American LaFrance Type 12

In 1911, American LaFrance introduced its first six-cylinder engine in the Type 12. Two more cylinders were added from the basic Type 5 / 10 motor. Although bore and stroke remained unchanged at 5-1/2 by 6 inches, horsepower was increased to 100 - powerful enough to drive the 800 gallon-per-minute gear pump. The first Type 12 (in production from 1911 to 1925) pumper was delivered to West Orange, New Jersey, later that year. The Type 12's pumping capacity was later increased to 900, then 1000 gpm. The Type 12 was also sold as the Type 45, featuring a 750gpm rotary pump. https://trucksplanet.com/models/american-lafrance-type-12-90/
