Mono pump in action

[Tony]

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

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:

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.

[julianf]

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)
