Looking for new water pump

[johnthor1963]

I’m looking for a new water pump for my cabbing machine. I have a 3 bucket set up for settling the suspended particles in the water. I change water frequently when it gets too contaminated. The detached garage I work in has no running water in it or I would plumb something in.
I’m just curious what some of you are using. Any insight would be greatly appreciated thanks for looking.

I use a fountain pump from Home Depot. Most big hardware stores carry them. Just make sure it has enough lift for your application.

I got my pumps at Harbor Freight. Dont know how long I've had them, but its been a good number or years and haven't had any issues.

Most hardware stores should have some.

That peristaltic pump is pretty cool!

I'm pretty happy with the KN pump that came with my cabber, 

but have been thinking it might live longer not sitting on the bottom of the bucket. 

Here's something I just discovered to keep my pump out of the settling sludge.

a Harbor Freight Dirt Guard.

It's a peristaltic pump. This style of pump doesn't actually pass water through any of the mechanical parts. It just squeezes the hose, generating a vacuum that gets rolled a short distance, sucking up fluid. A rotating motor makes this short pulse of suction a fluid movement. Running the pump dry doesn't hurt, it pumps air or water. This style of pump has superior lift compared to other pump types in this size range. You can easily draw water from the floor up to the cabber with the weakest peristaltic pump.

Since the pump doesn't sit in the water, you can have it sitting next to the cabber. With the adjustable flow dial right there I can turn the flow up and down. The dial is sensitive to the full range of the motor, you can have it drip one drop per few seconds, up to a steady stream, and everything inbetween. The hose is so tiny it fits into any water port, I don't worry about it fitting tight, so I can move it from port to port as needed.

It was designed for sucking up high-solid slurries, since the motor is isolated from the muck it won't harm it. I use a larger one to drain slurry. This small one can do it too, just slowly.

This is interesting.   When I was an engineer, I used to specify larger versions of these for pumping corrosive chemicals (because you could get chemically resistant hoses and no mechanical parts touched the corrosive chemicals) and solids.   I may try one for draining the oil sludge from my saws.   Only issue with is that the hoses wear out but as long as you keep an eye on them, you shouldn't end up with a mess.  Thanks.
