• Performance Features of Fire Fighting Pumps According to NFPA 20 ♦ According to NFPA 20 fire pump characteristic curve is determined by three points: 1 - Closed discharge pressure (Shut-off): The pump's off discharge pressure (zero flow valve turned off status) must not more than 140% of the rated pressure. 2- Nominal value (Rated): The pump characteristic curve must pass the intersection point or upside that point of nominal flow rate and nominal pressure. 3- Maximum Load (Overload): If required, pump capacity must be reach to %150 of operated capacity. In %150 of operated capacity,...

Used Pumps on Fire Figh In a fire fighting system, pumps can be different types: • Multi Stage Pumps (ARS, ARS-D) • Single Stage Pumps (TKF) • Single Stage In-Line Pumps (TKF-I) ■ Double Suction Pumps (SCE) ■ Boosters (SPL,SPS) Ya ng i n Pom pasinda Ku llamlabilen Pom pa I a r • Tek Kademeli In-Line Pompalar(TKF-l) • £ift Emi§li Pompalar (SCE) - Hidrofor (SPL, SPS) Type Tip • Jockey pump capacity must be at least 1 gpm or allowable leakage should be meet the required level pressure * within 10 minutes. • Should not be lower than the required minimum pressure for fire fighting system.
