Whoops. Yes, typo on the flow rate. I meant to say 40GPM. Gallons per minute. So with a 4" sleeve I shouldn't see any reduction in rated flow?

Hey all, I'm going to be installing a 35S20-8 SP pump and I'm trying to figure out what the appropriate flow inducer sleeve size would be. I see most threads on here people using a thin wall 4" PVC for a 4" pump, but I've also seen some mention of friction loss and larger sleeves for higher flow...

I called Grundfos and even one of their engineers wasn't able to tell me the exact max pressure based on the SQF curve. I did get clarification that according to the curve, if the pump was at 262ft of head it would be making 17gpm. I also got clarification that it is indeed Centrifugal. I'm...

Hi Cary, Thanks for your reply. My water level is around 30ft, but accounting for some pressure loss I was aiming for somewhere in the middle of those curves. Something like 120ft of head and 40gpm. As I read it, the pump will still produce around 16gpm at 262' of head, so I don't believe that...

Is this a suitable 1-1/2" poly drop pipe? https://www.homedepot.com/p/Advanced-Drainage-Systems-1-1-2-in-x-200-ft-CTS-250-psi-NSF-Poly-Pipe-in-Blue-X4-150250200/205909054

Good call on the centrifugal vs helical, I have been warned about this. I remember Cary's comment about pressure tanks taking off like a missile from a helical that just keeps building pressure. I am virtually certain that the 30-sqf-160 is centrifugal. The Helical pumps have a very different...

Hey all, I am going to be installing a SQFlex 30-SQF-160 to run a solar irrigation system on my farm. I am going to be installing a CSV with it to reduce the cycling and I'm trying to figure out the maximum pressure my pump can build to properly size my poly pipe (200psi vs 250psi), and the CSV...

Hi all, I am collecting all of my parts and fittings for a pump and tank install for my farm irrigation. My setup will be fairly standard, Pump>CSV>Tank Tee>Ball Valve> Then sent out into the yard in poly pipe. My question is would it be ok to install a 100 micron filter prior to the CSV? I...

Awesome thanks for the explanation!

Oh that's very interesting. Maybe I have been making a mistake when looking at pump curve charts. Should I be taking into account the pressure required at the top and adding that to the total head when reverencing a pump curve chart?

Hi all, I made a last minute decision to go with a SQFlex pump over my SQ that I just received because I'd like my system to run PV direct. I have a CSV so I'd like to choose one of the centrifugal SQF's so I can use the cycle stop valve. My well is 200ft deep with a 27ft static level. My...

Hi all, I am building a farm and I am about to install my irrigation main lines with frost-free hydrants for my above ground distribution into timers. I have recently read about the cross connection/contamination risk the weep holes pose to water supplies. The health department doesn't require...
