Help with pump

[aquaepiphyte]

Hi all,

I was hoping someone might help me with a pump question. I will be running a pump from my reservoir in the basement, to my first floor where I house my ebb and flow system.

I am going to need a pump that can handle moving the water from ground level up 14ft, and hook into about 6 2gph pc drip emitters. I need a pump that will get enough head to go up 14ft with enough pressure at the end to allow 6 pc drip emitters to function. The drip emitters are going to be attached to poly tubing 5” between with a total of 36” of poly tubing. I was pointed to the TNC 1/4 HP Pump but someone else said it may not be powerful enough and another suggestion was ECOPLUS 240 (3/4 HP, 26GPM) booster pump. Any help would be greatly appreciated.

Thank You!

14ft head equates to 6.22psi, with the pipework loss and drippers you need a pump that can deliver around 15-20GPH at 25ft head.
The TNC 1/4HP has a maximum head of 17.2ft so its not strong enough.The ecoplus 230 (1/2HP) will do 1380GPH at 25ft head..slight overkill :wink:

Something like this would probably work, seeing as you only have to achieve 12-gph.

Max head is 11.8-ft at almost 70-gallons...it should do 6-gallons at 14-ft. That Ecoplus 240 would be overkill, IMO. Or, there's this one that is rated with a max head of 17.3-ft; could you add a manual on/off water valve close to the pump to ultimately adjust the output pressure, if need be?

Look at the Iwaki pressure pumps...Those things are sweet

Thank you for the responses. I really appreciate the help. If I needed to get 14ft of lift (head) which would be about 6.22psi, and I had a pump that produced 15-20gph...is psi a concern. I am worried that a regular little giant pump would not give me enough force to get it out of the drip emitters (it says that they should operate at 25psi or so?

Any clarity or pump suggestions are appreciated..I guess I am a little confused

The Iwaki pump does look like it would do the trick..the question is which model/gph rating?

If the drippers are rated for 25psi ideally you`ll need 12gph @ 25psi, plus 6.22psi to lift 14ft and a little more to account for any pipe losses. 12gph @ 35psi (79ft head) would be plenty :wink:

Aqua.......You require a completely different type of pump that produces high pressure at low flow. You need a diaphragm pump like this one:

Or 100 psi like this one:

An Aquatec CDP-8800 will do about 14GPH @30-40psi, quiet running and continuous duty.
Might find them cheaper than this

I was looking into the diaphragm pumps initially but was worried about adapting them to 3/4" pvc piping. The line I ran through the wall is 3/4" pvc to a poly tubing adapter. I do have a flow regulator, but would be concerned that the pressure buildup in the line would be problematic. Most of those pumps seem to require 3/8" I.D or so flex tubing, but how would they operate on 3/4" pvc? I'll also have an inline filter attached to keep the drip emitters from clogging. Sorry to be a pain in the ass, just want to make sure I get the correct pump.

You should be able to cobble something together using john guest fittings. Convert the end of the pvc pipe to provide a 3/4" thread, maybe a short length of copper tube and a brass fitting (tap connector or washing machine outlet maybe)

Sorry, I don't understand your question. Pressure buildup?? 3/4 pvc can handle about 200psi or something. A pump is a pump. Use any line that you like.

look at the specs here I think the 40 rlt is what you need (but I've been accused of over doing things)The rlt is for high head low volume and the rlxt is for high volume low pressure

 

[Me2]

The rlt40`s max head is 21.3ft, or about 9.5psi.
