Abstract (en)
[origin: WO9425113A1] A pump device for feeding a sprinkler system comprises a speed controlled, D.C. driven mother pump (1) which continuously maintains a stand-by pressure in the sprinkler system, and at least one slave pump (2) which is switched on when, after alarm has been given, the performance of the mother pump in maintaining the stand-by pressure has reached a predetermined part of its maximum value. The performance of the mother pump is then reduced to a predetermined lower level, and the slave pump or pumps are stopped when no more needed.
