7.4.2 Assembly
1 Clean and degrease the fitting edge of the pump casing where the wear ring is to be
mounted.
2 Degrease the outer edge of the wear ring and put a few drops of Loctite 641 on it.
3 Fit the wear ring in the pump casing. Take care it is not pushed out of
alignment!
7.5 Disassembling the pump
Start at paragraph 7.5.1 "Back Pull Out-unit" and follow all instructions up to and
including the part you want to remove.
The item numbers used refer to the parts lists and drawings of chapter 9 "Parts".
7.5.1 Back Pull Out-unit
For maintenance and repairs usually it is not necessary to remove the whole pump from
the piping. You only have to remove the integrated pump cover/motor-part, the so called
"Back Pull Out-unit".
!
NEVER start dismantling by loosening the motor fastening nuts (0900). This
may result in irreparable damage to the motor shaft and the mechanical seal!
