Filter unit PEEK
The 6.2821.100 Filter unit PEEK (see Fig. 11) supplied with the 709
IC Pump is installed between the 709 IC Pump and the injection valve
at the 733 IC Separation Center. This filter unit serves to avoid contami-
nation of the piston seals of the 709 IC Pump by abrasive particles and
can be used in the pressure range 0
…
25 MPa (0
…
250 bar).
The two filter units PEEK supplied with the 2.733.0X30 IC Separation
Center (with suppressor) are installed between the 752 Pump Unit and
the inlet capillaries for regeneration and rinsing solution. These filter
units serve to protect the suppressor module from foreign particles and
bacterial growth.
The 6.2821.100 Filter unit PEEK consists of the housing 54
54 and the two
connectors 53
53 (with filter) and 55
55 (without filter) screwed into the hous-
ing 54
54. For the connection of capillaries 51
51 PEEK compression fittings

53 with filter are avail-
able as an option with the ordering number 6.2821.110 (set of 10).
