FIELD: fire safety.

SUBSTANCE: bench for testing of fire pumps comprises a water reservoir 6, where a fire pump 8 is installed with the help of a suction sleeve 7. Also the bench comprises a vacuum metre 5 and a manometre 4 with dampers. A pipeline 2 with a flow metering device 1, which is an orifice with a conic hole installed between two flanges via the gaskets, are connected to nozzles on a discharge header of the pump 8 with the help of discharge sleeves 3. The difference in the head at the left and at the right from the orifice is monitored by a differential manometre 10 of membrane type, the electric signal from which arrives to a metering potentiometre 9, which is calibrated by the head difference by feed value Q, l/s of the pump 8, at the same time the pump 8 adjustment to pick up the complete discharge curve Q-H is carried out by means of gates 11, 12 of rough and fine feed adjustment.
