How many gph?Greets all I'm new here hope to contribute as best I can, have had many successful crops though so I'm not quite a newbie. Question for you hydro/aeroponics folks:
Anyone ever run into an issue where water pump impeller vanes keep breaking? They all seem to be made the same, crappy plastic impeller with 5 or so vanes on it. Mind you I don't expect my pumps to last forever, but none of them seem to last a full year. Never ran dry, 3 separate pumps to ensure not overloaded, also to not have all eggs in one basket so that only a few plants would be affected at a time if one failed. They are on a timer that runs every 5 mins for 45ish seconds. They still work when this happens but obviously with reduced pressure and not ideal. The brand is Active Aqua but I've searched and searched, they all seem to be built mostly the same (at least for mag drive pumps) with the same plastic impeller.
Wouldn't they be better with a stainless/aluminum impeller, or something less fragile but still not corrosive? Anyone know of a different style pump, or different make that are built better?
Cheers
If that is regular plastic, it won't last long. If it's nylon, it will outlast the pump.The plastic tabs themselves, no problems with the rest of the impeller shaft/magnet. My local hydro shop doesn't have the replacement impellers/magnets so instead of waiting for shipping I always just buy a brand new pump (sometimes they'll warranty them for me).
Here's a picture of the one that just happened.
Good idea, thought of this but to get it done in metal instead (some sites online will fabricate items if you send them the design). Can nylon be 3D printed easily?If that is regular plastic, it won't last long. If it's nylon, it will outlast the pump.
Have a friend with a 3D printer? Make one that will last.
I used to take advantage of stuff like this. 45G drum on main floor and 30 or so tanks I the basement that's why its funny to my. Not very feasible and a space hog and eye sore. But it beats lugging water.Replace your pumps with a mini version of this and never need another one.
This is so simple, and it's vacuum/gravity powered.
I have some aero nozzles but I worry about burning up pumps with plastic pumps. Wonder if there's a good pump with a metal impeller for cheap somwhere. I would think most plastic impeller pumps are not made for high pressure aero. I'm sure a rock would help but it seems like they would break regardless unless they are good quality. Pretty much the only reason I havnt done some aero yet is fear of burning up the pump.Imo try to find a rubber impeller. But yeah only way those are breaking is like gravel or something.
Well it might not be aero, I am just assuming because he said hydro/aeroponics and then talked about pressure drop. I have no idea how aero works but his is on a timer too.Oh geez I didn't see it was aero... wow I'm slow.... small diaohram pump works well.
Now off to my hooked on phonics lesson.
