Mechanical Power Transmission Products for Power Generation Sector

Power Generation Sector — Thermal, Hydro & Nuclear

In power generation — whether Thermal, Nuclear, or Hydro — the stakes for power transmission are incredibly high. A single coupling failure can lead to a grid-level emergency. These environments require components that can handle extreme RPMs (up to 3,600 RPM in thermal) or massive hydraulic thrust (in hydro).

At Nu-Teck, we provide specialized Gear, Disc and Jaw Couplings, as well as Heavy Duty Gear Pinions and Customized Sprockets, to keep the turbines spinning and the plant running safely.

20 Critical Applications in Power Generation

Application-wise coupling reference for all critical drive points across Thermal, Hydro, Nuclear, and Balance of Plant sections

Application Nu-Teck Couplings Description
 
Thermal Power Plants (Coal-Fired)
Main Steam Turbine Auxiliaries Nu-Teck Disc Couplings Connect turbine shaft to the main oil pump or governor — zero-backlash and no-lube
design critical for high-speed reliability.
Boiler Feed Pumps (BFP) Disc Couplings (High-Speed) Handle thermal expansion and high RPMs (3,000+) of the feed water system without
requiring grease.
Wagon Tippler & Side Arm Charger Gear Pinions & Gear Couplings Rotate rail wagons 180° for coal unloading — customised segmented sprockets
drive the positioning chains.
Coal Pulverizer (Ball/Bowl Mills) Gear Couplings & Gear Pinions Handle the immense grinding torque required to pulverise coal into fine powder for
combustion.
ID & FD Fans Grid / Disc Couplings Provide superior vibration damping and handle the high-speed centrifugal forces of
boiler air management fans.
Coal Conveyors Tyre Couplings & Sprockets Absorb startup shock of long-distance conveyor belts — induction hardened
sprockets drive the coal feeders.
Ash Slurry Pumps Jaw / Pin & Bush Couplings Provide a fail-safe connection for pumping highly abrasive fly ash and bottom
ash waste slurry.
Hydro-Electric Power Plants
Main Turbine Shaft (Auxiliary Drives) Disc Couplings Connect the vertical or horizontal turbine to speed-sensing governors, ensuring precise
grid frequency control.
Sluice Gate & Intake Gate Hoists Gear Pinions, Brake Disc & Brake Drum Couplings Actuate intake gates and ensure they hold position safely under hydraulic
head pressure.
Governor Oil Pumps Jaw Couplings Zero-lubrication jaw couplings used in sensitive hydraulic governor circuits
for maintenance-free operation.
Trash Rack Cleaners Sprockets (Customized) Move the mechanical rakes that continuously clear intake debris and vegetation
from the water inlet screens.
Gantry Cranes (Powerhouse) Brake Drum Gear Couplings Ensure safe lifting of massive turbine runners during installation and
maintenance shutdowns.
Nuclear Power Plants
Primary Coolant Pump Auxiliaries Disc Couplings (High-Integrity) Used in backup drive systems where grease lubrication maintenance is
restricted due to radiation zones.
Control Rod Drive Mechanisms Gear Pinions & Jaw Couplings Facilitate the ultra-precise movement of neutron-absorbing control rods for
reactor power regulation.
Emergency Diesel Generators (EDG) Disc / Pin & Bush Couplings Connect backup engines to generators with high reliability during rapid-start
emergency sequences.
Fuel Handling Machines Sprockets & Chains Anti-corrosive coated sprockets and chains move spent fuel rods safely into
underwater storage pools.
Containment Ventilation Fans Grid Couplings Ensure high-speed stability for critical air filtration fans maintaining safe
pressure in containment structures.
Common Utility & Balance of Plant (BoP)
Water Treatment Agitators Gear Couplings (Vertical Mounted) Handle the axial thrust loads of vertical mixing blades in water treatment and
chemical dosing tanks.
Condensate Extraction Pumps (CEP) Disc / Tyre Couplings Allow for the parallel misalignment found in vertically mounted condensate
pump units.
Fire Water Pumps Pin & Bush Couplings Fail-safe design ensures the pump stays mechanically connected even if the
elastomer bushes wear out.
Nu-Teck's Engineering Advantage in Power Generation

Nu-Teck's specialized products are engineered to meet the zero-failure demands of power generation environments — from coal handling to nuclear containment

Coupling / Product Type Description & Engineering Advantage
Nu-Teck Zero-Maintenance Disc Couplings High-grade stainless steel spring packs require no lubrication — ideal for install-and-forget applications in high-heat
environments, BFPs, and radioactive zones in nuclear plants.
Nu-Teck High-Speed Dynamically Balanced Couplings All Disc and Gear Couplings balanced to ISO G2.5 or G6.3 for BFPs and ID Fans — protecting expensive turbine
bearings from vibration-induced fatigue failure.
Nu-Teck Induction Hardened Gear Pinions Pinions hardened up to 60 HRC for Wagon Tipplers and Puller-Pusher equipment — engineered for a service life
of 10+ years under continuous heavy-duty operation.
Nu-Teck Special Split-Segment Sprockets Split design allows tooth replacement on Coal Feeders without removing the main drive shaft — cutting
maintenance downtime by up to 80% during planned shutdowns.
Nu-Teck Labyrinth-Sealed Gear Couplings Tortuous path metallic seals keep out abrasive coal dust in the Coal Handling Plant (CHP) — preventing
premature gear mesh wear and extending coupling service life.
