f4b-11 model 10-24690-01 to be specific. <BR> <BR>here's a url of the specs on the pump. <BR><a href="http://www.aquafax.co.uk/pdfs/Sect10J.pdf" target="_blank">http://www.aquafax.co.uk/pdfs/Sect10J.pdf</a> <BR>It's ignition proof. Anyone have experience with these pumps or this brand? I am setting up a ballast system and I think I may have a lead on some 1+ inch 12v actuated ball valves mad flow! :-D I already have a lead on some pretty awesome mega flow spring ball check valves if I go with aerator pumps for evacuation. <BR> <BR>They also make these monsters! 1600gph <BR><a href="http://www.boatfix.com/shop3/store/listItems.asp?strSearch=189-1600B" target="_blank">http://www.boatfix.com/shop3/store/listItems.asp?strSearch=189-1600B</a> <BR> <BR> <BR>I know jabsco is like the de facto but is it worth looking @ other suppliers? The reversible "ballast" pump above is 9-12gpm where the ballast puppy is like 10 and double the johnson's list price.

I looked at prices and the johnson pump discounted price without the switch is 194. Discounted price on the Jabsco is $205 to $220 which includes the switch. Priced about the same to me. The new Jabsco specs is 11gpm per there website.

I looked at the Johnson's, mostly because of the price difference from the Jabsco's. The big difference between the two is that the Jabsco ballast puppy has an automatic shutoff. <BR> <BR>Here's the issue with the Johnson pumps: <BR>You WILL leave your pumps running at least once... With the Johnson pumps, that will leave you with a burnt-up impeller, or worse, needing an entirely new pump. I'm sure there are ways of wiring a relay in to prevent this... but for me, it just makes sense to pay a little more and get the pump that is built specifically for our application. <BR> <BR>Hope that helps and good luck.

I'm not defending johnson or anything but the site says: <BR> <BR>"Capable of pumping fresh or <BR>sea water the pump’s robust design can handle the rigors of <BR>continues duty usage, is reversible, &amp; has a built in thermal overload <BR>for added protection" <BR> <BR>My biggest concern is if anyone will carry parts for the things. I will admit the site and branding looks very "offshore"

I just ordered tsunami pump. They are only $40.00 a piece and pump 1200gph.
