Changing the Orientation of the Fluid Inlet
and Outlet Ports
On aluminum pumps, the fluid inlet and outlet manifolds
have threaded ports on both ends. The pump is shipped
with a plug installed in one end of each manifold, and the
opposite end open. See Fig. 5. To change the orientation of
the inlet and/or outlet port, remove the plug from one end
of a manifold and install it in the opposite end.
