Gas and Steam Turbine Gearboxes – Power Generation

Our units are installed in critical operations around the world, including oil rigs, chemical plants, hospitals, and localized power stations. These gearboxes are designed to meet demanding performance requirements and ensure maximum reliability.

Design Features	Generator-mounted gearboxes Turbine-mounted gearboxes Lubrication pump, fuel pump, etc., power take-off (PTO) drives Starter-drive, power take-ins (PTIs) Integrated barring drive gear Instrumentation packages for condition monitoring Integrated lubrication systems
Applications	Used in power generation for oil rigs, chemical plants, hospitals, and power stations.

Vertical Epicyclic Gearboxes – Cooling-Water Pumps

Our vertical epicyclic geared pump drive enables significantly smaller electric motors compared to traditional direct-coupled motor drives. This size reduction contributes to substantial cost savings in installation and operation of a typical circulating pump package.

Key Design Features	Gear units designed to suit motor and pump interfaces Gearcase can be designed to support the weight of the drive motor Reduced overall package size Coaxial drive train (motor, gearbox, pump) 99% mechanical efficiency Self-contained full-duty lubrication system Reduced noise and vibration Transfers thrust or accepts external thrust via integral thrust bearing Eliminates the need for a low-speed coupling
Efficiency	99% mechanical efficiency
