For this project, the existing fire protection facilities are to be utilized, and the model of the fire pump in those facilities is ISG100-200, which is a pipeline centrifugal pump. It is not clear whether this model of pump can meet the requirements for a fire pump.
The main considerations are the pump’s flow rate and head; to meet the head requirement for the tallest building within the fire protection area, as long as these two parameters are satisfied, there should be no problems.
This model of pump should be able to meet fire protection requirements.
Centrifugal pumps are classified based on their working principle, while fire pumps are classified according to their intended use; most fire pumps are actually centrifugal pumps. Generally speaking, as long as it meets the flow rate, head, and power requirements of a fire pump, this centrifugal pump can be used as a fire pump. It should also be noted that fire pumps, as emergency equipment, have certain special requirements. For example, the P-Q curve of a fire pump should be a smooth curve without humps or corners; the pressure at zero flow rate should not exceed 140%, while the pressure at 150% flow rate should be no less than 65%. In addition, the fire pump must be capable of drawing water by self-priming, and it should start at line frequency. The power supply for the fire pump should be of the primary type, or it can be powered by a diesel engine. Finally, the fire pump should have undergone **type inspection for fire protection products; without this inspection certificate, it cannot pass the fire safety approval. According to the poster, this pump was originally part of the fire protection system; it should meet the above requirements and have passed fire safety inspections, so it should be fine to use. But it is still best to find the type inspection certification documents and recalculate whether the requirements are met using the new process parameters; after all, fire safety is no trivial matter. If negligence leads to the fire pump not being able to function when needed, the consequences would be severe.
It can definitely be used, as long as the head and flow rate meet the requirements
