What is a Flexible Shaft (Wet Cleaning)?
With the Flexible Shafts (Wet Cleaning), you can wet clean virtually any tube from 7 to 25 millimetres. It is used in combination with a Tube Cleaning Machine and brushes, often to clean Heat Exchangers, Condensers, Chillers and other Coolers. The brush is guided rotating through the tube, and loosens the deposits through continuous contact with the tube. As the brush loosens the deposits, the water flows through the shaft into the tube and the loosened deposits arr flushed away.
Here a short explanation video of the cleaning method, where you also see the blue flexible shaft in operation:
By means of a sturdy nylon mantle with a galvanized shaft on the inside, these shafts are the forerunner within the industry. The most important starting point when using the flexible shafts is to use the right shaft for the right pipe diameter (ID).
Some features of Goodway Flexible Axles:
- Galvanized steel flexible core
- Strong nylon jacket in the hose (durable)
- Connection possible in Quick-Connect (quickly operational)
- Universally applicable (fits on any Goodway Tube Cleaning machine)

What are the differences between all Flexible Shafts?
What is the difference between a 701 and a 703 axle? This is the thickness of the shaft. Some pipes, for example, are 12 mm I.D. diameter. It is therefore not possible to pass through it with a 15 mm flexible shaft. So you have a different axis for each thickness of pipe. Below are 2 handy tables with the most important characteristics of each type of axle.

Number of advices from practice, when choosing your Flexible Shafts:
- Always make sure that the flexible shaft is as close as possible to the pipe in millimetres. For example, if your tube I.D. is 16 mm, we recommend selecting a shaft with 2 to 4 mm underside (depending on the soiling), for the most effective cleaning possible.
- The longer the shaft, the more torsion is exerted on the core of the shaft. This allows the shaft to wear faster.
- Always consider the space you need to bridge from machine to pipe bundle. If your pipe bundle is 5 meters long, but you can't get close to the bundle, we advise for example to take a little more length, about an extra 1.5 to 2 meters. This avoids skipping the last part of the pipes.
- If possible, choose a 'Quick-Connect' version. This further optimises your cleaning processes, because the machine, flexible shaft and brushes are fully coupled in one operation. This way you will be operational with the entire Tube Cleaning Set (TIME = MONEY) in one minute.
