Pump with Pressure Tank ???

[tec0]

Well with basically no water ALL the time now I am forced to upgrade to a lager water tank and to that end this damn pump. It has no diagram or flow indication so how do you connect it? I don’t know! I asked the people that work with the stuff and they are more interested to come and do the job for you at a cost of R450 per hour labour but no advice.

So I included a photo that shows you what I see now I don’t know where the tank is to be connected “source” or the “outlet” any help would be appreciated

Normally the inflow is the lower point - outflow is the higher.

the advice is always free from the supplier...who supplied the unit?

i am assuming you have a bladder on top to prevent it from switching on and off...with a pressure control switch etc?

what are you trying to achieve?

complete installation? piping and electrical?

If you have no water then maybe the water table has dropped below the level that your wellpoint is sucking from......assuming this is a well point pump.

If that's the case a newer/bigger/better pump won't help.

As Dave suggested the suction is on the front and the discharge is on the top. Please be carefull, many pumps aren't rated to run dry for extended periods. Damage cause by this won't be covered under warranty.

Here's a drawing of part of a system I specified a few years ago, not sure if it's relevant for your setup or not unless you can give more info..

Well what I am hoping for is to get the water from my 2500L tank into the pump with the bladder and from the pump to my house’s pluming. Well that was the plan. But I will be happy just to connect a hosepipe to the outlet of the pump so that I can utilise the water.

How difficult can it be? The place where I got the pump from was about as helpful as a brick in the ocean. But If I can’t get it going by the end of today I am selling on... No use I have it and I can’t use it.

Schematic would be something like this them.

ok

This is what I am dealing with and yes I have downloaded the useless manual form the website. Seriously is it that difficult to put 2 stickers on this damn thing. One stating IN and the outer OUT?

Well this is what you see when you get your pump with the tank pressure thingy... So I am thinking that the best way to test it is by turning it on see if you can identify flow.

I am thinking however that the top one is the “IN” and the other hole on the side is the “OUT” because of the location of the silver pipe. Well if I am wrong I am wrong...

[daveob]

why not connect both in/out to a bucket of water and turn it on ? Water will pump out the bucket and back into the bucket. You'll feel the suction and flow on the pipes in the bucket.

Alternatively, you could crawl the internet for days trying to figure it out.

Sometimes, you just gotta 'do'.

[tec0]

I am basically doing that “loop both ends in a bucket and figure it out stage” the problem was I had to get some more fittings. So hopefully I will get it working and then I will post it on the net. The thing was I asked many people this question showing them the pictures or sometimes the pump itself and they also had no clue. So my own stupidity aside... I will probably get it working but you get so angry because if something goes wrong it is an expensive fix.

I've never seen a pump connected this way before, I think the braided hose you refer to is connected wrong. The front of the pump is 'in' (suction) and the top of the pump is 'out'(discharge). Connect the hoses and the electrics correctly, undo the small hexagonal brass nut and pour a litre of water into the pump before you switch on. Bob will be your uncle for sure. The schematic above is pretty close to what you're aiming for. The only thing that I didn't show on it is a check valve on the suction side of the pump often referred to as a 'foot valve'.

Have a great weekend tinkering, I can tell you're looking forward to it.

on this page is a manual you can download for installation...use and maintenance.

if you cant understand how to connect it and run it after this...best you spend the R450 to get someone to do it

[AndyD]

Well I was wrong about the braided hose but the suction is definitely on the front.

[tec0]

I was at the store where I got my pump and they got a new shipment in today. The box is the same and the pump is still the same thing. However it had a nice sticker on the side. Now my box doesn’t have this sticker so I never knew. But here is the truth:

[AndyD]

That's quite impressive. Usually it's in Chinglish and ambiguous.

Google Speroni Water Pumps and you can download the manual for particular model
When in doubt, read the instructions LOL
