Disassembling

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.

Disconnect the pump from the rest of the

system.

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.

For a better understanding of the pump, please

see exploded views on page 15 to 17.

WARNING:

Do not reuse disassembled O-rings or shaft

seal as they might be damaged. Always use

new O-rings.

Remove ceramic ring from flange by

carefully pushing it from the back of the

sealing ring.
