14. Assemble the inlet and outlet lines to the pump. Check for strain on the casing. Adjust

as necessary.

Note: Apply a small amount of food-grade lubricant to the o-ring prior to installation. Do not

lubricate the carbon seal with any type of oil or grease. The seal faces are lubricated by the

product being pumped.

6.3 Setting The Seal Drive

Setting The Seal Drive Collar By Position

1. Assemble the spring, seal cup, seal o-ring, and carbon seal onto the drive collar. Care

must be taken so that the spring does not rest on the tab that is bent back. A portion

of the spring is offset to provide clearance for this tab. Care must be taken to ensure

that the pins on the drive collar are in line with the slot on the cup.

2. Install as a unit on the shaft.

3. Install the backplate and casing.

4. Install and tighten the casing clamp.

5. Slide the drive collar and seal assembly toward the backplate until the nose of the

drive collar pushes the o-ring and carbon seal tight against the backplate.

6. Slide the drive collar away from the backplate 1/32" (.79mm) and secure the drive

collar in this location with the set screws.

7. When the drive collar is properly positioned and seal components are properly

installed, the pump shaft should rotate freely by hand. If excessive effort is required to

rotate the shaft, check to be sure that all components are properly installed and the

drive collar is properly positioned.

Note: Extra care should be taken when assembling C series pumps with type DG seal.

Incorrect stub shaft settings will allow the impeller hub to contact the inboard face of

the stationary seal seat. Interference of impeller hub and seal seat face will cause wear of

impeller hub and damage the inboard or secondary seal face of the clamped-in-seat. Usual

inspection is recommended after installation of the impeller, and before installation of casing,

to ensure clearance between the impeller hub and seal face. If no clearance is visible, the

pump should be disassembled and the stub shaft moved forward to provide at least 1/32

(.79) mm clearance between the impeller hub and seal seat face. Reset seal drive collar if

necessary. Rotate freely by hand; if excessive effort is required to rotate the shaft, check to

be sure that all components are properly installed and the drive collar is properly positioned.
