Abstract

A firefighting pump transmission (20) for use with an emergency vehicle pump comprising a PTO gear (32) affixed to a drive shaft (34) of the transmission (20) and an impeller clutch driving gear (30) affixed to the drive shaft (34) adjacent the PTO gear (32). The clutch driving gear (30) may couple with a multi-disk clutch (38) to turn an impeller shaft (40). The transmission (20) allows for changing the gearing of the PTO without affecting the ratio or speeds of the impeller driving mechanism, and vice versa. The dual gears on the drive shaft accommodate compatibility with a Commercially Available PTO device to be mounted to the housing of the transmission to power a variety of devices.
