When a multi-purpose equipment, should consider more than one fire pump in parallel, the flow superposition of fire pump outlet pressure. The choice of fire pump, the pump performance curve should be smooth without hump, fire pump zero flow pressure should not exceed 140% of the system design rated pressure, when the pump flow rate of 150% of rated flow, then the fire pump pressure is not Should be less than 65% of rated pressure. Fire pump motor shaft power pump flow should meet the head of the curve at any point on the job requirements.
