Rotating Nozzles

When the inner surface of the pipe needs to be cleaned, removing grease, smaller roots, deposits or before relining, using a rotating nozzle is normally the preferred method.

On the market there are two main categories of rotating nozzles – Fast and slow rotating/spinning.

Fast rotating nozzles

The fast-rotating nozzles consist of a thrusting part with a shaft. On the shaft a rotating body is mounted and held into place by a cap. The rotating bodies are available in a variety of designs and with different water jet angles on the body. Not all fast-spinning nozzles have thrusting rear jets. Then the rotating body normally is supplied with lower jet angles, which not only clean the inner diameter of the pipe, but also thrust the nozzle up the pipe. To choose a spinning nozzle without thrusting rear jets is suitable when nozzle does not have to travel far into a pipe. For longer distances, we recommend rotating nozzles supplied with thrusting rear jets.

The fast-rotating nozzles use the water supplied by the high-pressure pump not only for the actual pipe cleaning process but also to create a gap between the rotating body and the shaft to minimize friction. Due to this construction fast spinning nozzles are therefore normally not suitable or recommended for used on recycling trucks. The reason is that recycling water contains particles that could suddenly stop the rotating motion and damage the material of the nozzle. Therefore, the fast-spinning nozzles are not suitable or recommended for use with recycling water.

Due to the fast rotation the water jets quickly fall apart after leaving the spinning part. The rotation speed varies but can be up to 3,000-5,000 rpm.

Slow Rotating Nozzles

There are many different slow-rotating nozzles on the market, e.g., Bulldog. Slow-rotating nozzles use various technical design solutions to slow down the rotation speed significantly compared to a fast-spinning nozzle. Bulldog rotated in a span between 1200 - 5000 rpm dependong on model. This means that the water jets leaving the nozzle stays together longer after leaving the nozzle and thus have significantly greater cleaning power than a fast-rotating nozzle. slow-rotating nozzles are available in several variations, many of which are suitable for use with recycled water.

Vibrating Nozzles

Vibrating nozzles are also included in the group of rotating nozzles. These are of the variant fast-rotating, but the rotating body itself is usually oscillating, i.e., not centered on the shaft. The rotation then creates a form of imbalance that causes the nozzle to "jump" in the line. Some designs have hardox or carbide on the thrusting part and cap.

Knocking nozzles are suitable when, for example, you need to knock loose solidified material at the bottom of the pipe, such as flowable fill or lighter concrete.
