Laguna Max-Flow pump

  • We are currently upgrading MFK. thanks! -neo
The pump I have plumbed vertically is held upright with rigid plumbing (see pump to the left in the picture below).

The pump that is laying horizontally goes out through the side of my sump via a bulkhead fitting then hits a 90 degree elbow up to the tank. I wouldn't have done it this way, but I had originally plumbed the tank for an external pump, but that didn't work out so I decided to still use the bulkhead on the side of the tank.

I've had stainless steel hose clamps on barbed fittings coming from the pump for about 2 years and still no signs of rust.

PS- if your pump is pushing > 2,000GPH at whatever your head height may be, it's best to expand to 2" plumbing in order to keep friction loss to a minimum. Using 1.5" will work, but with that much flow, 2" is better.

Thanks for the info... i;m using a laguna max-flo 2400gph pump.. my tank is only half of your tank... 300gal with a 125gal sump. which i build myself with 5 sections of baffles and if everything goes well with all the water filled and pump matching the pump and overflow it will hold about 70gal of water in the sump.. thanks to mfer's calculator of course.. my 1st baffle will be filter socks, 2nd will be mechanical filteration,3rd will be matrix, 4th will be spare but matrix will be filled into it, last is pump with 3 jagur 300watt heaters.. i have brought 20liters of matrix so just like you but i love that mesh bag that's holding your matrix.. where did you buy those zip bags??
 
Sounds like a nice sump.

I got the mesh bags on Amazon- if you do a search for "hosiery wash bag" they sell all sorts of shapes and sizes. Looking forward to seeing your setup once everything is up and running. 20L filled three of these bags to capacity:http://www.amazon.com/Honey-Can-Do-...d=1372123481&sr=8-2&keywords=hosiery+wash+bag

If you overfill the bags, it puts a lot of pressure on the seams and they will tear relatively quickly...at least that's been my experience; the bags that I didn't fill as much are holding together a lot better than the bag that I crammed a ton of matrix in.

Good luck!

i don't think i can change back and forth on this setup that i have.. all my fittings pressure side of the tank are 1" returns.. so not sure if i can make 1.5 then change to pvc 2" back to 1" to fitting.. guess i have to go to home depot or lowes and see what they got for me.. but i'm definitely going to change pump then flexible hose then to PVC.. this will lessen the vibration of the pump..
