Align non-spider type couplings by using a feeler gauge or taper gauge between the
couplings halves every 90 degrees. The coupling is in alignment when the hubs are the
same distance apart at all points (see Figure7 above).
Check parallel adjustment by laying a straightedge across both coupling rims at the top,
bottom, and side. When the straightedge rests evenly on both halves of the coupling, the
coupling is in horizontal parallel alignment. If the coupling is misaligned use a feeler
gauge between the coupling and the straightedge to measure the amount of
misalignment.
V-Belt Drives
When using V-belt drives, the power source and the pump must be parallel. Use a
straightedge along the sides of the pulleys to ensure that the pulleys are properly
aligned (see Figure 8 below). In drive systems using two pr more belts, make certain
that the belts are a matched set; unmatched sets will cause accelerated belt wear.

Tighten the belts in accordance with the belt manufacturer's instructions. If the belts are
too loose, they will slip; if the belts are too tight, there will be excessive power loss and
possible bearing failure. Select pulleys that will match the proper speed ratio; over
speeding the pump may damage both pump and power source.
Do not operate the pump without the guard in place over the rotating
parts. Exposed rotating parts can catch clothing, fingers, or tools,
causing severe injury to personnel.
DANGER!
