Questions & Answers
Is this a genuine original part?
This is a genuine Seaflo 41-Series product. Seaflo is a world-leading manufacturer of marine and RV fluid handling equipment, known for high quality and reliability.
How do I know if it is compatible?
If your current pump provides roughly 3 GPM and operates on 12V DC, this is a perfect upgrade or replacement. It uses an industry-standard mounting pattern, making it a drop-in fit for most Jabsco and Shurflo setups.
Do I need an accumulator tank with this pump?
No, an accumulator tank is not strictly necessary. The 41-Series features a built-in internal bypass that significantly reduces pump cycling (on/off hunting) when using low flow rates, providing a smoother water stream.
