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.

Controlled acceleration

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

Maintenance Friendly 

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.

Unmatched Reliability

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.
