Peristaltic pumps for waste slurries?
Peristaltic pumps for waste slurries?
(OP)
I'm looking at using peristaltic pumps (hose pumps) for waste slurries: TS something up to 15%, containes grit and maybe fibers ...
This is a use case where so far we are considering PC pumps. The reason I'm interested in peristalic pumps is mostly the wear on the rotor stator package, the hoses are at least cheap (unless I need to cahnge them three times as often ...). We'Ve yet to build our first waste plant with a PC pump in this specific duty, so I don't know for sure how long the wear parts last.
The duty would be to feed slurry from one tank to the next, not to feed process equipment. I think that makes the pulsation issue less severe than it could be.
Some questions I ask myself now, and that I'll ask an Albin rep in a few weeks:
- how do the pumps handle longer fibers? (My guess is quite well, but ...)
- With lots of solids, would it make sense to use a large pump with a smallish motor
- pulsation, how severe it is and what to do
I'm I wrong with my assumptions allready? What else should we be aware of? If someone can share experiences, that would be appreciated!

RE: Peristaltic pumps for waste slurries?
Pulsations become an issue the higher the pressure is. But as you are just planning to pump from one tank into another the pressure does not seem to be that high. And Pulsation dampeners can also be added later if that becomes an issue.
I would definitely oversize the pump to get it smoooth running. The grit can become a problem if the particles are big.

Our pretreatment limits the particle size to <12mm, most SS will be far smaller but individual longer vibers can be present.
If yo uwanted to destroy a peristaltic pump, what wold you pump?
