Concentric/Haldex Hydraulic Pump - 13.6 GPM, 2-Stage, Model# 1001506
Can't beat it
I just replaced the aging pump on a Yardman 27 ton log splitter that was so worn out it wouldn't split anything bigger than 4 inch diameter. The Yardman part number had been discontinued and replaced with another part number that had similar specs (11GPM). I found that part available several places online for between $371 and $768. I compared the photos to the photos here at Northern Tool and it looked like the exact same pump. I opted for a slight upgrade by going for this 13 GPM pump because the 11GPM pump from Northern Tool uses a 3/4" inlet port and the old pump uses a 1" inlet. This 13 GPM pump had the required 1" inlet port which made installation a bit easier, but I'm not sure I did myself a favor since this pump is a bit too big for my little 5hp motor. It pushes the ram a little faster, but it also requires a bit more oomph from the engine. If I run into a very thick log, I have to bump the lever a few times to keep from killing the engine. That's what I get for using a pump that's rated for 6 hp on a 5 hp engine. It still works great and once I figured out to bump the lever a few times, I think it actually splits faster due to the higher flow when not loaded. As far as fit is concerned, the old pump used long bolts that go all the way through the pump housing. This pump uses short bolts that just clamp the flange. All the holes lined up perfectly and the only thing I had to change was using shorter 1.5" bolts. I also had to purchase a new half coupling with a half-inch diameter hole (conveniently also sold by Northern) because the old one had a 7/16 hole. Also, the old pump had an O-ring style output port where this pump uses pipe thread. I found that the O-ring adapter that came off the old pump actually works on the new pump, but the threads are a bit loose. I'm planning to replace it with the proper fitting one of these days, but for now it's working without leaks.
Bottom line: This pump was very easy to adapt into my old log splitter and saved me a boatload of money over buying the "correct" pump from the normal channels.

excellent spilter pump
This is a great pump for a spilter. It will push through any wood you have. I run a 10 hp on the pump with a 6 inch diameter cylinder and a 14 inch high wedge this pump never let me down highly recommend it for a spilter pump

Concentric/Haldex Hydraulic pump
I just replace a single stage pump in my wood splitter with this pump and I can't believe the difference. I can split wood with big knots and it just pushes it through. I am vary pleased with this pump and would recommend it to anyone that wants to get the job done.

I purchased one, to replace my old log splitter pump.
My old pump had the same mount holes, so I only spent 15 minutes to replace the whole thing. With a Honda 5 HP engine it runs GREAT. After a year+ & over 25 Cords it runs like new!

We purchased this pump for our woodsplitter. It works great! We split 7 cords of wood in two days without a problem. We also purchased the hydraulic ram and we will be purchasing a new 10 gallon tank this year. Northern has been our "go to" company for a variety of items over the years. Thanks for providing excellent products and service.

Perfect for Log Splitter
I bought this pump to replace a somewhat smaller pump on a burned-up log splitter I've been restoring, even though the manufacturer told me it was too much pump for the Briggs 675 engine I was running. As it turns out, the Briggs runs it without any trouble, even at 7,000 feet. The trick was to lower the "initial loading pressure" to around 450 psi, to keep the engine from stalling when the ram first meets resistance. At that point the 2nd stage kicks in very smoothly. This is a well-built pump that can be adjusted to run with a small engine.

I bought this pump for a log splitter i built, and it worked great. I had to build my own mounts to fit the motor, but once i got it put on it worked great. I couldn't be happier with this pump.
