India’s manufacturing sector is growing rapidly, particularly in the power and aerospace sectors, creating a rising need for precision, speed, and local sourcing. However, these industries still rely heavily on imported machinery, leading to challenges in repair and maintenance due to long lead times and the need for accurate parts.
As energy investments increase and supply chains shorten, OEMs and EPCs are turning to local precision manufacturers like Niranjan Engineering Works, Rajkot (Gujarat), which specializes in manufacturing Engine & Pump Parts, components for oil & gas, power generation, repair and maintenance services, the company manufactures more than 2500 different types of parts for various industrial segments.
Established in 1968, Niranjan Engineering Works began with diesel engine parts and by 1985 was supplying indigenous components to IOCL’s pipeline network. Despite early challenges in quality certifications, raw material sourcing, and skilled manpower, the company delivered localized, high-quality parts that reduced import dependency and lead times. It later expanded into repair services, ensuring OEM-equivalent performance and reduced equipment downtime.
Integrated Precision Engineering
Niranjan Engineering Works utilizes advanced CNC turn-mill machines (DMG Mori, Tsugami) to produce high-precision custom parts in small batches with short lead times.
Its in-house reverse engineering setup with Zeiss CMM enables accurate scanning and drawing creation. The company collaborates with OEMs to redesign components for better durability, reduced noise, and compactness, offering upgraded solutions for legacy systems without changing layouts. Through CAD-CAM integration and material analysis, Niranjan Engineering Works ensures enhanced performance with continuous innovation, Industry 4.0 adoption, automation, and advanced metrology tools drive its long-standing commitment to meeting evolving industry needs.
“We’re the only company offering both precision parts and repair services for engines, pumps, and valves, ensuring OEM-level performance with minimal downtime. Customers benefit from a complete, reliable solution under one roof”, states Pranav Doshi, Director, Niranjan Engineering Works.
And when it comes to CSR practices, Niranjan Engineering Works has seamlessly integrated sustainable manufacturing, eco-friendly sourcing, and green logistics into an efficient supply chain. Furthermore, through eco-conscious partnerships and environmental monitoring, it ensures minimal ecological impact.
Furthermore, the company uses advanced metrology not just for inspection but as a tool for process optimization and precision control. With a strong focus on quality and data-driven improvements, it ensures reliable performance for critical industries while supporting local units through shared metrology services.
A Meticulous Approach
Having more than 40 years in repair & maintenance services along with manufacturing technology, the company understands the complexity of repair and maintenance services. Furthermore, Niranjan Engineering Works has dedicated teams for Erection & Commissioning and In-situ Honing Services. In-situ Honing is offered for planned maintenance, while expert teams handle emergencies for fast resolution.
If we speak of growth strategies, the company believes in skill development of human resources while offering technology-driven solutions to its customers. The first step to achieve this goal is by training its engineers to enhance Repair, Maintenance and In-situ Machining capabilities. For GE Power Systems India, the company successfully delivered in-situ IP valve machining, helping the client avoid high transportation costs that exceeded the actual machining cost. In recognition of this cost-effective and efficient solution, GE Power honored Niranjan Engineering Works with the award for Most Innovative Supplier.
A Robust Future Roadmap
Over the next 3–5 years, Niranjan Engineering Works aims to become a pan-India leader in industrial maintenance and precision manufacturing, focusing on advanced repairs, in-situ solutions, erection and commissioning, precision parts, and digital services like predictive maintenance and remote diagnostics. The company plans to expand maintenance teams and response units by 2026 to cut emergency downtime by 30 percent, fully digitize service records by 2025, and establish a technician training center. To support these goals, Niranjan Engineering Works will deploy mobile machining vans and integrate CRM and ERP systems.
