The GL9RD02 series is a high-precision, group-2 rotary gear-type hydraulic flow divider composed of multiple medium-displacement gear sections that are mechanically keyed onto a common internal shaft. This positive-displacement design splits a single primary pump inlet stream into multiple independent output flows. By forcing all internal gear segments to rotate at the exact same speed, it ensures robust fluid synchronization among multiple downstream cylinders or motors, making it highly effective even under asymmetric or shifting workload resistances.
High-Torque Positive Displacement: Operates via mechanically linked internal gears driven entirely by the pressure of the fluid. The flow splitting accuracy is governed strictly by the geometry of the teeth, making it highly immune to fluctuations in oil viscosity, temperature, or load imbalances.
Heavy-Duty Structural Frame: Typically constructed with a high-tensile cast iron housing (or reinforced alloy) to withstand the massive structural stresses and internal separating forces generated during high-flow, high-pressure operation.
Pressure Intensification Utility: Acts as a localized hydraulic pressure booster. If one downstream line experiences zero resistance, its mechanical energy is transmitted through the central shaft to help the heavily loaded section, raising its output pressure beyond the primary pump's relief valve threshold.
Integrated Safety & Re-phasing Valves: Can be configured with integrated end-of-stroke re-phasing relief valves and anti-cavitation check valves. This automatically bleeds air, re-aligns cylinders when they bottom out, and protects against vacuum damage.
| Parameter | Range / Value | Metric & US Units | Notes |
|---|---|---|---|
| Displacement per Section | 4.0 ~ 26.0 | cc/rev (cm³/rev) | Group-2 medium displacement size, suitable for medium & large flow hydraulic synchronization systems. |
| Flow Capacity per Section | 10 ~ 80 | L/min (approx. 2.6 ~ 21 US gpm) | Allowable flow rate for single input/output channel. Large port design effectively reduces flow resistance. |
| Max. Continuous Pressure | 240 | bar (approx. 3480 psi) | Suitable for continuous high-pressure working conditions, rigid valve body resists deformation. |
| Max. Intermittent Pressure | 280 | bar (approx. 4060 psi) | Short-term peak pressure allowed under heavy-load startup, shifting impact or shock load. |
| Synchronization Accuracy | ±1.5% ~ ±2.0% | Percentage error range | Rigid mechanical shaft synchronization, barely affected by uneven load or oil temperature fluctuation. |
| Number of Sections | 2 ~ 4 | Sections / Channels | Common configurations: 2-section or 4-section. Sectional structure supports multi-section customization. |
| Typical Pressure Drop | 12 ~ 18 | bar (approx. 174 ~ 260 psi) | Self energy loss generated to drive gear rotation, this heat source shall be considered in system design. |
| Fluid Temp. Range | -20 ~ 80 | °C (-4°F to 176°F) | Operating range with standard NBR rubber seals. Fluororubber seals are required for high-temperature systems. |
