Key Features to Look For
When shopping for a water pump, focus on these essential attributes that define SEAFLO's lineup:
- Flow Rate (GPM): Delivers 3.0-3.3 gallons per minute for quick filling of tanks or showers.
- Pressure (PSI): 45 PSI ensures strong, steady flow even with multiple outlets open.
- Self-Priming: Pulls water from up to 6-9 feet below, ideal for irregular water sources.
- Voltage Options: Choose between 12V DC for battery-powered setups or 110V AC for shore power.

Comparing SEAFLO 33 Series Models
Our category features two standout 33 Series pumps tailored to different power sources, helping you pick the perfect fit.
The 12V RV Water Pump (3.0 GPM, 45 PSI) is a diaphragm powerhouse for off-grid use. It's compact, runs quietly on RV batteries, and suits campers, boats, or marine fresh water systems. Perfect for self-priming in RVs where space and power efficiency matter most.
In contrast, the 110V AC Pressure Pump (3.3 GPM, 45 PSI) leverages standard household outlets for higher-capacity needs. With its smart pressure switch, it maintains consistent flow in caravans, marine applications, or industrial setups connected to shore power. Both share the same rugged build, but the AC model edges out in flow rate for larger demands.
Choose the 12V for portable, battery-dependent mobility or the AC version for stationary or plugged-in reliability. If you're comparing alternatives, check out Gates Water Pumps or ACDelco Water Pumps for traditional engine-focused options in our Replacement Parts lineup.
Common Use Cases
SEAFLO pumps shine in real-world scenarios:
- RV and Camping: On-demand water for sinks, showers, and appliances without constant running.
- Marine and Boats: Reliable fresh water circulation in tight bilge spaces.
- Caravans and Industrial: Steady pressure for workshops or remote sites.
Their corrosion-resistant materials and dry-run protection prevent failures, saving you from costly downtime.
