What is a 2 stage hydraulic pump?

How Does a Two Stage Hydraulic Pump Work - Target Hydraulics

A two-stage hydraulic pump combines a large-displacement, low-pressure pump and a smaller-displacement, high-pressure pump into a single unit to improve efficiency and speed. It provides high flow for rapid movement during the initial phase of an operation and then switches to high pressure to perform the main work, such as splitting wood or compacting trash. This design allows for a powerful output without requiring a larger, more powerful motor.

This video demonstrates how a two-stage pump works on a log splitter:

Stage 1 (High Volume/Low Pressure):
The pump's two pumps work together to move fluid quickly, creating a high flow rate at a low pressure. This is the initial, fast-moving phase of the work cycle, as seen when a log splitter's wedge first makes contact with the log.
Switching to Stage 2 (High Pressure):
Once the pump reaches a predetermined pressure threshold, an internal valve redirects the flow. The large, low-pressure pump is unloaded (its flow is returned to the reservoir), and only the small, high-pressure pump continues to deliver fluid to the system.
Stage 2 (High Pressure/Low Volume):
The smaller, high-pressure pump provides the force needed for the heavy work, like splitting the log. Although the flow rate is lower, the increased pressure is necessary to complete the task.
