Question:

Hi, What is the difference between the Seaflo SE58FR and SE57FR? Do you sell and can you recommend a power supply for this pump 120V to 12V DC rated for at least 7.5 amps and suitable for damp or wet locations? Thank you

The difference between the two pumps is that the Seaflo Diaphragm Pump for Boats and RVs # SE58FR has a 3-chamber diaphragm for water flow up to 2 fixtures, while the Seaflo Diaphragm Pump for Boats and RVs # SE57FR has a 4-chamber diaphragm for water flow for up to 4 fixtures.

In regards to power supply, according to the manufacturer these each require their own dedicated circuit and are 12 volt only, with the red lead going to the positive terminal of your battery and black lead going to the negative terminal. They also need a switch, and should be fuse-protected. The # SE58FR requires a 20 amp fuse and the # SE57FR requiring a 10 amp fuse.
