I have a feeling they are talking about your every day hand pump for a bicycle tire. An accumulator has an air filled bladder in it.

it seems i had my terms are confused, didn't realize an accumulator was different from an pressure tank.

what im looking to do is pump nutrient solution into a pressure tank from a reservoir, is there any kind of pump i can buy that would be capable of doing that.
hand or foot powered preferably.

Its not a bicycle pump, its a hydrostatic test pump They`re used to pressure test plumbing, pressure vessels etc. Because they deliver low flow at high pressure they are used with an accumulator, ideally it needs to be a 16 bar (232 psi) type so you can make use of the pumps pressure. Its cheaper to use an electric pump with tanks that have lower ratings like 10 bar. This one puts out 45ml per stroke at any pressure upto 725 psi. If you buy a cheaper pump check the output specification, some only do 7ml- 12ml per stroke
You might find one cheaper than this if you look around. It must be the latest version cos it has trendy red handwheels

thanks a lot dude, this seems to be the pump i need

question, im worndering if ill be able to disconect this from the accumulator in my flowering system and switch it to my cloning accumulator with plain water. does this pump have some sort of quick connect?

The pump has 5ft steel reinforced hose rated at 400-bar (5800 psi) with a female 1/2" plumbing fitting on the end, prolly be NPT for you. Use a tee on the tanks and add a 1/2" inline valve to one side which will give you the male thread for the pump connection and it doubles as a tank drain. There is a seal inside the hose fitting so it doesnt have to be cranked up all that tight...5 second job.

sweet just found that same model for $200 brand new. $130 savings

question am i going to be able to run a hose into a resevoir from this pump or am i going to have to be content with filling the red box with solution.

The pump doesnt have postive suction so it has to be gravity fed. You have a couple of options,
1) use the red onboard tank which holds about 12L (3.17us gal) but bear in mind the pump wont be able to pick up the last inch or so
2) Undo the 4 bolts that fasten the pump to the red tank (all the pump components are attached to the aluminium plate) and make yourself a new mount out of 2 pieces of angle iron bolted to a sturdy timber frame (2x4`s). The combined depth of angle iron and frame wants to be at least 8-9" to provide enough room below the pump components so you can attach a hose to the intake. A 1/2" bore hose is a snug fit. Get yourself a 5 gallon bucket, plastic jerrycan or 50gal waterbutt (as required) and attach the hose to it, not forgetting to fit an inline valve so you can turn off the flow.
If you opt for the 5 gal bucket you`ll need to install a 1/2" John Guest tank/bulkhead fitting near the bottom so you can connect the hose to it. If you make the timber frame longer at the front for the res to sit on, it will act as a counterweight.
Depending where your accumulators are located you can leave the pump where it is and use a couple of valves to route the output to the right tank. Saves lugging the pump from A to B.

option one seems to be the easiest, i can just keep filling the tank with a pitcher. just ordered the pump.


two questions. do you think a 275 gallon tote chopped down to 3 feet will make a good flowering chamber. like the one set up in this thread. there basically 4X4 feet and i can get them for $50
Medium pressure drain to waste Aeroponic system?

also how many mister nozzles do i need in a 4x4 grow chamber? ive seen conflicting information.
