Material pressures

Max. material inlet pressure PWork  :

The allowed working pressure has to be lower than this value. PWork can appear dynamic. This dynamic pressure can be more than PWork temporary (range of minutes). The allowed overstepping is between 10 – 20 %. It should be noted that for special products additional recommended pressure descriptions are necessary.


Maximum pressure PMax  :

This pressure must not occur dynamically. PMax can occur at DOPAG machines, when the outlet valve closes abruptly and the pump still works. Therefore this pressure has to be relieved during longer waiting times.
