Hydraulic Log Splitter Gear Pump: 2-Stage, 11 GPM

In stock

This 2-stage hydraulic pump combines a large displacement low-pressure pump and a small displacement high-pressure pump. It is ideal for use with log splitters, machine tools, trash compactors, and other applications.

  • 11 GPM flow rate
  • 3,000 pressure rating
  • 1/2" shaft diameter
  • 1.375" shaft length
  • Perfect for use on 5 to 35-ton log splitters

NOTE: The outlet port for this pump requires a male NPT fitting. To avoid damaging the pump, do not use a straight-thread, O-ring style fitting.

If you also need a hydraulic valve, couplings, or mounting bracket, see Related Products below.

The Ideal Hydraulic Pump for Log Splitters

This 2-Stage pump fits a wide variety of log splitters and outdoor power equipment and works in both horizontal and vertical orientations. The included inlet nipple requires a 1" inner diameter suction hose. 

Rated for up to 3,000 PSI at 3,600 RPM, this pump can power log splitters from 5 to 35 tons, depending on the inner diameter of the hydraulic cylinder. It features a fast cycle time by moving quickly when unloaded. It automatically shifts to low-flow/high-pressure mode at 500 PSI.

Be sure to use AW-32 10-Weight (ISO 32) or AW-46 20-Weight (ISO 46) light hydraulic fluid or Dexron III automatic transmission fluid. This pump is not designed for use with “universal” or "tractor" transmission oil, such as "303". The use of incorrect fluid may damage the pump and void the warranty.

Make sure the hydraulic fluid reservoir is not below the pump to ensure a sufficient flow of fluid to the pump. Suction-side filtration should be no finer than 150 microns. The use of a 10-25 micron filter on the suction side of the pump is too restrictive and will cause failure.

We recommend using an L-style jaw coupling to connect the pump to an engine. Couplings and mounting brackets are available. You should use at least a 5hp 163cc engine to maintain 3,600 RPM under load.

The mounting flange on this pump has a 4-bolt, 2 inches on center, mounting pattern. The bolt circle is 2.85" and the bolt holes are M8 (.344").
