WELDED BELLOWS VS. TYPE 9

Balance: The Bellows is inherently balanced. The Type 9 requires a costly step in sleeve or shaft.
Dynamic Elastomer: Eliminated in a welded bellows. Teflon wedge in a T9 is most common reason of failure.
Even Face Load: Bellows applies one consistent 360 degrees load on the opposing face. One clogged spring can open T9 faces.
Self Cleaning: Bellows naturally throws product away from compression unit; T9 traps product in it's springs.
Single Piece Construction: Bellows has 1 piece, Type 9 has 16 pieces.
Elastomer Location: T9 wedge directly behind heat of the faces; Bellows "o" ring is as far away from heat source as possible.

INSTALLING COMPONENT SEALS

1. Lubricate "O" Ring and install seat squarely in the gland
2. Determine position of stationary seal face in relationship to stuffing box face and scribe mark on your "blued shaft" where faces will meet
3. Measure back the distance of the seal's operating length and scribe another mark
4. Slide gland with installed seat over shaft and leave unattached
5. Lubricate "O" Ring and slide seal over shaft to operating length mark
6. Lock set set screws
7. Reassemble stuffing box
8. Slide gland plate up to stuffing box and tighten gland nuts
9. Reassemble pump, turn shaft by hand to check for free rotation, and attach piping
10. Flood pump, vent air and start
