Irrigation pump ideas

This is a hail mary shot in the dark but here goes. I currently have a 10hp berkely pump with a 7.875 impeller diameter.  Model B1.5ZPL. I have four screens the water must pass through to get to my foot valve. Small screens. As in 1/16" small holes or so. I pump out of a really dirty canal. Despite my screen setup my pump gets clogged after just a few hours of use from grass and crap from the canal. The impellers get jam packed clogged up. I have a 5' inline filter just past the pump which also catches stuff but the freaking pump itself gets clogged so it is a daily chore to go down to the pump and pull the bolts and motor off and clean the impeller out and put it all back together. It takes an hour every time and I am absolutely out of ideas. A neighbor has a 30hp pump just several feet from mine without a single filter and his has never once gotton clogged up. My brother in law a few hundred yards down the canal uses a 5hp pump without a single filter and has never once had his impellers get clogged up. My sister in law a mile down the canal uses a 3hp or so pump and pumping out of the same canal with no filter has never once had their impellers clog up. My father in law pumps out of the river a mile from me with zero screens except for a huge one to keep out sticks and he has never had the impellers clog up on his pumps. Last week I called Berkeley and talked with a trouble shooting representative about my pump model and I asked him if they knew of this particular model  having a susceptability (spelling) to getting clogged up in the impellers and I described to him what was happening with it but he had no clue. I didnt know if the design, shape, and size of the impeller in this model made it more suspetible to gathering crap and clogging up for whatever reason but he hadnt heard of anything and had zero ideas. By the way this pump is about 4 years old and it has always been a pain with clogging up but this summer is by far the worst ever. I am already watching craigslist/auctions for a bigger pump. Id like to put in a 15 hp or even a 20 hp even though I dont need one that big but hopefully the bigger impeller will help. Any ideas would be appreciated!

I wish that were the case but in this instance it is not. I used to not have a screen. But I had this problem of it getting clogged up without a filter/screen. So I put in a screen, then a second, third, and fourth, but the problem persists. The screens stop alot of the crap in the water from even getting to the intake pipe but apparently not all of it. Also the water level only drops a couple inches  from the ditch to the intake pipe when it is pumping, but there is still  30" from the top of the water to the bottom of the foot valve. The closest screen is about 12" away and the furthest screen is around 4' to 5' away with the other two screens in between. So hence why I am saying WTH.

If you have 4 suction screens and the pump impeller is getting plugged... you got the wrong design pump/ impeller for the job...... Buy one like your buddy has.

I looked up that pump with the impeller you listed... Pump will put out 92 GPM at 110 psi...... What are you doing with the water ?  Do you need 110 PSI ?  Are the buddiess pumps putting out that kind of pressure ?   You may want a LOW PRESSURE, HIGH FLOW pump with a bigger more open impeller ??  Again, i would examine THEIR pumps a little closer..

I think you need to switch places with one of them down the line!
