Title: Pumps knackered
Post by: jonboywalton75 on June 12, 2017, 03:00:11 pm
My son has systematically ruined about 5 pumps over the last year
When he finally decided to stop buying new ones and to try to find out why this is happening, i realised it's most likely that he is blocking his online filter with resin and running them dry.
When run dry, is it the bushes that will be burnt out or are there internal bearings that need replacing?
Just wondering,  as I have around five of the beggars lying around that may be repairable
If it is easily done, do any of you know of where these pumps, (2 Shurflo and 3 Vyair) can be repaired?
Or are the bushes easily replaced?
Might save him some money if he can get them repaired  i suppose.. Appreciate anyone's help.
Cheers
Jon

Im sure they can be run dry anyway but what is actually wrong with them ?
Are they failing to even run  ?

I have had a few apart over the years , not really much to go wrong  , you have one bearing on one end of the shaft and a brass bush on the other , the bearing can seize or the brass bush could be dry (no longer impregnated with oil ) both fixable .
The brushes could  be worn out , or the armature they touch can be well worn also .
Other than that its only really down to the big lump of copper wire on the motor being  shot or the the pump head itself (triple rubber plunger  thing ) cant remember the name of it , its available as a spare any way .
Put it this way , you have plenty of parts to chop and change , if you can be bothered !

I would guess it's unlikely to mechanically wear out FIVE pumps in a year.
Are you sure it's not an electrical problem that's causing the failures?

All the pumps seem electrically ok, but they act just like they are airlocked

Seem to be spinning, but pumping nothing

My lad can stop a pump working in 2 weeks
I use the same pumps, they last me years

if this is the case best just run without filters , we have been running these pump for over 30 years without filters besides the amount of chems they have had in them in the time there in service never had them let us down like this

Are you using flow controllers?
I ran for a while without a flow controller, using an aquatap to control flow. I burnt through 2 pressure switches on a pump within a month.
Title: Re: Pumps knackered
Post by: jonboywalton75 on June 12, 2017, 06:26:02 pm
I never use controllers, as I said mine last me years used that way

Firstly, you should have the pump BEFORE the DI vessel this way resin cannot block the strainer. Second, no resin should get to the strainer anyway so maybe the vessel internal strainers are faulty and/or blocked? Clean the slits with a tooth brush.

It sounds to me like a restriction via either the pump strainer or vessel strainer. My pump is about 8 years old and never missed a beat- Shurflo.

If its spinning but not pumping i reckon its the diaphragm , thats the triple headed rubber bit i was on about earlier , you can get them from Varitech £18.91 + vat , part no 94-390-06 ,
If that is gunged or torn , that could be your problem .

Just stripped mine down to show you , i have never replaced a diaphragm in 12 years , the good thing is you dont need to pull the whole pump apart to check it , its only 6 screws at the pressure switch end on a shurflo anyway , the diaphram is the white bit , it just pops off from the yellow surround , i have just noticed on mine that between the yellow surround and the aluminium piece connected to it is totally minging , this could be a good place to check too !

If they are the old vyair pumps you're stuffed if you need a diaphragm, they changed the pump about a year ago and don't supply spares for the old ones. If you can easily access the pressure switch your stuffed, if your struggling to even know where it is, you're in luck and it's a new model.

Yeah Dave, the Vyair ones we have  are the new ones.
Anyway, how much do want for Lukaku, the pool need a new striker ;D

i bet your not happy with him jonboy!5 pumps in a year?they should at least be lasting 3 or 4 years (used every working day).ive had 2 pumps in 7 years.i just chuck them away and buy another.i cant be bothered taking them apart and getting parts for them.

he must be doing something seriously wrong somewhere during his working day.


hope you get it sorted mate.5 pumps is ridiculous in a year. ::)roll
Title: Re: Pumps knackered
Post by: jonboywalton75 on June 13, 2017, 08:58:49 am
Yeah Daz, when he's in the kitchen it's like an atom bomb has gone off.
He devastates everything around him.
It's cost him though, I'm not paying  ;D
Title: Re: Pumps knackered
Post by: P @ F on June 13, 2017, 09:06:37 am
Too right Daz , 12 years ago i started up with a flojet 60 , high on amps and noisy as heck , changed to shurflo 100 and have 2 of them now , 1 is 11 years old and the other is 10 !
Neither of them have had anything new at all , the one in the pics above is in bits as it has a noisy main bearing but still works fine , its just a bit heavy on the amps due to extra friction .

