Over 21 couplings feeding the boilers
The boiler feedwater pumps at CORPOELEC's Rankine-cycle thermal plants turn through over 21 Voith R17 K 550 variable-fill hydrodynamic couplings of 6,800 kW: they transmit motor power to the pump through oil, without mechanical contact, and regulate flow to match steam demand.

01
THE CHALLENGE
Start high-power motors without current peaks or water hammer, regulate feedwater flow without wear and protect motor and pump against blockages or extreme load swings.
02
THE SOLUTION
R17 K 550 couplings with SBR 200 input and TSBZ 125 output connecting couplings. RELANSA runs the on-site turbo-coupling inspection protocol: vibration analysis, infrared thermography, oil pressure and temperature, scoop tube, ISO 4406 sampling, cold laser alignment and fusible plugs.
03
THE IMPACT
A fleet served locally, with precision diagnostics and direct access to Voith's OEM support for spares and factory assistance.
// TURBO-COUPLING INSPECTION PROTOCOL
- —Vibration analysis at motor-side and pump-side bearings
- —Infrared thermography of bearing housings and coupling body
- —Working and lube oil pressure; heat exchanger inlet and outlet temperature
- —Visual inspection of shaft seals and connections; free movement and calibration of the scoop tube
- —Oil sampling and analysis: viscosity, acid number, water and ISO 4406 particle count
- —Cold laser alignment motor–coupling–pump; fusible plug check
