The Seaflo 51 NEW Series is a premium, heavy-duty on-demand water pressure pump designed for high-volume flow and durability. Featuring a sophisticated 5-chamber diaphragm, this pump provides smooth, consistent water flow to up to four fixtures simultaneously.

Is this a genuine original part?

This is a premium SEAFLO 51 NEW Series product, manufactured to the highest standards. 4Boats is an authorized distributor of Seaflo aftermarket equipment.

Does this pump require an accumulator tank?

While an accumulator tank is always beneficial for very fine flow control, the 51 Series features an internal bypass that manages pressure fluctuations internally, meaning it can be used effectively without one.

Can it be used with salt water?

Yes, the materials used (EPDM/Santoprene) and the waterproof/dustproof sealing make it suitable for both fresh and salt water applications.
