Hydraulic Log Splitter Pump Kit, 16 GPM 2-Stage, Valve

Hydraulic log splitter pump kit delivers fast cycle times and strong splitting force with a 2-stage hydraulic gear pump designed for small-engine mounting. The 16 GPM flow supports quick return speeds, while the high-pressure stage boosts power when the wedge meets resistance. Standard port sizes help simplify hookups, and the included directional control valve gives you precise control for builds, repairs, and upgrades.

• Delivers 2-stage performance: high flow for speed, high pressure for tough logs and consistent splitting power


• Fits small-engine log splitters with a 1/2" shaft and 2.83" bolt circle (4 holes, 2" spacing)


• Includes a hydraulic directional control valve plus wrench, flat key, and thread seal tape for install support


• Supports quieter work with operating noise below 75 dB to reduce distraction in the shop or yard


• Powers more than splitters—use for presses, machine tools, and snowplow-style hydraulic systems

Built for dependable sealing and stable operation, this pump kit uses common inlet/outlet sizing to reduce guesswork during replacement or DIY assembly. Match it to an engine rated at least 8 HP and use a suction-side filter of 150 microns or finer for cleaner fluid and smoother performance. Whether you’re refreshing a worn pump or building a splitter from the ground up, this kit keeps your hydraulic system responsive—grab yours today.
