The loading lance is designed for application in piggable filling plants. It is mounted at the end of a loading arm and allows pipeline pigging through the complete loading arm. The pig can transport the product into the loading lance or back into the initial source tank.
The loading lance is equipped with a level control switch. Thus the product is transported back to the tank after loading and overfilling of trucks or wagons etc. is avoided. Due to the fact that the loading arm is fully piggable, it is possible to fill several different products through the same loading arm. Product flow is controlled by a sliding sleeve installed in the loading lance. This sleeve is operated by instrument air (positions open/closed/throttle). In case of emergency air failure, the loading lance is closed automatically by spring.
Indispensable for the use of the loading lance is the piggable loading arm T91.
