Hydraulic Central manifolds for compact and modular system design
Hydronit hydraulic central manifolds are designed to simplify the development of compact hydraulic power units for industrial, mobile and marine applications. Their modular architecture helps integrate valves and components efficiently, reduce overall dimensions and support a wide range of configurations.
Built to combine flexibility, reliability and ease of assembly, these solutions are ideal for OEMs, distributors and system integrators looking for a compact manifold platform that can adapt to different hydraulic requirements.
A range of hydraulic manifolds for different application needs
Hydronit offers different central manifold solutions to support a wide variety of hydraulic layouts, from conventional compact power packs to more advanced smart systems with embedded electronics and sensor integration. Depending on the application, the range can meet different needs in terms of flexibility, control logic and overall system integration.
MICRO CENTRAL MANIFOLD
The Micro Central Manifold is designed to create extremely small hydraulic power units for industrial, mobile and marine applications. Made of die-cast aluminium, it combines reduced dimensions with a high level of integration, making it a flexible solution where space is limited but performance and configuration options remain essential.
It can integrate up to seven devices inside a single manifold and also be combined with additional manifold blocks for cartridge valves or external NG6 valves. Unified interfaces for hose fittings, tanks and motors help simplify system design and assembly, while compatibility with AC, DC and BLCD motors and different pump rotations offer greater application flexibility.
The Micro Central Manifold supports clockwise, counterclockwise or bidirectional gear pumps, with a maximum flow of 6 l/min and motor power up to 3 kW, providing a compact and versatile base for extra small hydraulic power units.
Yes. We can supply either fully assembled and tested power packs or kits of loose components which can be kept in stock by our worldwide distributors and easily assembled to satisfy local market demand quickly and effectively. Central manifolds and other components are quality tested even when supplied as loose parts.
MB type is the most widely applied for single acting or double acting circuits. M4 execution is recommended for compact and cost effective double acting circuits with a single cylinder while MR is for bidirectional pump and may integrate double relief valve, double pilot operated check valves and also an extra pilot operated check valve to ensure that differential cylinder circuits function properly (this extra valve discharges excess return flow from the piston side of the cylinder).
UNIVERSAL CENTRAL MANIFOLDS for PPC
Hydronit Universal Central Manifolds for PPC are designed for compact hydraulic power packs used in industrial, mobile and marine applications. Made of die-cast aluminium, they offer a modular and highly integrated solution that helps simplify the configuration of hydraulic units while maintaining flexibility across different system layouts.
These manifolds are developed to support a wide range of components, with unified interfaces for motors, tanks and hose fittings, making assembly and integration easier. Their architecture also allows different valve and pump configurations, helping manufacturers and system integrators create compact hydraulic systems that are efficient, adaptable and easier to standardize.
Depending on the execution, the PPC range can support higher flow and power rating than Micro solutions, making it suitable for applications that require a more versatile and structured manifold platform within a compact power unit.
Yes. We can supply either fully assembled and tested power packs or kits of loose components which can be kept in stock by our worldwide distributors and easily assembled to satisfy local market demand quickly and effectively. Central manifolds and other components are quality tested even when supplied as loose parts.
No. All valves are screw-in type in a single piece construction (no loose nuts, washers, springs; nothing difficult to assemble or fall apart). The components can be easily assembled with simple hand tools and hexagon or Allen wrenches.
UA type is the most widely applied for single acting or double acting circuits. UB is the real «Universal» central manifold since, in addition to UA type features, there are two extra lateral cavities to mount, for example, an integrated emergency hand pump and an externally adjustable flow control. U4 is recommended for compact and cost effective double acting circuits with a single cylinder. SR type is used with bidirectional pumps and can integrate P.O. check valves and differential cylinder vent valve (SRD version), SB3 is for circuits with 3-way hydraulic operated valve for automatic venting when the electric motor is off, SB is applied for single acting or double acting circuits with alternative components location than the UB and additional features. S4 is recommended for driving up to two double acting cylinders with integrated cartridge valves. SX* are for SPU. Further executions are available on request.
SMART CENTRAL MANIFOLDS for PPC
The Smart Central Manifolds SX1 & SX2 are developed for applications that require more advanced hydraulic control and closer integration with electronic management systems. Designed for Smart hydraulic Power Units, they provide a compact manifold solution for projects where control accuracy, monitoring and functional integration are key.
Their design supports advanced functions such as proportional flow control, proportional pressure control and optional load sensing, making them particularly suitable for more sophisticated hydraulic applications. Integration with dedicated electronic systems and embedded sensors allows these manifolds to support a more intelligent and responsive hydraulic architecture.
The SX1 and SX2 range is an ideal choice for manufacturers looking for a manifold platform that combines compactness, hydraulic performance and smart control potential in a single solution.
The Smart Central Manifolds are available also for conventional hydraulic units in the following configurations: SB, for single and double acting circuits, SB3, with embedded 3-way valve, SR* for reversible circuits with bidirectional gear pumps and integrated pilot operated check valves plus differential area discharge valve, S4 for two double acting integrated 4/3 solenoid valves.
CENTRAL FLANGES for DC ELECTROPUMPS
Hydronit Central Flanges for Electropumps are designed to provide a reliable connection between the electric motor and the hydraulic pump assembly. They play an important role in ensuring proper integration and a compact overall system design.
These solutions are developed to support different electropump configurations and help satisfy a variety of applications. Their design contributes to a more organized and functional assembly, while maintaining the flexibility required for different technical layouts.
Central flanges are therefore a key component for manufacturers and integrators looking for a practical and reliable solution to optimize the structure and integration of compact electropumps.
Yes. We can supply either fully assembled and tested electropumps or kits of loose components which can be kept in stock by our worldwide distributors and easily assembled to satisfy local market demand quickly and effectively.
Depending on the motor frame you have multiple options:
- for frame 80 DC motors (power up to 1200W) you have only the choice of group 0 pumps. these are the same used in PPM and PPC power packs (front flange P port and rear flange suction port). Lateral ports group 0 KL series pumps can be fit too.
- for frame 114 and 125 DC motors (1600W up to 4000W), the same central flange can accomodate standard power pack pumps, either group 0 (with an adapter) or group 1, with the front flange P port, connected to the lateral 1/4 BSPP exit port. As alternative, the classical group 1 KL series pumps with lateral ports are available. These can be fitted with P and T ports which can be rotated 180°, when configuring the power pack, in order to allow ports positioning flexibility.
- for frame 151 (DC motors 2500W, 3000W and 4000W), a standard B14 bell housing and coupling is used. Only KL lateral ports pumps are usable.
