4.4 Insulation shell
For pumps with provided insulation shell, the
following procedures are required to insure safe
and proper installation.
1. Pump and mating piping flange bolts need to
be installed towards the pump as illustrated
in fig. 4.
2. Apply water proof, heat resistant, silicon
based sealant to insulation shell. Care
should be taken to not block weep slots for
pump motor when applying sealant. Failure
to follow proper sealant location procedures
could damage motor and insulation shell.
See fig. 5 for proper locations when applying
sealant.
3. Mate the two insulation shells over the pump
volute as illustrated in fig. 6. If the shells do
not mate; flange bolts are installed in the
wrong direction, review step one and or
switch mating shell location.
4. Proper amount of time should be allowed for
sealant to set-up before any additional
installation work is performed. See sealant
manufactures recommended time for sealant
set-up. See fig. 7 for final configuration.
