MAINTENANCE

1. Install gasket on backplate

2. Place the casing in position and close and tighten the clamp or wing nuts while lightly tapping the clamp with a

hammer to ensure even tightening. Assemble seal guard and tighten nut.

3. Assemble the cascading water attachment, if so equipped, to the adapter. Close and tighten the clamp. Assem-

ble the inlet and outlet lines to the pump. Check for strain on the casing. Adjust as necassary.

EXTERNAL BALANCED SEALS - SETTING SEAL DRIVE COLLAR LOCATION

The balanced seal is designed for outside applications, and is available with cascading water attachement. Sealing

of the process fluid along the shaft is accompished by action of the process pressure on an o-ring seal installed

in a groove in the carbon seal. The same action pressurizes the o-ring groove and augments the spring tension in

keeping a tight joint at the sealing faces. The width of the seal face contols balancing of the seal. This type of seal

should be replaced when the clearance between the carbon seal face and the backplate is less the 1/32" (.79mm),

or when leakage is noted.

To replace the seal:

1. Disconnect the inlet and outlet lines, and remove the casing, impeller and backplate.

2. Assemble the spring, seal cup, o-ring seal and carbon seal, and install as a unit, taking care that slot in seal cup

is aligned with pin on drive collar. Gentle finger pressure will overcome o-ring resistance on the shaft.

When the carbon seal is replaced, the location of the drive collar should be checked and relocated of necessary, by

one of the two following methods.
