Hydraulic Systems Explored: Purpose and Extensive Usage Across Various Fields

In India, the landscape of hydraulic systems is evolving, with the emergence of Make-in-India valve clusters and a growing pump market valued at US $ 859 million in 2024. This development is driven by sectors such as construction equipment, urban metro expansion, defense offsets, and agri-mechanisation.

However, the techno-economic barriers limiting the efficiency and indigenization of hydraulic systems in India are significant. These include high costs of advanced components, reliance on imported high-precision parts, limited technological know-how for integrating digital controls, and challenges in adapting designs for local industrial conditions.

To address these barriers, focused efforts on localization, digitization, and decarbonization are required.

Localization

Indigenous manufacturing for critical components such as high-pressure filters, valves, and sensors is crucial for improving reliability and safety in hydraulic systems, particularly in defence and aerospace sectors. This can be achieved by promoting R&D collaborations between industry and academic institutions to adapt designs for Indian operating conditions and resource availability. Additionally, supporting MSMEs (Micro, Small, and Medium Enterprises) to enter the hydraulic component supply chain is essential.

Digitization

Integrating digital sensors for real-time flow, pressure, temperature, and contamination monitoring can enhance system reliability and predictive maintenance. Deploying advanced data logging and automated control systems can optimize hydraulic operations and reduce downtime. Using digital twins and simulation tools during design and testing can improve product performance adaptability.

Decarbonization

Shifting to energy-efficient hydraulic power units with low noise and reduced power consumption is vital for sustainable development in India. Incorporating renewable energy sources or hybrid systems to power hydraulic operations where feasible is another step towards decarbonization. Using eco-friendly hydraulic fluids and improving filtration technologies can also reduce environmental impact.

By combining these approaches, India can improve the cost-effectiveness, performance, and sustainability of hydraulic systems while boosting indigenous technology development and manufacturing capabilities.

Notable initiatives in this direction include the establishment of the National Fluid-Power Centre of Excellence (NFPCoE) at IIT-Roorkee, which leverages the IAHR 2024 network, co-locates precision test rigs, and a TRL-7 pilot line for servo-valves.

The Defence Corridor Localisation Targets under the Defence Production & Export Promotion Policy 2020 reserves certain hydraulic sub-systems for at least 50 percent domestic value-addition. The Green Construction Catalyst Fund allocates carbon credit revenues to subsidise high-efficiency hydraulic excavators in river-front rejuvenation and Smart City projects.

The tech-sector is also responding to the call for sustainability. For instance, the Skill Super-50 Hydraulic Technicians initiative upgrades NSDC curriculum to include IoT sensors, Stage V diagnostics, and basic data analytics, offering stipend-linked apprenticeships.

Despite these efforts, challenges remain. For instance, lack of fiscal incentives hinders the uptake of biodegradable esters, which cost 2.5 times more than mineral oil, despite spill-risk mitigation. Less than 15% of MSME presses integrate sensor telemetry. Regulatory fragmentation in India delays greenfield projects by up to six months due to separate approvals under BIS, PESO, and Chief Controller of Explosives.

However, progress is being made. The joint task force's harmonisation of standards with ISO 4413 & EU Stage V has cut SME paperwork by 30 percent and raised export readiness. The Circular-Economy Metrics for Used Oil adopts 'track-and-trace' ledgers for hydraulic oil, incentivizing recyclers with tradable EPR credits.

In conclusion, by addressing the barriers in localization, digitization, and decarbonization, India can make significant strides in improving the cost-effectiveness, performance, and sustainability of hydraulic systems while boosting indigenous technology development and manufacturing capabilities.
