Seaflo 43-Series
Score: 88/100Rankings
The Seaflo 43 Series is a compact, self-priming 12V DC diaphragm pump designed for marine, RV, and off-grid water systems, delivering up to 3.0 GPM at 55 PSI. It features internal bypass technology and Variable Flow Technology to minimize cycling and noise while eliminating the need for an external accumulator tank. It is ideal for medium-duty, battery-powered water systems in RVs and boats requiring consistent pressure for multiple outlets.
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.
