Mag drive 36 for drippers?

[cesartime]

I have a mag drive 36 (3600 gph) which i was going to use for bio buckets, but since the summer is coming and i dont want to spring for a chiller to combat root rot, I was wanting to know if i could use my pump to run some drippers, or possibly put the pump on some sort of speed control so i could run a drip to 20 3 gal buckets of coco under 3 600's.

If it is possible could i just use a speed control like i use for my 8'' vortex, or does the mag-drive pump demand something different to reduce its output, is reducing its output even necessary? can i run some sort of high pressure sprayers that can utilize the pump?

any help will be greatly appreciated.

plumb in some ball valves. Do it right at the outlet, make it convinient ofcourse. This will allow you to bypass right into the res. This also helps keep things moving in the res. You may want to add a few to the line splits also to make sure you have even flow to all lines which effect the drippers themselves.

I agree with dasme, Consider placing the ball valve as far away from the pump as practical. If it's placed too close it can cause the impeller to cavitate. On either the input or output of any water pump, any bends or restrictions should be as far away from the pump as possible. Also your mag 36 will work a lot better by increasing the diameter of the pipe going in & out particularly on the input side. The Mags have 1inch openings, try 1.5 or 1.75 diameter pipe.

any more suggestions?

I just finished mine the other day so i could help you out a little. If you can bring water in the room on a line you can do it somewhat like mine. I dont really think i left anything out.. anyways here is a pic of my res, pump, and valves.. so i can explain.



There are four valves, starting from the right. The far right valve(1) regulates my fresh water intake. The next is for the pump its attached to(2), third is to fill/mix/drain my res(3), last is the valve used to control the flow to the drippers(4).

This lets meassuming they are off)
Turn 2,3 on to mix res, fill a bucket, drain res(pic)
Turn 2,4 on to feed from the res
Turn 1,4 on to feed fresh water
I think that covers it

thanx a million.

Hazey..........That`s the shitdiggity for simplicity ...........Major respect for the hands on approach.....How could we automate that to work off timers feedwise for the new guys tryin to learn?.......The ball valves can be opened to a certain point to regulate how much pressure the pump`s pushing to the drippers,right?......How does that affect the pump?.....Looks like you`re drain to waste in coco/ perlite? ..........How many times a day do you feed?........Thanx again for the info and pics .......Peace.......DHF........

I know we have talked about this in pm, but for all the others. This is a organic soiless mix not coco but it is drain to waste as you guessed. I think the best thing to do is to use a digital timer or something along those lines that can do shorter time periods, as you stated you could also use the ball valves to regulate the flow. Im not really sure about the effects on the pump to tell you the truth i use a 1000gph magnetic drive pump, im not sure if the impeller in a magnetic not turning will ruin the pump anyone know?
