More Views


Hard working and fast, this hydraulic 2-stage Hi/Lo gear pump flows 28 GPM at low-pressure with maximum pressure of 3,000 PSI on the high-pressure side.

This 28 GPM Log Splitter Pump automatically changes from Low-Pressure/High Speed to High-Pressure/Low-Speed at preset 900 psi (adjustable). The body of the pump and the endplates are cast-steel for durability. The 2-stage hydraulic pump is designed specifically for log splitters, presses, compactors and other equipment where cylinder must extent/retract rapidly at low pressure and switch to high-pressure when loaded is met.
Direct replacement for most OEM logsplitters. This fast log splitter pump will mount to any standard 2-Bolt A mounting flange.

    • I bought this pump to power my 4 ft wood spliter and love it. It is hocked to a wisconsin engine and will split any thing I put in it. The price was the best i could find so thanks for that.
    • Thanks for the feedback!

    • can this (28 gpm) pump be mounted with the shaft verticle, pump below engine.
    • Yes, it can be mounted that way.
  • From jc at 2/2/14 7:45 PM
    • can you use a 25 GPM Valve on a 28 GPM pump without damage to the valve
    • It probably won't hurt the valve, it would just build up heat over time if you were to flow the full 28 GPM through it. I would recommend just slowing the engine to reduce output.

    • What rpm should this pump be operated at? Would 540 be to slow ?
    • Yes, PTO speeds won't get you much flow. 3,600 RPM is max flow.

    • I bought the 28 gpm pump and I am very pleased with the speed, I hav a 24 in stroke with a 7 in bore with a 3 in rod that comes out of the cylinder, i put this on my homemade wood splitter and like i said im very happy with the speed, thanks to the ppl at international hydraulic place .. you ppl are great and btw the price is very very reasonable as well
    • Thanks for your feedback! We really appreciate it.
  • From Carlo at 10/8/14 6:27 PM
    • Would you be able to tell me at what RPM should this run?
    • 3,600 RPM is the maximum.
  • From matt at 2/10/15 3:07 AM
    • I calculated the efficiency using this question. HP = (gpm*psi) / (1714*efficiency). In order for it to have an input hp of 16, a gpm of 28, and a psi of 900, it must have an efficiency of 92%. Isn't that really high?

      Also, what is the gpm when it is running at 3000 psi?
    • That's pretty accurate for a gear pump.

      The PSI won't affect the GPM, only RPM's will.
  • From kenneth at 4/13/16 10:40 AM
    • I have a Subaru Robin gear reduction motor. It makes 10hp at the engines 3600 RPM but the gear reduction drops the PTO speed to 1800 (torque is approximately double) would this motor be able to turn this pump and how many GPM would I approximately get turning it at 1800 only?
    • Half the rotations = half the flow.
