Hydraulic Power Unit Design, Repair and Overhaul Services

Fairtex Group delivers specialized Hydraulic Power Unit (HPU) engineering, repair, overhaul, and maintenance services for offshore, marine, industrial, and process applications. Our services support the reliability, efficiency, and operational continuity of hydraulic power systems operating in high-demand and hazardous environments.

We design and maintain custom hydraulic power systems for a broad range of operational requirements, including electric motor-driven and diesel engine-driven HPUs up to 1400 HP. Our capabilities cover system engineering, diagnostics, component replacement, testing, commissioning, onsite intervention support, and lifecycle maintenance planning for critical hydraulic infrastructure.

Typical applications: Offshore production facilities, drilling systems, hydraulic control systems, marine equipment, industrial process plants, lifting systems, subsea support systems, motion compensation systems, and hazardous-area hydraulic installations.

What this service covers

Custom Hydraulic Power Unit Design and Integration

Fairtex designs and integrates hydraulic power units tailored to project-specific operational requirements. Our systems incorporate electric motors or diesel engine drives, hydraulic reservoirs, filtration systems, cooling systems, pressure control assemblies, and PLC-based automation packages. We also support explosion-proof hydraulic systems designed for hazardous offshore and industrial operating environments.

HPU Repair, Overhaul and Component Refurbishment

We provide workshop and onsite repair services for hydraulic pumps, cylinders, valves, accumulators, manifolds, and associated HPU components. Our repair process includes controlled disassembly, technical evaluation, failure analysis, OEM-standard replacement procedures, and performance verification testing to restore equipment functionality and operational reliability.

Testing, Commissioning and Lifecycle Maintenance Support

Fairtex conducts OEM-aligned testing and commissioning activities for hydraulic power systems to confirm performance, pressure stability, and system integrity before operational deployment. We also provide preventive maintenance programs, shutdown support, emergency repairs, technical advisory services, and field service supervision to help clients reduce downtime exposure and improve equipment lifecycle performance.
