CHECK AT 4 POINTS AROUND
COUPLING-EVERY 90°
In-line Drives. For initial pump installation, and for rechecking alignment, the following steps are
advised:
Use a flexible coupling to connect the drive to the pump. Many different types are available, including
couplings with slip or overload provision.

A flexible coupling is used to compensate for end play and small differences in alignment. The
pump and drive shaft should be aligned as closely as is possible.
Check angular alignment:
Using feeler gauges, or taper gauges.
Adjust to get equal dimension at all points. At the
same time set space between coupling halves to
manufacturer’s recommended distance.

Check parallel misalignment: Use straight edges and shims:

After piping is complete, and drive and couplings are aligned, turn pump shaft manually
to see if it turns freely without binding.
Note: Covers have been removed for illustration purposes only. The pump
cannot be operated with the cover removed.

Check rotation direction of drive to see that pump will rotate in proper direction.

CONNECT COUPLING HALVES AND INSTALL COUPLING GUARD.
Determine rotation direction by looking at the motor coupling.
