Page 14 of 58
The switch panel shall be supplied and installed by the chassis manufacturer.

CHASSIS SUPPLIED FRONT BUMPER
The front bumper shall be chassis supplied and installed.
MIDSHIP MOUNT FIRE PUMP 
The fire pump shall be a Waterous CSUC20 1500 U.S. GPM (5678 LPM) single-stage midship mount
pump.

PUMP TRANSMISSION
The pump shall have a Waterous model C20 series transmission. The housing of the transmission shall
be constructed of high strength, three piece, horizontally split aluminum. The drive line shafts shall be
made from alloy steel forgings, hardened and ground to a size 2.350 inch 46 tooth involute spline. The
drive and driven sprockets shall be made of steel and shall be hardened and have ground bores. The
drive chain shall be a Morse HV™ high strength involute form chain. Bearings shall be deep groove, anti
friction ball bearings and shall give support and proper alignment to the impeller shaft assembly. Bearings
shall be oil splash lubricated, completely separated from the water being pumped, and protected by a V-
ring and oil seal. An internal lubrication system shall deliver lubricant directly to the drive chain. This
unique design eliminates the need for an external lubrication pump and auxiliary cooling. The pump and
transmission shall be easily separable. A two-piece shaft shall be splined allowing for individual repair of
either the pump or transmission, to keep down time to a minimum. All drive line components shall have a
torque rating equal to or greater than the final net engine torque.

SINGLE STAGE FIRE PUMP
The pump shall be a single stage centrifugal class "A" rated fire pump, designed specifically for the fire
service.

The pump shall be rated at 1500 gallons per minute.
PUMP BODY
The pump body shall be cast as two (2) horizontally split pieces. The body shall be made of high tensile,
close-grained gray iron with a minimum tensile strength of 40,000 PSI.

FIRE PUMP MOUNTING
The fire pump shall be mounted within a separate body module that is not directly connected to the
apparatus body.

The pump shall be frame mounted; therefore minimizing the likelihood of the pump casing cracking
should the apparatus be involved in a collision.

The pump module shall be mounted to the frame in four (4) locations and shall be reinforced
appropriately in order to carry the expected load for the life of the apparatus.
