Disassembling the
pump
Disassembling and assembling APP 11-13 and APP 16-22
Important: It is essential that the pump is
serviced in conditions of absolute cleanliness.
Place the pump on a pallet or other stable
surface above the ground. Ensure that the pump
cannot roll. It must be possible to place the
pump vertically with the shaft pointing down-
wards. This can be done between two pallets or
between two boards on a pallet provided that
the distance to the ground is minimum 100 mm.
(3,94 inches). See example page 4 item 7.
1.
Disconnect the pump from the rest of the
system.
2.
Using the 10 mm combination wrench,
unscrew the four bolts from shaft seal
flange. If shaft seal flange is stuck, place
two bolts in threaded holes in shaft seal
flange to remove it.
