Introduction
This instruction covers the installation of a Waterous CPK-
5 Series fire pump. The CPK-5 is rated at 320 GPM @ 1350
PSI (1200 l/min @ 93 bar)
The CPK-5 is available with the following transmission:
•
Extra Heavy Duty K Series - The K transmission is a
gear driven transmission designed primarily to be
driven by a power take-off or power divider. (see Figure
1).
The following installation instructions are available:
•
Priming System, F-1031, Section 3006
•
Manifold Drain Valves, F-1031, Section 3008
•
Pressure Control System, F-1031, Section 3010
•
Overheat Protection Manager, F-1031, Section 3015
Before proceeding with the installation of the CL, read the in-
structions carefully. Check the appropriate dimensional draw-
ings in the Engineering Manual as needed.
Pump Mounting - General Information
Select a mounting location which will make the pump and its
accessories readily accessible for maintenance.
Table 2 gives maximum universal joint angles for installations
where propeller shaft flanges are parallel and yokes are
aligned. Refer to this table when positioning a pump to deter-
mine proper shaft angles. Be sure to keep at least a minimum
of 1
U-joint operating angle, but do not exceed those speci-
fied in the table. This is the preferred method of propeller shaft
installation. For additional information on this method, or for
alternative methods, see driveshaft installation guidelines
such as Spicer
/Driveshaft Installation Techniques, J-3311.
CAUTION
Be sure the propeller shafts used are of the slip-joint de-
sign. Frame deflection, temperature changes and similar
factors may cause a propeller shaft without slip-joints to
produce severe axial loads on the bearings and damage
the pump.

NOTE: The angles shown in Table 2 are the maximum
recommended U-joint operating angles and are directly
related to the speed of the driveshaft. Any U-joint oper-
ating angle greater than 3
will lower the U-joint life and
may cause vibration
