2.
Fit sleeve O-ring (412F) into groove on shaft sleeve (126).
3.
Apply a liberal coating of an anti-galling compound (Loctite
Nickel Anti-seize
) to mixer rotor (101)
bore and shaft (122).
4.
Slide mixer rotor (101) onto shaft (122). Ensure sleeve O-ring (412F) stays in groove.
5.
Fit rotor nut O-ring (412A) into groove in rotor nut (304).
6.
Degrease rotor nut (304) and shaft (122) threads and apply ND Industries VIBRA-TITE Formula 3
thread sealing compound to threads in nut.
7.
Install rotor nut (304) on shaft (122).
8.
Prevent coupling end of shaft from turning and torque rotor nut to specified amount on
10: Model 3501 Fastener Information on page 43
.
CAUTION:
Failure to torque rotor nut can result in serious mechanical damage.
9.
Apply ND Industries VIBRA-TITE Formula 3 thread sealing compound to rotor nut set screws
(222S).
10. Install and tighten rotor nut set screws (222S).
6.16 Installation of casing foot and alignment pin
NOTICE:
Model 3501 6" and 8" mixers require a casing foot (131). The 12" mixer does not. Model 3501
8" mixers require an alignment pin on the inlet flange to ensure that the chemical injection pipe
(174) is properly oriented. The 6" and 12" mixers do not require the alignment pin.
WARNING:
Mixer components are heavy. Proper methods of lifting and securing must be employed to
avoid physical injury and/or equipment damage.
1.
For 6" and 8" mixers, determine the correct orientation of the casing from the order documents.
Model 3501 6" and 8" mixers have a transverse stationary vane in the casing (100) which must be
oriented toward the chemical injection pipe (174). The 12" mixer does not (Fig. 47).
