- ✔️ [ HIGH FLOW RATE WITH 5-CHAMBER DESIGN ] : The advanced 5-chamber diaphragm ensures a high flow rate of 5.5 GPM, making it capable of supplying water to up to six fixtures at once. This design not only supports various simultaneous water uses—like showering, washing, or dishwashing—but also reduces pump cycling, delivering consistent water pressure. Whether used for marine, RV, or off-grid systems, this pump ensures dependable and continuous water flow.
- ✔️ [ HEAVY-DUTY PRESSURE SWITCH WITH BUILT-IN BYPASS ]: The upgraded pressure switch offers precise pressure control and stable performance by automatically activating the pump when needed and stopping it once the desired pressure is reached. The built-in bypass mechanism minimizes rapid cycling by maintaining consistent pressure, allowing water to flow back from the outlet side to the inlet if necessary. This function extends the pump’s lifespan and ensures a seamless water supply, making it particularly beneficial for systems with multiple water outlets.
- ✔️ [ SMART PRESSURE SWITCH WITH LONG LIFETIME ]: The SEAFLO 55-Series features a reliable Smart Pressure Switch that activates the pump automatically when water is needed and stops it when the demand ceases. Built for endurance, it offers a lifetime of over 200,000 on/off cycles, ensuring consistent and long-lasting performance for various water systems. This non-adjustable switch provides optimal pressure control without manual adjustments.
- ✔️ [ SELF-PRIMING & RUN DRY CAPABILITY ]: This pump’s self-priming feature allows for a powerful suction lift of up to 9 feet, making it versatile for remote installations. This means the pump can be positioned above the water source, offering greater flexibility in setup without compromising performance. Additionally, the pump can run dry without damage, protecting the internal components during low-water conditions or accidental dry operation, making it a reliable solution for various water transfer tasks.
- ✔️ [ QUIET & EFFICIENT OPERATION WITH NOISE REDUCTION ]: Engineered for quiet operation, the SEAFLO 55-Series pump functions at a noise level comparable to a ceiling fan (65 dB). The semi-rigid rubber mounting base reduces vibrations, significantly lowering noise levels and ensuring a peaceful environment. This makes it particularly suitable for indoor use, such as in RVs or boats, where minimal noise is preferred.
- ✔️ [ DURABLE & CORROSION-RESISTANT MATERIALS ]: Built to withstand harsh marine and RV environments, the pump uses premium Santoprene for the diaphragm and EPDM for the valves. These materials offer excellent abrasion and corrosion resistance, making the pump suitable for both freshwater and saltwater applications. Its construction ensures durability and long-lasting reliability, even in high-moisture or corrosive conditions.
- ✔️ [ VERSATILE APPLICATIONS FOR RVs, BOATS, AND OFF-GRID SYSTEMS ]: The SEAFLO 55-Series pump is designed to cater to diverse applications, including washdown systems, potable water supply, shower drains, and water purification systems. Its robust performance makes it a perfect fit for RVs, boats, yachts, and off-grid cabins. With its ability to handle both freshwater and saltwater, it serves as a versatile solution for various liquid transfer needs
- ✔️ [ EFFICIENT HEAT DISSIPATION & LOW STARTING PRESSURE ]: The heavy-duty pressure switch is designed with efficient heat dissipation capabilities, ensuring that the pump can run continuously without overheating. It is also engineered to work with a low starting pressure, preventing unnecessary pump cycling and reducing wear and tear on the motor.
SEAFLO 12V Water Pressure Diaphragm Pump 5.5 GPM (20.8 LPM) 60 PSI

The 55-Series is our all new heavy duty water pressure pump with the most heavy duty pressure switch on the market. It provides high volume water flow with reduced pump cycling and smooth flow thanks to the large five-chamber diaphragm. It provides up to 5.5 gallons per minute. The 55-Series pumps are self-priming, can run dry without damage, and are performance reliable. This automatic demand water system pump has a built-in pressure switch which automatically starts and stops the pump when the faucet is opened and closed. Easy to install service and winterize. This pump works best when paired with a SEAFLO Accumulator Tank.
