pompe d'excès de pression

OBS: pompe de surpression : désignation uniformisée par le Comité du projet de lexiques (Nouveau-Brunswick).

CONT: The excess pressure pump is designed to increase the pressure on the sprinkler system to a value substantially above the maximum pressure likely to occur in the mains. The object of this is to prevent a false alarm of fire since water flowing into the sprinkler system would automatically sound an alarm.
OBS: excess pressure pump: designation officially approved by the Lexicon Project Committee (New Brunswick).