Oh and Johnboy , thinking a bit more about it , if the pumps are runnning just not pumping it points to the diaphagm pretty certain , i dont want to tell you to suck eggs but i think that shurflos are not self priming , the water will need to be raised and not just lifted from a bucket , but i reckon you know that anyway , also even if you run it when dry i think you should hear a rapid puffing from the outlet , not noisy but detectable .
Title: Re: Pumps knackered
Post by: jonboywalton75 on June 13, 2017, 09:25:46 am
Actually Rich, you're not teaching me to suck eggs, what you're telling me is very helpful
I'm not mechanically minded at all.
Are you saying that I may just Need to prime the pumps properly?
I have suspected the diaphragms in the past
Title: Re: Pumps knackered
Post by: jonboywalton75 on June 13, 2017, 09:27:22 am
I'm also wondering now how the heck he manages to knacker the diaphragms so easily
I don't work with him so don't see all the crazy things he does ;D
Title: Re: Pumps knackered
Post by: P @ F on June 13, 2017, 09:44:36 am
I find it hard to see diaphragms failing to be honest , i have never known anybody that had one go , but if as you have done and Daz does , to just replace then it would not be common knowledge , its just that im a sucker for pulling things to bits.
I would in your shoes check priming of the pumps before anything is even undone , i have in the past got a 2 litre bottle with the bottom cut off , taped on a bit of hose to the pump and put the water in making sure the water is raised above the pump , or just go staight off tank if its easier to do so .
You just have to see it like a hospital drip bag , with the patient being the pump !

Hey wouldnt it be funny to see some geezer called jonboy selling a load of pumps tonight in the stuff for sale section  ;D ;D ;D
Would be a nice outcome eh !

Hey Rich don't get cheeky now ;D
My son is capable of putting it in wrong way round(apologies if you are reading this son :o)
I'll have a mess around and see if I can resurrect these pumps
Title: Re: Pumps knackered
Post by: jonboywalton75 on June 13, 2017, 07:54:07 pm
Took one apart just now
Seems perfect
I'll have a good go at priming it tomorrow and check for pressure switch faults

I ran for a while without a flow controller, using an aquatap to control flow. I burnt through 2 pressure switches on a pump within a month.

Got a feeling it's pressure switch  problems with the Shurflos
Thanks Chris

Both me and my son fill up through the di's
We never pump through them
He gets a small amount of resin in his tank, so maybe a problem with the di's, as you say Peavey

Thought so.
There's a mod you can do with a relay bought from maplins that protects the pressure switch, though I can't remember the part or how to do the mod :-[
It was a few years ago I done the mod, it worked for me, though I ended up going back to a flow controller as the one I use from purefreedom has a built in battery charging facility.
Perhaps someone like spruce will remember exactly how to do the mod.

Post by: chris turner on June 13, 2017, 10:34:48 pm
Another question I forgot to ask is where is his pump mounted?
If it is to high above the tank outlet then without a non return valve the pump will airlock and not be able to prime itself.
If this happens continually then the pump will fail.

Went to Maplins
Got pressure switch
Fitted it
Did some mods to his setup
All working, Woo hooo
Cheers for all the help
Hopefully won't happen again

Aint got any spare pumps goin mate have you !

It does seem strange that the pump would run like yours were with the PS gone , thats why i didnt consider the PS , it has 2 lives and surely with a broken circuit it should not have even fired up , well another lesson learnt here today , you will have to attack the Vyair pumps next , gonna be the same issue for sure , glad you got it cracked Jon , not bad for a 75 year old are ya  ;D ;D ;D

Post by: jonboywalton75 on June 15, 2017, 08:48:15 am
Actually Rich, I think that there are different issues with one or two of the Shurflo pumps
One spare we had worked fine as soon as I fitted the new pressure switch
Another was spinning but we couldn't seem to prime it at all
Now we've got him working, I was thinking of fitting a speed modulator  so we can protect the pressure switch
I used to use one and just leave it set at 100%
I think Maplins do sell something like this so I'll get in there and maybe we'll stop burning pressure switches out.
Anyone know which modulators are any good?
I don't want to bother with an expensive controller that I'll just leave set at maximum.
Cheers for everyone's input
