In swamp cooler land, we get leaves, bugs etc aggregating in the water in the bottom of the cooler, and a simple plastic mesh or wire screen basket in which the pump sets serves to keep such stuff out of the pump. Its like the little plastic basket your strawberries used to come in, but you could make one by drawing together a rectangle of nylon screen wire. Any place that sells pumps should sell the baskets. Tom

So Tom, if my pump hypothetically quit working before I got the screen because I didn't wait - hypothetically - which of these would be a better replacement, or would it matter:

This black pump

or this blue one

The one I have is most similar in appearance to the blue one.

Never bought one, just came with this saw. Thanks for any input.

I'm not sure I see a difference. Both sort of have a screened opening at the bottom that should help keep them clean.
I suspect the only factor for pump selection is pump capacity. Some pump more water (oil for you) per minute and hence are stronger. Stronger might be better for moving a viscous material like oil with rock dust in it, so stronger is probably better. Too much flow might be bad but you can always constrict the outflow tube and constriction is not bad for the pump because these work with a simple propeller in a relatively open apron at the bottom. I know we used the highest capacity pump (probably this 7500) and felt like it hurled a lot of oil on the blade but that was adjusted to not constitute a problem. Oil should be pointed down at the upper front of the blade so that it is not hurled off toward the front (i.e. on your white t-shirt). I hope this helps, I'm no expert on swamp cooler pumps, but do know people use them long and hard and they are cheap and available. Tom

Thanks Tom Peruano

Hypothetically, I like little giant...
Some thread here or some rock group said they were the best for drop saws, which are probably the most abused of saw pumps.

thanks Rockoonz - I looked at them but already ordered the other. Meanwhile I will see if I can look at the pump I have and if there is any way to inspect the impeller try to clear it if it is stuck. I did order 3 gallons of mineral oil off Amazon - found some for $15 with free shipping, which is the cheapest I've ever found it. Oh and I did get the screen this time too

Now that's a beautiful agate!!!

Leaky bucket, I can relate to that.
Good to see you got things going, I can relate to a lot of your tribulations.
Last week I was just finishing up for the day and as the last slab was finishing up I decided to sweep under the saw, so nudged the steel 5 Gal paint can bucket of oil out of the way with my boot and swept up, retrieved the slab and went inside to wash the oil and grot of my hands, when I came back I found a drop of water in the oil had eaten a pinhole through the steel and my nudge had opened it up. I was confronted with a huge and growing pool of hot runny oil spreading everywhere.
Bonus though, I have been battling termites for a while and could never find where they were getting in, I have been baiting the wrong side of the house, the oil soaked down between the garage slab and the house foundations and suddenly I don't have termites, so I know that they are coming in under the garage slab, so I will relocate some bait stations.

I never stray very far when I am sawing.

Thanks Paul, glad to know I'm not alone in my tribulations
