2.6 Connection of 709 IC Pump

732 IC Detector / 733 IC Separation Center

2.6.4 Filter unit Manufit

The optional 6.2821.000 Filter unit Manufit (see section 7.3.1) is in-

stalled between the 709 IC Pump and the injection valve at the 733 IC

Separation Center. The filter unit serves to avoid contamination of the

piston seals by abrasive particles and can be used in the pressure

range 0…50 MPa (0…500 bar) for non metal-free systems together

with steel capillaries. It is installed as follows (see Fig. 12):

1 Prepare Manufit housing

• Insert outlet capillary 6363 with steel mesh holding end 6161 into

Manufit housing 6262.

• Insert the 4 steel meshes 6060 provided into the steel mesh

holding end 6161.

• Press the PTFE gasket 5959 into the steel mesh holding end

6161.

2 Prepare Manufit pressure screw

• Insert inlet capillary 5656 with counterpart end 5858 into Manufit

pressure screw 5757.

3 Assembly

• Fit the two capillary end pieces 5858 and 6161 together.

• Screw Manufit pressure screw 5757 and Manufit housing 6262

firmly together.

To replace contaminated steel meshes, proceed in the reverse order.
