designs. It is ignition protected and includes a built-in thermal cell that protects the pump and vessel if temperatures rise too high.

Build details for daily use

A stainless-steel shaft and true electromagnetic suppression (EMC) increase durability in the marine environment. An included backflow preventer and hidden air vents under each strainer tab stop airlocking, while the non-automatic design means you must add a switch for operation.

Questions about this item

Should I choose the 360 GPH model or a higher-capacity pump for my bilge?

The 360 GPH rating suits small to medium bilges needing moderate water removal.

What does the 360 GPH figure mean when the pump runs on my boat's 12V system?

It delivers the rated flow at 12V, matching typical onboard voltage instead of the 13.6V previously required.

How does the 12V connection affect installation and circuit protection?

The pump connects directly to a 12V supply via a panel or float switch and includes built-in thermal protection for the motor and vessel.
