Pumps & Valves

Photos by Tom W. Shand
Pump panels from earlier rigs, such as the one on this 1977 Mack CF rig, generally were more compact, with all discharges controlled via direct-acting linkages and pull rods. In later years, NFPA 1901: Standard for Automotive Fire Apparatus was changed to require that a gauge be located adjacent to the respective discharge control. Note the vernier throttle on the lower panel and the discharge relief valve in the upper right panel.
