Every Fluidomat coupling transmits power hydrodynamically — through oil, not metal contact — so drives start soft, run protected and last longer. Choose the principle your machine needs.
Fixed-speed SM, HF, SMP and T-series with delayfil control for soft no-load motor starts and adjustable starting torque from 120%.
View fixed-speed rangeStepless speed control up to 5:1 from a fixed-speed motor. Ideal for fans and pumps where speed control turns into real energy savings.

Our capabilitiesThe complete Fluidomat range — fixed-speed, variable-speed and fill-control couplings for drives up to 6000 KW.
In centrifugal machines, power demand falls with the cube of speed. By varying oil fill through a sliding scoop tube, a Fluidomat SC coupling gives stepless speed control on a rugged squirrel-cage motor — replacing wasteful throttle control and earning money back through energy savings.

BHEL, L&T, EleconFluidomat is one of a select few coupling makers in the world with its own technology — so we engineer the answer, not just supply a part.
We study your drive, duty cycle and site constraints to define the real problem and the energy opportunity.
Our designers size and select — or custom-build — the right coupling using in-house AutoCAD & SolidWorks expertise.
Cast in our own non-ferrous & CI foundries, machined and performance-tested under our ISO 9001 quality system.
Installation, commissioning and lifetime application support — backed by a global representative network.
Fluidomat’s management systems are independently certified to international standards — covering the design, manufacture, supply, installation and commissioning of our couplings.
About our quality systems
EnergyA custom scoop-control coupling let the plant open the damper fully and run the fan at 400–600 RPM — saving 400 KW.

TechnicalA fluid coupling enables no-load motor start at full voltage, with one current kick instead of two and 5–7× less heating.
Read the noteA fluid coupling transmits power between a driving and driven shaft through oil rather than mechanical contact. An impeller accelerates the oil, which drives a turbine runner — giving soft starts, overload protection, vibration damping and (in variable-speed types) stepless speed control, all with no wearing parts in the drive path.
For fans and pumps, power demand falls with the cube of speed. A variable-speed scoop coupling controls flow by reducing speed instead of throttling — saving 10–40% of energy. Fluidomat couplings are recognised as energy-saving devices by the Government of India.
Choose a constant-fill (fixed-speed) coupling when you need soft starting, motor protection and load sharing at constant running speed. Choose a variable-speed scoop coupling when the process benefits from speed control — typically fans, pumps and slurry duties. Our engineers will recommend the right type for your duty.
Fluidomat couplings serve industrial and automotive drives up to 6000 KW — fans, pumps, conveyors, crushers, mills, shredders and IC-engine drives across power, cement, steel, metals, paper, fertilizer, chemical and port industries.
Yes. As one of the few coupling makers worldwide with its own technology and in-house foundries, Fluidomat regularly custom-builds couplings to fit existing shaft-to-shaft distances, space and torque envelopes — exactly as we did for NTPC and Indo Gulf.
Fluidomat is certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018, covering design, manufacture, supply, installation and commissioning. Application engineering and energy-saving support are part of every project, backed by domestic and international representatives.
