Re: [papercreters] Trash Pump Intake Hose ideas?

That is an interesting point. I never tried sucking pc more than about five feet, though that worked fine. I first made the mistake of using a canvas fire hose on the output of my 2" pump and found that any little kink caused a blockage that soon became a solid lump of compressed pc from the pressure behind it. I started using some large irrigation tubing with a smooth inside and made sure I did not kink it. That works great and I am able to pump 100' through 2" tube, with a 25' head - to the top of a dome.

I think that it would not be a problem to suck pc fifteen feet or so as long as there are no obstructions or restrictions, but there is only one way to know for sure. It looks like a fairly long suction hose that Mikey used in this video though it is hard to tell from the quick cut.  Ken, I'm curious about why the pump has to be so far away from your mixer and around several corners. I would be tempted to mount the pump on the tongue of the mixer and tie it directly into the bottom of the tank.

Hey Ken,

 

Maybe go scrounging to your local concrete pumping company.  They may have a bit of hose that will do the job. Most likely 4” though.

 

But I doubt you be able to suck slurry very far at all.  Pumping yes, but sucking no...

Subject: [papercreters] Trash Pump Intake Hose ideas?

 

 

I've purchased a 3" trash pump for pumping my papercrete slurry and need to come up with a rigid intake hose for it.

I know that for sections of the about 15-foot intake hose that I can use 3" pvc. But it also needs flexible bends.

These need to be strong enough and rigid enough that they will not collapse during significant suction and will not puncture as slurry is pumped through the flexible portions.

Any ideas of inexpensive or reusable discarded materials that (along with hose clamps) could be used to manufacture the flexible portions of the intake hose? Would need to slide over 3" diameter pvc and clamp tightly to it.

Alternately, are you aware of any flexible, semi-rigid hoses or tubing material of 3" diameter that I could scavenge or re-purpose for the entire intake hose? I need the hose to be about 15 feet in length and to make several 90 to 180 degree bends.

Locally, 3-inch diameter semi-rigid intake-hose material made for trash pump (and water pump) use is selling for about $8 per foot.

(The stuff is advertised for 99 cents per foot on eBay, but they make up the difference with outrageous shipping/handling fees. It still comes out to somewhere north of $6 per foot.)

Would like to apply some ingeniuty -- yours and mine -- and beat that price and maybe, in the process, make good re-use of something that otherwise would be clogging a landfill.

Ideas?

Thanks,
ken
