Score: 88/100
SEAFLO Marine Water Pump
Score: 85/100Rankings
The Rule 14A is a heavy-duty, non-automatic submersible bilge pump designed for high-volume water evacuation on larger vessels. Its key strength is its robust construction and high flow capacity, making it an industry workhorse. However, it lacks automatic sensing, requiring users to install and maintain external switching systems.
The Seaflo 55-Series 5.5 GPM marine water pump is a heavy-duty, self-priming diaphragm pump designed for high-volume applications in marine, RV, and off-grid settings. It delivers 60 PSI of pressure with a flow rate of 5.5 GPM, supporting up to five simultaneous outlets without requiring an accumulator tank, though one is available for reduced cycling. While it offers excellent performance and durability, the high amperage draw requires careful electrical planning.
