Seaflo 33-Series
Score: 78/100Rankings
The Seaflo 33-Series is a compact, pre-assembled 12V DC pressure system designed for marine and RV applications, featuring a 3-chamber diaphragm pump with an integrated accumulator tank. It delivers smooth, consistent water flow but is limited by an intermittent duty cycle and high current draw. Best suited for marine fresh water systems and RV van conversions requiring compact, demand-operated pressure.
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.
