1000 GPM Horizontal Split Case Fire Pump Centrifugal Water Pump
UL/FM Fire Pump Performance Requirements:
The maximum net pressure for a fire pump shall not exceed 140 percent of rated head.
( Hs ≤ 140% x H)
Inlet pressure less than 047.7 kpa. A pump shall develop not less than 65 percent or rated
total head when discharging at 1-1/2 times rated. (H 1.5 Q ≥ H x 65%)
A test is to be conducted with a positive suction pressure sufficient to achieve the maximum
brake-horsepower(KW input)required by the pump. ( P ≥ BHP)
The shut off head shall not be less than 99% of the maximum head.
UL / FM Pump Focus on safety and reliability (short-time running)
1:Working point is different.
Fire pump :highest efficiency point is near 1.5Q
-- No cavitation, no influence on water absorption performance
-- NPSHr curve is not required
2: Matching power is different
Fire pump :
-- Matching power ensures no overload at any flow rate
3: Hydraulic design is different
Fire pump :
-- The power curve is required to have an inflection point
-- The front end of curve is flat, after 1.5Q, curve fall steep
4: Strength design is different
Fire pump :(Shut off head + 50m) x 2
5: Seal form is different
Fire pump : Soft packing in principle
