Pressure Relief Valve For Fire Pump_In UL/ FM Listed - TPMC

Pressure relief valve (PRV) opens and closes automatically at a pre-set pressure to relieve excess pressure so to protect fire pump. When fire pump starts and the set pressure is exceeded, the pressure relief valve opens and a portion of the water is diverted through the auxiliary route, and the pressure inside the pipeline stops rising. Once it reaches the valve’s reseating pressure, the

Understanding ISO Ratings – Worden Fire and Aulance

To quote an old Olympia beer ad, “It’s the water!”. A 1500 gpm pumper is no better than a 50 gpm brush truck without water. To improve a rural ISO rating, a fire department needs to focus on developing their water supply capabilities. How ISO Calculates Pump Flow rate. ISO bases pump flow rate on the NFPA pump rating at 150 psi. Thus, if
