This also applies to hydraulic oil, which must meet high purity and high temperature resistance. To ensure that the hydraulic oil produced meets these standards, a special filter was developed that guarantees high-quality hydraulic oil, free from undesirable solid particles. The filter basket is installed at the end of the loading arm, at the filling head, and is equipped with a quick-change coupling. In the final process step, the pig conveys the medium directly into the filling head and the connected filter basket. This is an example of a demanding pigging process, which extends directly into the tanker.
