temperatures above 160

use at higher operating temperatures.
Assemble the stationary seat and gaskets in the
seal clamp (7) and secure to the seal plate (31).

over the impeller shaft (18) and temporarily secure
the seal plate to the pedestal (13) using two cap-
screws and nuts (1/2 UNC X 1 1/2 inch long, not
supplied).

or a very small amount of oil, and slide the rotating
portion of the seal assembly onto the shaft sleeve.

sleeve with the retainer just flush with the impeller
end of the sleeve. Tighten the retainer setscrews

cause personal injury. Failure to remove
