500 Series Mixer Installation
- Remove blank coverplate from tank manway and check mixer coverplate for correct size, hole location and orientation.
- Install nozzle gasket and bolt mixer to nozzle.The mixer pinion shaft must be in line with "TOP" stamped on the flange edge of the nozzle.
- Mount propeller on shaft if the manway is large enough for the propeller to roll through.
- Install gasket and bolt coverplate with mixer to the manway.Mixer pinion shaft must be vertical when mixer is bolted to the manway.
- Mount electric motor to the motor mount if it was not factory installed. Install motor mount, with motor attached, onto the adapter and install the cap screws.
For motor coupling alignment, see the Startup & Operation tab.
Motor Coupling Alignment
Jensen Series 500 mixer couplings have precisely machined edges for easy alignment using only a straightedge.
A — Oversized holes in motor mount
Parallel alignment
B — Shims under motor feet
Parallel & angular alignment
C — Set screws
Angular alignment & coupling gap
D — Oversized holes in motor mount base
Parallel alignment
Final alignment should be made by lightly tapping the motor mount while mounting bolts are snug but not fully tightened.
Flexible Coupling Torque
| Model | Torque |
|---|---|
| 505 | 120 in-lb |
| 520 | 120 in-lb |
| 550 | 240 in-lb |
Flexible Coupling Element Installation
Removal
- Remove coupling cover.
- Remove bolts from the motor and gearbox coupling halves.
- Remove the flexible element. (It is not necessary to remove the gearbox-half bolts when removing the gearbox.)
Installation
- Position one cap screw.
- Pivot the flexible element into position.
- Install remaining cap screws.
- Tighten evenly to specified torque.
Do not overtighten — this can strip threads or bend cap screws.
