- High Flow Rate with 5-Chamber Diaphragm Design: The SEAFLO 55-Series Diaphragm Pump is engineered with a 5-chamber diaphragm that delivers an impressive flow rate of 5.5 gallons per minute (GPM). This high-volume output ensures that you can supply water to up to six fixtures simultaneously, making it ideal for a wide range of applications, from washing to bathing. The advanced diaphragm design reduces pump cycling, providing a smoother and more consistent water flow. Whether you're using it for your RV, boat, or water purification system, this pump delivers the power and performance you need.
- Heavy-Duty Pressure Switch with Built-In Bypass: The SEAFLO 55-Series pump is equipped with a heavy-duty pressure switch that provides precise pressure control and stable performance. The built-in bypass function further enhances the pump's efficiency by reducing rapid cycling and allowing water to flow back from the outlet side to the inlet. This feature not only extends the life of the pump but also ensures that your water system operates smoothly and without interruption. The adjustable pressure setting allows you to customize the pressure to suit your specific needs, making it a versatile and user-friendly choice.
- Self-Priming with Robust Suction Power: Enjoy the convenience of self-priming with the SEAFLO 55-Series pump, which can achieve a suction lift of up to 9 feet. This powerful suction capability ensures that the pump can be mounted remotely from the water source, providing flexibility in installation options. The pump is also capable of running dry without damage, offering peace of mind in case of accidental dry operation. Whether you're drawing water from a tank, well, or other sources, this pump provides reliable performance every time.
- Quiet and Efficient Operation: Designed for quiet operation, the SEAFLO 55-Series pump runs at a noise level comparable to that of a ceiling fan. This makes it an excellent choice for environments where noise reduction is essential, such as RVs, boats, and off-grid cabins. The pump's semi-rigid rubber base minimizes vibrations, further reducing noise and preventing disturbances. Enjoy a peaceful and comfortable experience while the pump delivers high-power water flow without the constant hum of a noisy motor.
- Durable and Corrosion-Resistant Construction: Built to withstand the harsh conditions of marine and RV environments, the SEAFLO 55-Series pump features durable materials such as Santoprene for the diaphragm and EPDM for the valves. These materials are known for their abrasion and corrosion resistance, ensuring that the pump can handle both saltwater and freshwater applications without degrading over time. The pump's robust construction ensures long-lasting reliability, even in the most demanding conditions.
- Automatic On/Off Operation with Smart Pressure Switch: The SEAFLO 55-Series pump is designed for automatic operation, starting and stopping the pump when you open or close a faucet. This intelligent design provides an experience similar to using water at home, with water available whenever you need it without any manual intervention. The smart pressure switch ensures sufficient pressure and flow, making it easy to carry out daily activities such as washing, bathing, or cleaning. The adjustable pressure setting allows you to customize the pressure to suit your specific needs, providing convenience and flexibility.
- Versatile Applications for RVs, Boats, and More: The SEAFLO 55-Series Diaphragm Pump is a versatile solution for various water system applications, including RVs, boats, yachts, water purification systems, and other liquid transfer tasks. Its high flow rate, robust suction power, and durable construction make it suitable for both freshwater and saltwater environments. Whether you're using it as a washdown pump, potable water system pump, or shower drain pump, the SEAFLO 55-Series delivers consistent and reliable performance across a wide range of applications.

## Questions & Answers

**Q: Is 60 psi a Switch adjustable???**
A: No. 40 on, 60 off.  Actually some more like 65.  You can bypass pressure switch and put a square D switch on pressure side and set it wherever you want.

**Q: Does it come with the battery clamps and wiring harnesss?**
A: Negative. But I wouldn't recommend this product.
I had it on a boat water system and the pressure switch failed after a few hours of operation over a few weeks.  Put a new switch in and it failed again. Good pump, bad switch system.

**Q: Can I use it to pump saltwater**
A: I don't believe it is rated for salt water ... but for a short term I think it would work fine

**Q: I would like to use for a live well, is it self priming, water resistance or sealed, and how many amps?**
A: No this 12volt pump is not water resistant and is only capable of 5.5gph not 10. These are not designed to be exposed to elements. If you dont protect it and place in dry area away from elements it will fail and short out.17amps at start and about 7-8amps once running.It is self priming per specs to a point.All information you have asked is stated on amazon page and can be read faster there then asking this question to buyers/sellers.
