(6) Rotate the pump by hand to make sure the
impeller is not binding or scraping. Shims (12) can be
added behind the impeller to center the impeller in the
volute. The clearance between the front of the impeller
and the seal plate should be equal to the clearance
between the back of the impeller and the pump casing
(fig. 8-4).
