PLD10/4/CS-GD/2-GC/VPEF Casappa Flow Divider 250bar

Product Overview

The PLD10/4/CS-GD/2-GC/VPEF is a 4-section gear-type flow divider (synchronous分流马达) from the Casappa POLARIS series (Group 10). Built on the Group 10 standard mounting platform, this product features a geometric displacement of 4 cm³/rev per section.

Engineered with a high-strength cast iron housing and precision gear metering elements, this flow divider serves three critical functions: flow equalizer, flow divider, and pressure booster. As a core component of hydraulic synchronization systems, it accurately divides a single input flow into multiple output flows at fixed ratios, enabling precise synchronous actuation of multiple hydraulic actuators. Synchronization accuracy reaches 1.5% – 2.5%.

Every unit is manufactured to original equipment specifications, ensuring 100% drop-in interchangeability with genuine Casappa PLD10 series flow dividers without any system modifications. Each unit undergoes rigorous 100% simulated duty-cycle testing to validate splitting accuracy and pressure-flow performance curves.

Key Technical Advantages

1. High-Precision Synchronous Control

Based on precision gear metering principles, the flow divider achieves 1.5% – 2.5% splitting accuracy, ensuring precise synchronous motion of multiple actuators (hydraulic cylinders, motors) and eliminating asynchronous issues caused by uneven flow distribution.

2. Three-in-One Functionality

A single product delivers flow equalization, flow division, and pressure boosting capabilities. It can serve as an equal-flow divider for synchronous multi-actuator systems or as a proportional flow divider for circuits with differentiated flow requirements.

3. Modular Design for Maximum Flexibility

Built on the Group 10 platform, the unit supports 2–12 section combinations. This model is a standard 4-section configuration. Users can assemble different displacement sections within the same series to accommodate cylinders of varying sizes in synchronous applications.

4. Cast Iron Housing for High-Pressure Durability

The high-strength cast iron housing provides superior structural rigidity and pressure containment compared to aluminum alternatives, making it ideal for demanding medium-to-high pressure (280–320 bar peak) industrial hydraulic systems requiring long-term continuous operation.

5. Integrated Section Relief Valves for Overload Protection (Optional)

This model can be configured with VPEF section relief valves, providing independent overload protection for each output circuit. When one circuit experiences excessive load, the corresponding relief valve automatically opens to unload pressure, preventing system damage without affecting other circuits.

6. 100% Simulated Duty-Cycle Testing

Every unit is 100% tested on dedicated hydraulic test benches under simulated real-world operating conditions—validating splitting accuracy and pressure-flow characteristics at rated pressure (250 bar) and peak pressure—ensuring zero-defect, plug-and-play performance upon installation.

Application Areas

• Multi-Cylinder Synchronous Hydraulic Systems: Equipment requiring precise synchronous lifting, pushing, or clamping of multiple hydraulic cylinders

• Construction Equipment: Concrete pump outrigger synchronization, crane multi-winch synchronous drives

• Agricultural Machinery: Large implement multi-point hitch synchronization, sprayer multi-nozzle flow distribution

• Industrial Equipment: Hydraulic press multi-cylinder synchronized pressing systems, injection molding machine multi-circuit synchronous actuation

• Material Handling: Lift platform multi-point synchronous lifting, AGV multi-wheel synchronous drives

Expert Maintenance Tips

1. Fluid Cleanliness Control

Gear-type flow dividers are highly sensitive to fluid contamination. Maintain system fluid cleanliness to ISO 4406 19/17/14 or better. Install a ≤10 μm absolute filtration filter upstream of the inlet port to prevent particle contamination from affecting gear metering elements and splitting accuracy.

2. Monitor Pressure Differential Between Sections

The maximum allowable pressure differential between sections for this model is 200 bar. Closely monitor load pressure differentials across all output circuits during operation—do not exceed this limit. Excessive pressure differential will significantly degrade splitting accuracy; check for load imbalances across circuits.

3. First-Start Priming Procedure

Before initial startup, thoroughly bleed air through each outlet port or drain port. Perform 2–3 low-speed jog starts under no-load conditions until oil fills all sections without air bubbles, then connect load circuits for full operation.

4. Periodic Splitting Accuracy Verification

Verify flow consistency across all output circuits every 2,000 operating hours or at least annually. If splitting accuracy exceeds acceptable limits, inspect gear metering elements for wear and replace service kits as necessary.

5. Relief Valve Pressure Settings

The integrated VPEF section relief valves are factory-preset to customer-specified pressures. Do not adjust relief valve settings in the field. Any pressure setting changes must be performed by qualified technicians using specialized test equipment.
