Has anyone got any experience with setting a pump to make a continuous gunge shower?

Holding gunge overhead in a bucket is a lot of fun, but there's a limit to how much I can put up there. (weight and volume).
I was thinking with a pump, I could deliver a much greater volume- a potentially "infinite" gunging by putting the intake pipe in the bath and looping it around.

Ideally thinking about pumping 10L/min of gunge up to a height to 2m, but 5 l/m to 1.25m would do the job. (just dripping out the end of a hose- no fancy shower head or anything)

In terms of gunge consistency I'll need to mix it runnier than the extra thick I normally use- Is MessySupplies standard Natrosol/MSGunge about the right starting point?

You're looking at a very privcey slurry pump

Something like a screw pump would probably work well for gunge. Just by a quick search you'd probably be looking at about $200.
