Brief Introduction of Synchronous Drainage and Suction Fire Pump The synchronous drainage and suction fire pump is a self filling water intake fire pump installed above the liquid level. Since the pump axis plane of the pump is always below the liquid level of the front self filling device, when the pump is started, the water naturally flows back into the pump under the action of gravity, so it can discharge water in zero seconds. In addition, the pump also has self-priming function while satisfying self irrigation. The self-priming height can reach 8.5m, and the horizontal distance of inlet pipeline -
