Mechanical balance of plant

Mechanical balance of plant

The critical mechanical infrastructure engineered to perfectly match the requirements of turbine operation in any circumstances.

A Tier-1 hydro-mechanical unit is only as reliable as the auxiliary infrastructure supporting it. Litostroj Power Group eliminates the integration risks of multi-vendor procurement by designing the complete mechanical balance of plant in-house.

From high-pressure Hydraulic Power Units (HPU) through cooling, drainage and lubrication systems all the way to compressed ari systems, we deliver the essential mechanical ecosystem required for safe, continuous Water-to-Wire generation.

Operational parameters

Hydraulic power units:Operating pressures up to 25 MPa in genera and up to 16 MPa for Kaplan runners
Water conveying systemsAdvanced systems with feedback loops enable precise control of the equipment.
Environmental safetyFully integrated automatic oil separators and closed-loop cooling.
Compressed air systemsA mere powerplant service air or advanced reversible unit air depression system

Hydraulic part of governor

Hydraulic power units (HPU)

Maximize the potential of your hydro turbine control with our hydraulic governor systems—available in open-loop and closed-loop configurations. They deliver instant, precise speed and load regulation, responding to grid changes in real time.

Prevent overspeed, pressure spikes, and mechanical stress while maximizing efficiency and grid stability. Protect your investment, boost performance, and reduce downtime. Smart control – powerful results.

Cooling and drainage

Cooling systems

Optimize your hydro plant with our cooling solutions for bearings, generators, and hydraulics. Choose open-loop or closed-loop systems—both deliver superior heat dissipation, prevent downtime, and protect critical equipment. Extend lifespan, boost efficiency, and cut maintenance costs. Reliable, effective, and tailored to you. Stay cool – stay ahead.


Drainage & ecology

Plant-wide drainage networks integrated with automatic oil separators effectively manage infiltration through turbine casings, preventing costly damage to mechanical components. With reliable drainage system your facility operates safely and efficiently while minimizing repair expenses and downtime.

Lubrication systems

These precision solutions deliver the right lubricant at optimal pressure and temperature to all critical bearing surfaces, reducing friction losses and maintaining alignment integrity.

With reliable lubrication technology, your hydroelectric installation achieves superior operational efficiency, minimal maintenance downtime, and maximum return on your equipment investment.

Compressed air systems

Power your hydro facility with our compressed air systems. Essential for cavitation protection, blow-down, valve actuation, and precise pressure control.

Reduce maintenance, extend equipment life, and ensure smooth, reliable operation. Efficient, dependable, and built for performance. 

Breathe life into your turbines.
