ALL THE PUMP YOU NEED AND MORE
Revised 7-5-12
Installation
Installation Recommendations –
 It is recommended that an isolation valve be installed on the discharge side of the pump. This will allow
for ease of service and can also aid in the start up procedures.
 All pipe, valves and fittings should be at least the same diameter as the discharge pipe or sized in
accordance with good piping practices to reduce excessive fluid velocities and pipe friction losses.
 Before the pump is installed, it is recommended that the discharge piping be pressure checked to at least
40 psi or as required by codes and local regulations.
 Whenever possible avoid high pressure loss fittings, such as elbows or branch tees.
 It is recommended that the discharge pipe is ten pipe diameters in length before the nearest fitting.
 The piping should be adequately supported to reduce thermal and mechanical stresses on the pump.
 Good installation practice recommends that the system be thoroughly cleaned and flushed of all foreign
materials and sediment prior to pump installation.
 It is recommended to adequately support all elbows and tees immediately after pump connection. Excess
turbulence can be created when pipe fittings are installed close to the pump discharge, causing vibration
or movement if not properly supported.
Unpacking Instructions –
The CR pump end will ship separate from the motor. The seal is not installed, due to the potential damage that
may be caused during shipping to the ceramic face. There is a white teflon support bushing holding the pump
shaft stationary. The seal carrier must be taken off the pump and the white teflon support bushing must be
removed prior to installation.
Located the box with the shaft seal & follow instructions in the shaft seal box.
Proceed to the next step.
Motor/Pump Assembly –
1. Remove key from motor shaft, if present, and
discard.
2. Thoroughly clean the surfaces of the motor and pump
end mounting flange. The motor and shaft must be
clean of all oil/grease and other contaminants where
the coupling attaches. Set the motor on the pump
end.
3. Place the terminal box in the desired position by
rotating the motor.
4. Insert the mounting bolts, then tighten in a cross
pattern evenly. For 3/8” bolts (2 HP) torque to 17 ft.-
lbs., for 1/2” bolts (3 to 5 HP) torque to 30 ft.-lbs.
WARNING: Be sure to anchor piping properly as two-way control valves may cause water
hammer resulting in excessive pipe movement. Possible pump and pipe damage may
occur if the system is not properly anchored.
WARNING: The following instructions are specific for the pump noted. Please take note of
the pump being installed. Pump model is designated as CR__-_ (i.e. CR31-1).
