Check Coupling Alignment Pumps and drives ordered from the factory and mounted on a
common base plate are aligned before shipment. Alignment
must be re-checked after the complete unit has been installed
and piping completed. Periodic re-checking is advisable during
the pump service life.
• SPX FLOW recommends using a flexible coupling to connect
the drive to the pump. Several different types are available,
including couplings with slip or overload provisions. SPX
FLOW provides Lovejoy (Figure 24) or T.B. Woods
®
(Figure
25) couplings unless otherwise specified when ordering.
Flexible couplings can be used to compensate for end play
and small differences in alignment.
• Align the pump and drive shaft as closely as possible:
• Pump and Drive are factory aligned.
• Re-check alignment after installation and before start-up.
• Re-check alignment periodically, to maximize service life.
Check Angular Alignment
1. Using feeler gauges or taper gauges (Figure 26, items A and
B), check the alignment at four points every 90 degrees
around the coupling; adjust to equal dimension at all
points.
2. Set the space between the coupling halves to the manufac-
turer’s recommended distance.
3. Install shims to bring the system into alignment.
Check Parallel Alignment
1. Check both the horizontal and vertical alignment of the pump
and drive using a straight edge.
2. Using a feeler gauge at location “A” in Figure 27, determine
the direction and amount of movement needed (Figure 27,
item B).
3. If necessary, shim at location “C” and/or move drive as
needed.
