2.2 Mounting the pump head
1 Remove the transportation lock
To ensure that the pump drive is not damaged during transport
a black plastic block is mounted in place of the pump head on
the right side of the 818 IC Pump front panel. This transport
safeguard block has to be removed after undoing the four
screws 9.
To avoid any damage to the pump head, the protective block must be
remounted if the pump has to be moved any great distance.
2 Mounting the pump head
The Pump Head 8 (6.2824.100) with integrated piston units is
unpacked and fixed in place of the transport safeguard block
with the four hexagon screws 9as shown in Fig. 2 .
To ensure that the pump head is not positioned wrongly, the holes at
the rear for the clamping bolts have different depths, i.e. 1 clamping
bolt is longer than the rest. The deepest hole must naturally
accommodate the longest bolt. If this is not the case, the pump will
not function properly.
3 Connecting capillary to pump head
The connection capillary 6 fastened to purge valve 2 is
screwed onto the pump head 8 as shown in Fig. 2.
The pressure range of the 818 IC Pump with the 6.28.24.100 PEEK
pump head isf 0 … 30.0 MPa (0 … 300 bar)..
