Questions & Answers

Is this a genuine original part?

This is a genuine Seaflo 33 Series pump, manufactured to meet global ISO 9001:2008 and RoHS standards.

How do I know if it is compatible?

If your current pump uses 1/2" NPT fittings and runs on a 12V system with a flow rate between 2.5 and 3.0 GPM, this is a direct replacement. Check the mounting pattern (3.25" x 4.75") for exact fitment.

Can the pressure switch be adjusted?

Yes, the 33 Series features an adjustable pressure switch located on the pump head, allowing you to fine-tune the shut-off pressure to your specific system requirements.

Note: Please ensure your battery can handle the 5.61A maximum draw and use a minimum 16 AWG wire for installation. For best performance, use the provided strainer to prevent debris from entering the diaphragm.
