4.
Install alignment rods through the upper half and into the tapped bottom half, one on the suction
side and one on the discharge side above the horizontal center line of the casing.
An alignment rod is a threaded rod that screws into the bottom half of the casing and is approxi-
mately 2 in. (5 cm) longer than one half of the impeller diameter. This prevents the top half from
falling onto the impeller and also helps with alignment while installing the upper half. If alignment
rods are not supplied with the pump, then they can be made from a threaded rod.
5.
Place nylon slings around upper-half casing ears and pull the slings taut so that they cannot slip off.
