9. CASING ASSEMBLY
Once the impeller has been installed, the casing must be mounted. Place the casing gasket
(90) onto the groove on the backplate (
11, 11B, 11H or 11P
, depending on the seal type).
Take the casing (
1
) and place it onto the adapter, positioning the discharge at the desired
location. Take the clamp assembly (
75
) and place it around the casing. Tighten the clamp to
close the casing so that it is level around the perimeter. A rubber mallet may be helpful when
installing the casing.
10. BEFORE TURNING ON THE PUMP
•
Check that the motor turns in a counter-clockwise direction.
•
Keep the suction line flooded and the mechanical seal lubricated with the fluid which is
going to be pumped. Never operate the pump when dry or it may damage the seal.
•
Maintain a sufficient NPSH available in the suction line (please see the section on piping).
