2CB-E13/1.8 Log Splitter Hydraulic Pump 2 Stage Log Splitter Pumps

The 2CB-E13/1.8 Log Splitter Hydraulic Pump is a two-stage hydraulic gear pump designed for efficient log splitting and other high-pressure applications. With a 13 GPM (gallons per minute) flow rate, it combines a large displacement low-pressure pump and a small displacement high-pressure pump, automatically switching between stages to optimize performance. It delivers up to 3,000 PSI, making it ideal for 5 to 35-ton log splitters, machine tools, and trash compactors.

The hydraulic log splitter pump features a 1/2" shaft diameter, 1.5" shaft length, and a 1/2" NPT outlet port requiring a male NPT fitting to prevent damage. Constructed with a durable aluminum or cast iron housing, it ensures reliability and resistance to impact and rust. Its 4-hole bolt-on design allows easy installation, and it operates at up to 3,600 RPM, providing fast cycle times and compatibility with brands like RuggedMade and Champion.

How Does a 2-Stage Hydraulic Log Splitter Pump Work?

A 2-stage hydraulic log splitter pump is a specialized gear pump designed to optimize the performance of log splitters by balancing speed and power. It operates in two distinct stages—high-flow/low-pressure and low-flow/high-pressure—automatically switching based on the resistance encountered. This dual-stage mechanism makes it highly efficient for splitting logs of varying hardness.

In the first stage, the hydraulic log splitter pump operates in high-flow mode, typically delivering up to 13 GPM (gallons per minute) at lower pressure (around 650 PSI). This stage uses a larger displacement gear set to move the hydraulic ram quickly toward the log, minimizing cycle time when little force is needed. The pump draws hydraulic fluid from the reservoir through a 1" barb inlet port and pushes it through a 1/2" NPT outlet port into the hydraulic cylinder, extending the ram rapidly.

When the ram encounters significant resistance, such as a tough knot in the log, the log splitter hydraulic pump automatically switches to the second stage. This high-pressure mode reduces flow rate (to around 3-4 GPM) but increases pressure up to 3,000 PSI, using a smaller displacement gear set to generate the force needed to split the log. The transition is managed by an unloader valve, which redirects fluid flow based on pressure thresholds, ensuring seamless operation without manual intervention.
