Gýrol Fluid Drives
Gýrol Fluid Drives are the most practical solution to variable speed control. They transmit power at the exact speed required for the job. Smoothly. Quietly. Reliably.
Gýrol® Fluid Drives consistently achieve high reliability ratings under the most demanding conditions and in the harshest environments. In addition the reliable and proven technology is unaffected by obsolescence and does not require software upgrades or updates.
You can learn about how they work on our blog.
Why choose Gýrol Fluid Drives?
No load starting
You can therefore use the most economical driver to accelerate high inertia loads. You can also use the most economical motor and starter.
Acceleration can be controlled at any rate, once the driver has reached full speed.
Isolation of load from the driver
Isolation is especially important when applications require load to be operated intermittently
Absorbs shock and torsional vibration
Especially in irregularly loaded equipment such as extruders, conveyors and crushers
Reduces wear and noise
By allowing driven equipment to often run at reduced speeds, the noise and wear on the equipment is reduced
Transmits power efficiently
When operated at the design point
Compact and robust design
Suitable for all environments no matter how harsh or how extreme the climate
Simple (yet innovative) design, use of standard parts and no special tooling.
Infinitely variable speed control
Allowing for stepless adjustment over a wide range.
Functions as a torque limiter
Limiting the torque is required to protect the driver and load.
The wear-free transmission of power means that it is incredibly reliable
Long service life
Our Gýrol Fluid Drives have a lifespan of over 30 years.
