Seaflo 24V Water Pressure Pump
41 Series | 3.3 GPM | SFDP2-033-035-41
The Seaflo 41-Series is a heavy-duty, on-demand positive displacement diaphragm pump designed for high-volume water flow. Engineered for 24V DC systems, it delivers a smooth 12.5 Litres Per Minute (3.3 GPM) flow rate, making it capable of supplying up to three fixtures simultaneously.
Equipped with a quad-chamber diaphragm and an internal bypass, this pump significantly reduces "cycling"—the rapid turning on and off of the motor—eliminating the strict need for an accumulator tank. It is self-priming and safe to run dry without damage, ensuring reliability in demanding marine, RV, or agricultural environments.
Key Features
- ✔ Self-Priming: Suction lift up to 6 feet (1.8m)
- ✔ Run Dry Safe: Won't damage the motor if water runs out
- ✔ On-Demand: Integrated pressure switch for auto start/stop
- ✔ Low Power: Designed for efficient 24V DC draw
- ✔ Silent Mounts: Rubber feet for noise reduction

Questions & Answers
Is this a genuine Seaflo part?
Yes, this is an authentic Seaflo 41-Series product, supplied brand new in original packaging for 4boats.co.uk customers.
Do I need an accumulator tank with this pump?
Generally, no. The internal bypass design handles various flow demands and prevents rapid motor cycling, though an accumulator can still be used to further reduce noise and wear.
Can this be used with salt water?
Yes, the materials used (EPDM and Santoprene) are compatible with both fresh and salt water applications.
Note: Please verify your original part number and system voltage (24V DC) against the references above before purchasing. This is a 24V pump and will not operate correctly on 12V systems.
