When water starts rising in a bilge, you need the right 12-volt pump to get it out. But before you buy, know that the SEAFLO 01 Series and the TruePower utility pump are built for different jobs. SEAFLO is a high-volume submersible bilge pump; TruePower is a lower-flow utility transfer pump. The decision comes down to how much water you need to move and how fast.
Quick Verdict
Pick the SEAFLO when you want maximum pumping speed through a large outlet, and pick the TruePower when you want a smaller-flow utility pump for transfer work and lighter bilge duty. The TruePower costs $54.99, while the SEAFLO costs $99.99.
At a Glance
| Pump | Price | Relative Price | Flow Rate | Connections | Max Head |
|---|---|---|---|---|---|
| SEAFLO 01 Series 4700 GPH Bilge Pump | $99.99 | 4700 GPH | 2" outlet | 26.2 ft | |

Where Each Pump Wins
SEAFLO 01 Series 4700 GPH Bilge Pump: This is the pump for high-volume water removal. Its large outlet and strong head move water fast and push it well above the waterline.
TruePower 12V DC Utility Transfer Pump: This is the pump for transfer work. The stainless steel housing and standard NPT fittings make it easy to connect to hoses and tanks, and the 5-amp draw is lighter on your electrical system.
Detailed Look
SEAFLO 01 Series 4700 GPH Bilge Pump
SEAFLO's 01 Series is the pump you turn to when a bilge fills fast and you need water gone now. It moves 4700 gallons per hour, works through a 2-inch outlet, and reaches a maximum head of 26.2 feet, so it can push water up and out of a deep bilge. The anti-airlock protection helps clear trapped air during priming, and the snap-off strainer base makes debris cleanup easier. At 4.4 pounds, its ABS housing keeps weight reasonable for a pump this size. The trade-off is electrical demand: it draws 17 amps, with a max draw of 32.1 amps, meaning your wiring and battery need to handle that load. The 4-year limited warranty and CE/RoHS certification back the package. Choose it for high-volume marine water removal, not for low-flow transfer work.
TruePower 12V DC Utility Transfer Pump 240 GPH
The TruePower takes a different approach: it is a stainless steel pump that flows 240 gallons per hour and can lift water 23 feet. With a maximum pressure of 50 PSI, it performs better when moving water through hoses and lines rather than trying to keep up with a flooded bilge. Its 3/8-inch NPT female inlet and 3/4-inch NPT male outlet let you connect to standard plumbing fittings, which helps with transfer jobs such as draining tanks, moving water in an RV, or emergency water removal. Amp draw is only 5 amps at 120 watts, so it is easier on a small battery. The package includes an extra impeller for future maintenance. The limitation is volume: 240 gallons per hour is far below the SEAFLO's flow, so a full bilge will take much longer to clear. For lighter duties, it is the more practical option.
Final Choice by Use Case
If your main worry is a boat bilge that can fill quickly, choose the SEAFLO bilge pump and its high-volume water removal. If you need one pump for utility transfer, RV/camper water movement, smaller bilge jobs, and tasks where portability and low power draw matter more than raw flow, choose the TruePower utility transfer pump.
