oil pump for LS14 drop saw

I used to have one of those saws. The pump that came with it was one of those mushroom shape tower type pond pumps with kid of a weak impeller system. I'm sure one of the stronger small sump pumps would be much more efficient and durable. Someone I saw once had a set up where he pumped from five gallon buckets rather than the rather small well in the saw The Northern Supply catalog I believe has quite a few pumps but probably almost any big hardware store or pond supply shop would have them too. The problem with the stock Lortone set up was, when the oil became full of suspended rock dust after a few cuts, the old pump would no longer push enough of the then heavier oil. And, as soon as the oil starts to run low the blade will dry out and grind to a halt and often, dish. As you know, those saws are a giant pain in the patoot because you have to clean a lot and to clean you have to lift the entire heavy unit from the pan to properly clean the sump and the sump really does not hold a lot of oil for the pump to push.....Mel

I tried running one of those with water once. Didn't even finish 2 cuts on a relatively soft rock before the blade was ruined.

Old topic but what's everyone using for a pump for this beast or is the one in link still the best... preferribly a pump with a anti rock screen.

Just a generic swamp cooler pump on mine. Has always worked fine. Am currently using Finevestan 85 oil. 

Did you have to expand the hole in the saw, that's what I'd not want to do

What brand of pump or rather an Amazon link.. my problem I see are most have a larger base

They likely used the brass Teel pumps originally. They may still be available but were really expensive when I had my saw. My original Teel pump was fine but cord was bare of insulation and no easy way to replace it. Back then Little Giant cooler pumps had same round base. The cheaper pumps I see at Home Depot have larger bases with built in strainers.

Well, hummingbirdstones , I want to ask Vince a question. :-(
I am searching the forum for info on how to screen or filter a pump and I found this old thread. We have refurbished an old drop saw and my last task is figuring out how to filter the pump. It is an old Teel pump like Vince mentioned above here. I was hoping to find people who have experience using one of these and can tell me how to protect it from sucking up rock debris. If you know and can offer any info I’d sure appreciate it. I will also keep searching for other threads here.

hummingbirdstones Thanks so much. I appreciate your efforts. This is the pump I’m talking about. It sits at the back left of a drop saw in a little square area. I’m wondering if that area needs a fine mesh screen or if the pump itself needs something wrapped around it or under it. The brass rod in the center spins so any wrap needs to be clear of that moving part. It seems to me that debris would get sucked into the base of that brass rod area both on top and underneath.
