Introduction to Hydraulic Flow and LPM
When using heavy equipment like excavators or skid steers, hydraulic attachments require a certain amount of hydraulic flow (measured in Liters Per Minute, or LPM) to operate effectively. Understanding how to determine the required LPM for different attachments is crucial for ensuring they operate at peak efficiency and to avoid damage to either the attachment or the machine’s hydraulic system.
What is LPM and Why is it Important?
LPM (Liters Per Minute) measures the volume of hydraulic fluid that flows through the system per minute. Each hydraulic attachment—whether it’s a hammer, shear, auger, or grapple—has a specific LPM requirement. Ensuring that the hydraulic system on your equipment can meet the LPM demand of the attachment is vital. Too low a flow rate may lead to underperformance or failure of the attachment, while too high a flow rate can cause overheating or even damage to the hydraulic components.
Determining the Required LPM for Hydraulic Attachments
To figure out the appropriate LPM for hydraulic attachments, several steps need to be followed:
To prevent hydraulic issues, it’s important to match the flow rate of the hydraulic attachment with the machine’s capabilities. For example, if you are using a high-flow attachment such as a hydraulic breaker or high-flow auger, you will need a machine with a high-flow hydraulic system. Conversely, standard-flow attachments like grapples or basic shears typically require less hydraulic flow.
Using an attachment that exceeds the machine’s hydraulic flow capacity can result in inefficient operation, overheating, and damage to both the machine and attachment. Therefore, it’s critical to ensure that both the attachment and machine are compatible in terms of hydraulic flow rate.
Troubleshooting Flow Issues
If you are experiencing performance issues with a hydraulic attachment, here are a few things to check:
Determining the correct LPM for attaching hydraulic attachments is essential for both performance and longevity. By understanding the flow requirements of your attachments, matching them to your machine’s hydraulic capabilities, and adjusting the flow rate when needed, you can ensure that your equipment runs efficiently and avoid unnecessary maintenance costs. Regularly checking your hydraulic system and staying informed about both your machine’s and attachment’s specifications will help you get the most out of your hydraulic attachments.

Determining the Required LPM for Hydraulic Attachments
To figure out the appropriate LPM for hydraulic attachments, several steps need to be followed:
- Check the Attachment Specifications: Most hydraulic attachments come with manufacturer-provided specifications, which include the required LPM for optimal performance. This information can usually be found in the user manual or datasheet for the attachment.
- Machine Flow Rate: Understand the flow rate of your machine. Different machines come with different flow capacities, and knowing the LPM your equipment can handle is essential to match it with the attachment’s needs. Equipment manufacturers typically list the maximum flow rate of their machines in the user manual or technical specifications.
- Adjustable Flow Settings: Some machines, particularly skid steers and mini-excavators, come with adjustable flow settings. These systems allow operators to adjust the hydraulic flow to suit the needs of various attachments. If your machine has an adjustable flow rate, you can set it to match the attachment’s requirements.
- Flow Dividers and Flow Regulators: If the machine’s hydraulic system provides more flow than the attachment can handle, a flow divider or regulator can be used to reduce the flow to the desired level. These components ensure that the right amount of hydraulic fluid reaches the attachment, preventing overpressure.
To prevent hydraulic issues, it’s important to match the flow rate of the hydraulic attachment with the machine’s capabilities. For example, if you are using a high-flow attachment such as a hydraulic breaker or high-flow auger, you will need a machine with a high-flow hydraulic system.

Troubleshooting Flow Issues
If you are experiencing performance issues with a hydraulic attachment, here are a few things to check:
- Underperformance: If the attachment is not working at full capacity, it may not be receiving enough hydraulic flow. Check both the machine's flow capacity and the attachment’s requirements to make sure they match.
- Excessive Heat: If the hydraulic system or the attachment is overheating, it could indicate that the flow rate is too high for the system or attachment. A flow regulator may be required to reduce the flow to the necessary level.
- Leaking or Damaged Hoses: Leaks in the hydraulic lines can cause a loss of pressure, affecting the attachment’s performance. Inspect the hydraulic hoses for any signs of wear or damage.
Determining the correct LPM for attaching hydraulic attachments is essential for both performance and longevity. By understanding the flow requirements of your attachments, matching them to your machine’s hydraulic capabilities, and adjusting the flow rate when needed, you can ensure that your equipment runs efficiently and avoid unnecessary maintenance costs. Regularly checking your hydraulic system and staying informed about both your machine’s and attachment’s specifications will help you get the most out of your hydraulic attachments.
