After the grout has hardened, tighten the anchor bolt nuts. Check and correct the motor shaft
alignment. We recommend the actual shaft misalignment for the flexible couplings be considera-
bly less than the maximum allowed by the coupling manufacturer for long coupling life and re-
duced vibration levels.
Connection to Pump Driver
The pipe hung pump is connected to the driver via a drive shaft and universal joints at each end. Follow
the drive shaft installation instructions and the angle limits per the pump installation drawing. An extenda-
ble guard is provided for the drive shaft and should be used any time the pump driver is rotating.

4.4 Drive Alignment Procedures
Alignment procedures must be followed to prevent unintended contact of rotating parts.
Follow coupling manufacturer’s installation and operation procedures.
WARNING:
Before beginning any alignment procedure, make sure driver power is locked out. Failure to
lock out driver power will result in serious physical injury.
Lock out driver power to prevent electric shock, accidental start-up and physical injury.
The AF pump comes with two drive variations, V-belt and gear driven. Accurate alignment of both sys-
tems is essential to long pump life and reduced pump problems.
The points at which alignment are checked and adjusted are:
•
Initial Alignment
is done prior to operation when the pump and the driver are at ambient tempera-
ture.
•
Final Alignment
is done after operation when the pump and driver are at operating temperature.
Alignment is achieved by adding or removing shims from under the feet of the driver and gearbox and
shifting equipment horizontally by adjusting bolts as needed.
