Blockages increase the risk of accidents. A well-cleaned and leak-
tight delivery line prevents the formation of a blockage.
Blockages have the following causes:
● Insufficient lubrication of the delivery line.
● Hard to pump or slightly segregating conveyed material.
● Leaks at the delivery line couplings.
