SEAFLO Marine Water Pump
Score: 85/100Rankings
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.
The Jabsco PAR-Max 1.9 is a compact, low-noise freshwater pressure pump designed for marine and RV on-demand water systems. Its main trade-off is the intermittent duty cycle and lower pressure output, which limits its use to basic fixtures. It is best suited for boats with up to three water fixtures where quiet operation and battery efficiency are priorities.
