Yes you did (Describe a centrifugal pump).

:S Wait- did I just describe a centrifugal pump ?!?

Not quite but what is going on under the shredder plate? Read my first post.

If stand by what I said, I do admit however that most of my Disposal experience has been with In-Sink-erator models both home and industrial.

And these do indeed pump.

Watch how fast water flows out of the sink with the unit turned off, Now turn it on and see how fast the sink drains.. Why the difference.. Because the disposal is pumping.

Not all disposals pump. Mine didn't.

Yes, someone has, A few years ago someone posted a thread in one of the forums here showing photos and all.

There are many types of pumps, one is centrifugal A disposal is this kind of pump, by "Throwing" liquid toward the outside and putting a "Vent" (outlet) there it pumps. and this is exactly how they are made.

In addition a Garbage disposal literally chopps/grinds semi-solids into little bits.

The macerator pump is two devices,, If you look down the 3" throat you see the macerator, Little blades, may be metal or plastic, which stir things up and encurage breakup.. What you do not see is the pump which is below the metal plate, I am not sure what the proper name for this pump is but it works by varying the size of chambers as they turn in an offset circle (the moving disc and vanes and the compartment they move in are not concentric) so as the wheel turns the vanes compress and then pass the outlet forcing the fluid out. Then they expand and suck down another load from the macerator compartment.

Work good they do.


One suggestion, If you decide to buy a FLO JET like I did (portable) and use it only when needed.. Put a large flat screwdriver in the case with it.

on the bottom of the motor is a slotted shaft.

Turn it (I believe it turns clockwise) a few turns before hooking up the pump.

Saves fuses and @*(#$#@! ing.

I made one with a Badger disposal I bought at the local Habitat Restore for about $8.

Probably spent about $20 on various parts to make the macerator.

I had heard of the idea - had not seen any directions; but the result was similar to Steampunk Workshop above. It will pump 100 feet using 5/8" hose. It will lift (outlet higher than pump) about 10'.

Only use it now and then, but when needed; its' a great solution.

Thanks for all of the replys guys.I had bought a new Badger model on ebay a few months ago but couldn't find the directions again, it was the link posted. I too had thought about using the dishwasher inlet for a flushing port; and I just looked in it thru the discharge port and it does have about 6 vanes on the bottom of the plate so I guess it can pump somewhat..Thanks again.
