The universal rotary joint DP is ideally suited for different media and a wide range of  pressures, temperatures, and speeds. Your advantage: you use a single rotary joint for all your applications. This reduces your diversity of variants and saves costs in maintenance and warehousing. The smooth running of the DP rotary joints allows it to be used on rollers without an additional drive – ideal for the plastics and printing industries, for example.

Your advantages

High speeds,
reduced drive power

Due to the low frictional torque, high speeds can be realized in your application When used on roller tables, roller drives can often be dispensed with.


Your rotary joint features lifetime-lubricated roller bearings and does not require any relubrication during operation at temperatures below 80°C. This reduces maintenance effort and costs.


The balanced mechanical seal prevents additional stress due to media pressure. This regulates the wear to a minimum.

maintenance stress

The seal rings and counter rings of your rotary joint can be replaced individually. This facilitates maintenance and saves costs.


Four different seal combinations for the seal face and the mating ring allow your rotary joint to be precisely matched to the required application.

For special
