Check this out - my poor old mono labouring through some WVO, using the footer valve/filter that KH gave to me many years ago :)

Empties it quicker than Julian does a glass of red :P

And a lot quieter.
Always a worry photographing into a barrel that you'll drop the camera.
-
That was my Android phone, should've turned it to the other orientation (landscape) in hindsight, ah well. Yes was a little worried!
-
I cant see what you have on the end of the pipe?
I cant recall what its called (and now cant find a photo) but on mine, ive got this little bsp 'cage' thing (mesh filter) but the trouble is the surface area of it is too low, and the holes too small, so it gets blocked way too easily.
I want something on the end of the suction pipe, so as to avoid sucking up snails etc (i never used to have a problem with snails until we moved, and now... they dont half block pipes well!) but have not been able to find something suitable.
Ive considered a washable cartridge filter, but id most like something 'snail proof' on the end of the pipe.

Yes it's one of these:

The one-way valve is useless as it jams open on the gunk, not that the mono cares as it self primes anyway. And it does block frustratingly regularly,
I'm experimenting with a Y valve on the pump discharge (Keith gave me one at the last BBB), so far it's OK but I've yet to graduate it to running without the filter on the footer valve as well - though I've picked up a 1" coarse stainer to try at the pickup end - one of these:
http://www.ebay.co.uk/itm/1-SUCTION-HOSE-STRAINER-WATER-PUMP-DRAINAGE-IRRIGATION-/120546380508
I think the Y valve could do with extending somehow to capture more without blocking but we'll see. That or graduate to a full 10" filter housing.

Wait until one slithers up the angled waste pipe on the outside of your house,great fun when the washing machine discharges into it!

Is that veg?
It looks really dark.
-
I keep looking out for a cheap mono pump - they seem to be ideal for moving thick veg around

No good looking on ebay ... Tony and me got that stitched up with automatic searches!
But if you can find one they really are the business.
-
Ive seen them on ebay reasonably frequently - maybe every couple of months? If you wanted one for under £50 i think you would have to wait a while, but if you were happy to spend up to a ton, i think you would get one fairly quickly?
I think mine was £40, but it needed a new rotor and stator - i think it worked out about £100 all in.

WVO always looks dark in 60l drums plus the black layer of BCBs on the bottom doesn't help :)

Just spotted these on ebay -

The tail in the photo is 3/4 bsp, but that could obviously be swapped. The cage looks like it would block less frequently than the mesh ones, but still stop snails etc from getting up the pipework.
Not too bad a price either.
-
Oooh nice find :)
I like that.
At the moment I'm using 1" reinforced hose (the trouble with braided is that the pump sucks so hard it just goes flat!). However it's just water hose and goes brittle and cracks after a few months. Any ideas what I could use that a) won't get sucked flat b) will stay flexible with oil use?
Edit: Thinking about it, I have got one of these on a shelf somewhere:

That is what i use on my mono pumps suction side. Its not very flexible, and if you do manage to kink it, the wire inside keeps the kink, but, if your application doesnt need a load of flexibility, its just the ticket.
You can buy it off ebay etc too, but, when i looked, buying a 'kit' from screwfix was the cheapest way to get the hose itself (the plastic parts in the 'kit' break quickly, so dont buy it for them)
-
Thank you Julian, that is just the ticket! There's a Screwfix right by where I work so I'll go pick that up tomorrow. Includes jubilee clips too, bargain :)
-
Includes jubilee clips too
IIRC they were especially bad...
-
The best clips I've ever bought were stainless ones from a Chandlers, but they were a quid a pop. I'm not surprised the Screwfix ones aren't great...
-
Those T-bolt clips are about £12 for 10-off from ebay.
I can get nice stainless ones from a military surplus warehouse near here for pretty cheap (i think about 30p each?) but, by the time theyre posted, i dont think it would be worth it?
-

I won't be buying any more stainless ones from BES.
The slightest whiff of a 'torque' and they slip.
Elastic bands out perform them.
-
The ones i got from the ex-mod place were the type that the band actually has holes in it, rather than the type where the band is just bumpy.
If im feeling especially enthusiastic, ill get the camera on them tomorrow.
-
Are these mono pumps the ones with like a shaft with a spiral on it the fits into a rubber, inside a housing on the end of the pump? Some where on here there is a picture of one, and it looks very similar to one i have kicking about in the shed. I had it apart one day to see how it worked. Ancient thing, with a heck of a weight in it.
I guess they are ok for oil, but I would have thought bio might destroy the rubber.
-
spot on -
the stator is the rubber bit
the rotor is the worm bit that, well, rotates
bio would kill the rubber, unless you were flash, like the other julian, and splashed out on a viton stator.
-
theyre actually called -
progressive cavity pumps
mono is just a brand name (like hoover)
-
Cheers. The stator looked pretty ropey in this one anyway. Didn't know replacements were avaliable. The age of it, I was suprised that they are still about.

Picked up just now, plenty flexible enough for what I'll use it for :)
-
good stuff - glad its what you wanted.
as i say, the only issue ive had with it is when my mono travelled from the top of the bench to the floor very quickly - it put a hard kink in the hose just by the hosetail, and i couldnt reform it well (ended up cutting the end)
i would imagine the same if you trapped it under somthing heavy etc - so just watch out for that one : )
-
let me know if you swap the footer, would you?
i should really buy one of those brass ones i linked to before - i think they would be good, but, if youre just about to change, ill wait to see how you get on with the other type!
-
Might scrape a few quid back by selling on the ABS footer on eBay, worth a go a think!
-
Sold the ABS fittings on ebay for £5.95 so the tubing worked out even cheaper :)
-
...making the tube not much more than £1/mtr. Which, im sure is cheap : )
I was using my mono the other day and kept having to scrape the mesh strainer on the end of the inlet 'sucker' pipe. I got sick of it, and vowed id buy one of those brass footer things.
I have done so, and it will be here soonish, i guess. Ill let you know if its any good.

Yep, been there done that...
