Hydraulic Cast Iron Gear Flow Divider

This cast-iron gear-type synchronous flow divider (hydraulic flow divider) consists of multiple gear motor units rigidly connected on a common shaft. It achieves forced mechanical synchronization-unaffected by pressure differentials at the outlets-by splitting a single inlet flow into multiple streams of equal or proportional output, thereby driving multiple hydraulic cylinders or motors to operate in perfect synchronization (e.g., simultaneous lifting, extending, or retracting).

The unit features a high-strength cast-iron housing that offers exceptional rigidity and resistance to vibration and impact, making it suitable for demanding high-pressure, heavy-load applications. It supports integrated relief valves and make-up check valves, as well as multi-section configurations (ranging from 2 to 12 sections) for either equal or proportional flow division. It is widely used in hydraulic synchronization systems for various types of heavy-duty construction machinery

Features

1. Heavy-duty cast iron housing: High-strength housing offers excellent impact and vibration resistance and reduced noise during low-speed operation; compatible with various hydraulic fluids (such as mineral oil and water-glycol) to meet the rigorous demands of mining, marine, and metallurgical applications-outperforming aluminum alloy flow dividers.
2. Rigid mechanical synchronization: Gear shafts are rigidly linked, achieving synchronization accuracy of ±1.5% to ±2.5%; robust resistance to unbalanced loads ensures effective synchronization even when loads across multiple cylinders vary.
3. Modular multi-section configuration: Flexible combination of 2 to 12 sections; customizable with unequal displacement units for non-proportional flow distribution; available with flange or threaded ports.
4. Integrated protection valve options: Each section can be equipped with relief valves and make-up check valves to prevent cylinder overload and cavitation, thereby protecting motors and the hydraulic system.
5. High pressure rating: Rated pressure up to 280 bar; compact design, resistant to fluid contamination, and easy to maintain.
