CONCENTRIC

CONCENTRIC is a brand historically associated with hydraulic flow dividers and related fluid-power components. The product line available through 3G Electric focuses on rotary gear-type flow dividers, which are used to split a single hydraulic pump flow into two or more separate circuits. These dividers are typically applied where synchronized movement of cylinders or motors is required, such as in mobile equipment, industrial machinery, and hydraulic power units. The rotary gear-type design uses meshing gears to divide flow proportionally, and the units are configured with SAE O-Ring Boss ports for leak-resistant connections. Available models cover a range of flow capacities, from low-flow units rated at 2.4 to 5 gpm with #8 SAE O-Ring Boss ports, through mid-range 5 to 10 gpm units with #10 SAE O-Ring Boss ports, up to higher-capacity 10 to 20 gpm units with #16 inlet and #10 outlet ports. Each divider is identified by a manufacturer part number, such as 1020075, 1020076, or 1100042, which allows for precise cross-referencing. The gear-type construction is intended for continuous duty in hydraulic systems, and the port sizes are standardized to simplify integration with existing manifolds and hose assemblies. 3G Electric supplies these CONCENTRIC flow dividers as individual SKUs, with multiple part numbers available for different flow ranges and port configurations. The product data includes flow range, port type, and manufacturer part number, enabling technical buyers to match the divider to the system's required flow and connection size. For plant engineers and maintenance managers, the key selection criteria are the total pump flow, the number of circuits to be supplied, and the desired division ratio—equal or proportional. The rotary gear design inherently provides a fixed ratio based on gear geometry, so the flow split is determined at the time of manufacture. This makes it important to specify the correct model for the application. 3G Electric's catalog provides the necessary specifications to identify the appropriate CONCENTRIC flow divider for a given hydraulic circuit. The brand's flow dividers are used in applications where independent circuits must operate in coordination, such as dual-cylinder lifting, steering systems, and conveyor drives. Because the dividers are positive-displacement devices, they can also act as pressure intensifiers in certain configurations, although the primary function is flow division. The SAE O-Ring Boss ports comply with standard SAE J1926, which is common in North American and global hydraulic systems. The flow ranges listed—2.4 to 5 gpm, 5 to 10 gpm, and 10 to 20 gpm—cover many small to medium hydraulic power applications. 3G Electric supports the CONCENTRIC line by stocking multiple SKUs and providing logistics coordination for global delivery. Technical documentation, including part numbers and port specifications, is available to assist with selection and replacement. For procurement specialists, the availability of discrete part numbers simplifies inventory management and reordering. The brand's focus on flow dividers means that the product family is narrow but deep, with variations primarily in flow capacity and port size. This specialization allows for straightforward specification: determine the required flow per circuit, select the port size that matches the system's plumbing, and choose the corresponding part number. 3G Electric's role is to make these components accessible with clear specifications and reliable supply.

Frequently asked questions

Common questions about CONCENTRIC from 3G Electric.

What is the flow range of the CONCENTRIC rotary gear-type flow divider with #10 SAE O-Ring Boss ports?

The CONCENTRIC rotary gear-type flow divider with #10 SAE O-Ring Boss ports, manufacturer part number 1020076, has a flow range of 5 gpm to 10 gpm. This model is designed to split a single pump flow into multiple circuits for synchronized actuator operation. The #10 SAE O-Ring Boss port size corresponds to a 7/8-14 UNF thread, which is common in hydraulic systems. When selecting this divider, ensure the total system flow falls within the 5 to 10 gpm range for proper division. The unit is identified by SKU 4F661 in 3G Electric's catalog.

How do I choose between CONCENTRIC flow dividers with different port sizes?

Port size selection depends on the flow rate and the existing plumbing in your hydraulic system. CONCENTRIC offers dividers with #8, #10, and #16 SAE O-Ring Boss ports. The #8 port model (MPN 1020075) is rated for 2.4 to 5 gpm, the #10 port model (MPN 1020076) for 5 to 10 gpm, and the #16 inlet / #10 outlet model (MPN 1100042) for 10 to 20 gpm. Match the port size to your hose or manifold connections to avoid adapters. Also consider the required flow per circuit; the divider's gear ratio determines the split, so the total flow must be within the rated range.

What is the function of a CONCENTRIC rotary gear-type flow divider in a hydraulic system?

A CONCENTRIC rotary gear-type flow divider splits a single hydraulic pump flow into two or more separate streams. This allows synchronized operation of multiple cylinders or motors. The gear-type design uses meshing gears to divide the flow proportionally, either equally or in a fixed ratio determined by gear geometry. It is a positive-displacement device, so the division ratio remains consistent regardless of pressure variations, provided the flow is within the rated range. Typical applications include dual-cylinder lifting, steering circuits, and conveyor drives where coordinated movement is required.

What are the port specifications for the CONCENTRIC flow divider with MPN 1100042?

The CONCENTRIC flow divider with manufacturer part number 1100042 has a #16 SAE O-Ring Boss inlet and a #10 SAE O-Ring Boss outlet. It is rated for flow rates from 10 gpm to 20 gpm. The #16 SAE O-Ring Boss port uses a 1-5/16-12 UNF thread, while the #10 port uses a 7/8-14 UNF thread. This configuration allows a larger inlet flow to be divided into smaller outlet circuits. The unit is available as SKU 4F662 in 3G Electric's catalog. Ensure the outlet circuit components are rated for the divided flow and pressure.

Can CONCENTRIC flow dividers be used with different hydraulic fluids?

CONCENTRIC rotary gear-type flow dividers are intended for use with standard hydraulic fluids, such as mineral-based hydraulic oils. The compatibility depends on the seals and materials of construction, which are not specified in the available product data. For applications involving fire-resistant fluids, biodegradable fluids, or high-water-content fluids, consult the manufacturer's technical documentation to confirm compatibility. The SAE O-Ring Boss ports use standard O-rings, which may need to be replaced with material suitable for the specific fluid. Always verify fluid compatibility before installation to avoid seal degradation and leakage.

What is the difference between equal and proportional division in CONCENTRIC flow dividers?

Equal division means the flow is split into two or more streams of identical volume, while proportional division splits the flow according to a fixed ratio, such as 60/40. The division ratio in a CONCENTRIC rotary gear-type flow divider is determined by the gear geometry, so it is fixed at the time of manufacture. The product data for the available SKUs does not specify the division ratio, so it is important to confirm whether the model provides equal or proportional division for your application. If the ratio is critical, contact the manufacturer or a distributor with the part number to obtain the specific division characteristics.
