RV Diaphragm Water Pump 3.3–5.5 GPM | SucceBuy Boat Sprayer
SucceBuy RV Diaphragm Water Pump — 3.3 / 3.5 / 5.5 GPM Adjustable Pressure
Keep water flowing wherever you go with the SucceBuy RV Water Pressure Diaphragm Pump. Available in three powerful configurations — 3.3 GPM / 45 PSI (110V), 3.5 GPM / 55 PSI (12V), and 5.5 GPM / 70 PSI (12V) — this self-priming diaphragm pump is engineered for campers, marine vessels, boats, lawn irrigation, agricultural spraying, and car washing. Made in Mainland China.
Why Choose This Diaphragm Pump?
- Three Powerful Configurations: Select the flow rate and voltage that match your exact application — 3.3 GPM at 110V for home-style RV setups, or 3.5/5.5 GPM at 12V for mobile off-grid systems.
- Smart Automatic Pressure Control: The built-in automatic pressure switch turns the pump on and off as you open and close the faucet. Pressure is fully adjustable — 40–80 PSI on the 3.3 & 3.5 GPM models, and 40–100 PSI on the 5.5 GPM model — with default settings of 45, 55, and 70 PSI respectively.
- Self-Priming Up to 6 Feet: The pump pulls water from sources up to 6 ft (1.8 m) below the unit, making installation flexible and convenient on boats, RVs, and tanks.
- Versatile Multi-Use Design: Ideal for RVs, campers, marine boats, lawn and garden irrigation, agricultural spraying, and vehicle washing — one pump for virtually every water-transfer task.
- Quiet, Energy-Efficient Operation: Engineered to run smoothly with minimal noise, so you can enjoy your outdoor adventures without disruptive pump noise or high energy consumption.
- Certified Safety & Durability: CE and FCC certified. Santoprene diaphragm material and EPDM valve material resist wear and corrosion. The reinforced PA6 + 30% Glass Fiber shell withstands demanding conditions. Includes sealing tape and overload protection for long-lasting, dependable service.
- Handles Solids Up to 300 µm: Capable of pumping liquids containing fine particles up to 300 µm (50 mesh), suitable for fertilizer solutions and lightly laden water.

Frequently Asked Questions
Q: What is the difference between the 3.3 GPM 110V and the 12V diaphragm pump models?
A: The 3.3 GPM model operates on 110V AC power, making it ideal for RVs with shore power hookups or standard household outlets. The 3.5 GPM and 5.5 GPM models run on 12V DC power, drawing directly from a vehicle or boat battery — perfect for fully off-grid campers, marine vessels, and mobile setups.
Q: Can I adjust the output pressure on these diaphragm pumps?
A: Yes. All three models feature an adjustable pressure range. The 3.3 GPM and 3.5 GPM pumps adjust between 40–80 PSI, while the high-flow 5.5 GPM model adjusts between 40–100 PSI. Each pump ships with a factory-preset default pressure (45, 55, or 70 PSI respectively) that can be fine-tuned to your application.
Q: Is this pump truly self-priming, and how high can it draw water?
A: Yes — all three models are self-priming and can draw water from a source up to 6 feet (1.8 m) below the pump inlet. No manual priming is required; simply connect the inlet hose and power on the unit.
Q: What connection size do these pumps use?
A: All models feature a 1/2" Male NPT (MNPT) inlet and outlet, a standard fitting compatible with most RV, marine, irrigation, and garden hose plumbing systems. Sealing tape is included to ensure a leak-free connection.
Q: Are these pumps safe for use with fertilizers or agricultural spraying solutions?
A: Yes. The Santoprene diaphragm and EPDM valve materials are chemically resistant and compatible with many water-based agricultural solutions. The pump can also handle liquids containing fine particles up to 300 µm (50 mesh), making it suitable for fertilizer or light-slurry applications. Always verify chemical compatibility with the specific solution you intend to pump.
