Hi all, a friend of mine is looking for ideas about the best low surge well pump.
Something with soft start it would seem.
I am far from knowledgeable on this topic.
What well pump are you using? Are you using solar?
He's got a good inverter. But he's looking to downsize it (and that 40w/hr idle draw!) and the drawback is that to do so he has to replace his well pump.
Ideas?
He's hoping for cheap.

Grundfos has some 2 wire 115v 1/2 HP pumps that I've seen others use from inverters adn small generators. IIRC, the 5 GPM SQ pump uses 4-5 Amps running, and I think a startup MAX Of 12 Amps. I THINK.
Grundfos has a whole line of pumps now for renewables, too. SQE, I think.

I second the Grundfos pump. I and a neighbor rancher friend have their SQFlex series pumps running off solar panels, some with batteries some without. They have both helical gear pumps for depth and centrifugal for higher flow.

Rockies - great link for the water pumps. I have two manual ones that I am thinking of converting and have a small solar set up as well as a good-size generator. I like the idea of being able to fill my loft tank for the bathroom water supply with a small electric pump instead of the Guzzler pump currently used. It takes about 180 pumps to fill it (35gals) and I am not getting any younger. I was looking at jet pumps but after reading the article, I would likely go with a piston type pump.
