FD3000 / 3100 Function
The main function of the PERMCO FD3000 / 3100 Flow Divider, is to accept flow then divide it equally or unequally. Alternatively it can combine flow in the return direction and distribute pressure based on your requirements.
The main benefits of using a PERMCO flow divider in your hydraulic system is to:
- Simplify circuitry.
- Increase life of components.
The above will achieve a reduction in costs.
Basic Sizing Requirements
The most efficient gear widths are 1 or larger.
The most efficient speed of the PERMCO flow dividers is between 700 - 1400 RPM.
Units with ALL gear widths of 1/2 and 3/4should be avoided.
EXAMPLES: Units with 1/2 gears would work best with another section of a least 1-1/2
Units with 3/4 gears would work best with another section of a least 1-1/4
In three section units or larger, it is good practice to position the inlet port nearest the largest gear section. It is also recommended that the largest gear section be placed in the centre of the unit.
For applications where speeds are below 500 RPM or above 1400 RPM, and/or where pressure across the unit may exceed 2000 PSI (138 Bar) for the 3000 series / 2500 PSI (172 BAR) for the 3100 series, please CONTACT US to discuss further.
How to Select Your Flow Divider
To select your PERMCO flow divider, this procedure should be followed:
For equal flow division:
Select a gear width greater than one (1) inch from the charts keeping the speed between about 700 RPM and 1400 RPM.
For unequal flow division use the following procedure:
- Determine the outlet flow required for each leg of the hydraulic circuit.
- Use charts below to select a series and gear width for the leg with the greatest flow (keeping gear widths greater than one (1) inch).
- Move straight up the chart to select the other gear widths by choosing gear widths with the closest flow at the same RPM.
- Check the actual flow for each section to determine if acceptable using the following formula.
GEAR WIDTH / (TOTAL GEAR WIDTH) X TOTAL
FLOW FLOW FOR SECTION - If the flows are not acceptable, repeat from step (2) by choosing a different gear width or moving to a chart in another series.

FAQ's of Gear Flow Dividers FD3000 3100 Series:
Q: How do I install the FD3000 3100 Series Gear Flow Dividers?
A: The FD3000 3100 Series is designed with standard mounting holes and threaded hydraulic ports for straightforward installation. Simply secure the unit using compatible mounting hardware and connect the inlet and outlet ports according to your hydraulic circuit's requirements.
Q: What applications are suitable for these flow dividers?
A: These gear flow dividers are ideal for hydraulic circuits where accurate flow division or combining is necessary. They're commonly used in industrial machinery, mobile equipment, and systems demanding synchronization of multiple actuators or balanced flow distribution.
Q: When should I choose a 2, 3, or 4-section model?
A: Select the number of sections based on the number of flow paths or circuits you need to divide or combine. A 2-section divider suits dual-circuit systems, while 3- and 4-section variants are chosen for more complex circuits requiring multiple synchronized outputs.
Q: Where can these flow dividers be used with respect to environment and temperature?
A: With an operational temperature range of -20C to +80C and corrosion-resistant finish, these units perform reliably both outdoors and indoors, even in challenging industrial or mobile environments where temperature fluctuations and exposure are common.
Q: What process ensures the divider's accuracy in flow?
A: The FD3000 3100 Series utilizes precisely machined parallel steel gears within a cast iron body, delivering dependable, accurate flow division to within 1.5% per section. This ensures each circuit receives nearly identical flow rates as per design.
Q: What are the main benefits of using the FD3000 3100 Series?
A: Key benefits include highly accurate flow division, robust construction for high-pressure applications, easy installation, modularity, low noise, and compatibility with both manual and automated controls-making them versatile solutions for demanding hydraulic systems.
Q: How should the units be maintained for optimal performance?
A: Periodic inspection of seals, connections, and mounting bolts is advised. Ensure the use of clean hydraulic oil and monitor for unusual noise or leakage. The corrosion-resistant finish minimizes maintenance needs, but prompt attention to wear ensures long-term reliability.
