8.1.3 Changing the valve cartridges (only type V3014 and V3025)
Fig. 8.5
When replacing the V3 valve cartridges, ensure that
they are inserted in the correct position.
The small O-ring (Pos. 3) must be inserted so that it
points downwards (in the direction of the pump head)

Description
upper valve cartridge consists of:
1
Valve cartridge V3
2
O-Ring ø 7 x 1,5
3
O-Ring ø 2,5 x 1,5
P
Pressure side -> Pressure valve
S
Suction side -> Suction valve
The lower valve cartridge is inserted without O-rings. However, its location corresponds to the
upper valve cartridge. Therefore, the groove must point in the direction of the pump head in
which the large O-ring (Pos. 2) would fit.
