Install the discharge head

CAUTION:

• Do not bump or scrape the shaft protruding above the column. This could result in a bent or

damaged shaft.

• Packed stuffing boxes are not allowed in an ATEX-classified environment.
• The mechanical seal used in an Ex-classified environment must be properly certified. Prior to startup,

make sure that all areas that could leak pumped fluid to the work environment are closed.

NOTICE:
Make sure that the eyebolts or slings are rated to handle more than the pump weight.

Mechanical seals are shipped separately. If the seal housing is assembled to the discharge head, remove the
seal before you begin this procedure.
1. If the stuffing box is assembled to the head, remove it and all attached piping.
2. Remove the coupling guard:

a) Attach shackles to the discharge head lifting lugs, or thread two eyebolts in the head driver-

support mounting holes diametrically opposite each other.

b) Hoist the discharge head over the protruding headshaft.

3. Orient the discharge head in the required position:

a) Lower the head while you center the vertical hole with the headshaft that protrudes above the

column.
Stop when the discharge head engages the column.

b) Install the capscrews and secure the discharge head to the column.
c) Tighten the capscrews gradually in diametrically-opposite pairs.

4. Lift the pump assembly high enough to allow for the removal of the supports.
5. Install and tighten the remaining capscrews until all capscrews are uniformly tight.
6. Hoist the bowl, column, and head assembly and remove the supports.
7. Lower the bowl, column, and head assembly until the discharge-head mounting flange engages the

barrel flange.

8. Secure the discharge head to the barrel flange.

Stuffing box installation

CAUTION:

• Make sure the split gland fits squarely in the stuffing box. A split gland that is not properly seated can

cause uneven compression of the packing and damage to the shaft or sleeve.

• Packed stuffing boxes are not allowed in an ATEX-classified environment.
