1. Loosen the fastening screws (20) for the fixing plate (21) .
2. Pull out the fixing plates.
3. Remove rotating units from the shafts.
4. Pull stationary units out of the intermediate flange.
10.9 Mount pump head
Pump assembly is dependent on the specific size and shape of
the pump, and on the given shaft seal. The type of shaft seal
provided is indicated on the
“Data sheet ”.
Wrong elastomers
Pump leakage.
 Make sure that the elastomers are suited to the nature of the
pumped medium. Refer to the
“Data sheet” .
Preparation
 Clean all pump parts. Check for damage and accuracy of fit.
 Rework or replace pump parts as needed.
 Reassemble carefully under clean conditions. The seals can
easily be damaged.
 In order to reduce friction, wet the secondary seals and sli-
ding surfaces with water, alcohol or silicone grease.
 Clean the sealing surfaces of the mechanical seals with grea-
se-loosening cleaning agent, for instance “OKS 2610 Univer-
salreiniger”. After that, do not allow the sealing surfaces to
come into contact with oil or grease, and do not touch them
with your fingers.
Tip: The bonding compound “Euro Lock A64.80” is suitable for
gluing bearings and bushings in place.
Tip: The bonding compound “Euro Lock A24.10” is suitable for
gluing grub screws in place.
10.9.1 Observe markings
The feed screws must not be mixed up under any circumstan-
ces. They are assigned to the drive shaft or driven shaft, and
each have been marked with punches.
 Note the markings before installing feed screws:
– one frontal punch for the drive shaft,
– two frontal punches for driven shaft.
10.9.2 Installation of the shaft seal
1. Reinsert the shaft seal into the intermediate flange in accor-
dance with the sectional drawing (anti-torsion groove exact-
ly lateral).
2. Reinsert the fixing plates (let them snap into place) and fix
using the screws.
3. Slide rotating parts onto the shafts.
10.9.3 Mount the pump housing and feed screws
1. Attention: Feed screws are assigned either to the drive shaft
or the driven shaft. See Chapter 10.9.1 “Observe markings”,
Page 17 .
2. Push feed screws onto the shafts.
3. Warning: Rotating machine parts. Severe bruises inflicted
on hand.
 Block the feed screws with an aluminium or plastic wed-
ge.
4. Tighten the feed screw using the specified tightening tor-
que. Please refer to Table 4 “Tightening torques for feed
screw”, Page 17 .
5. Place the housing with cover onto the pump and tighten the
screws.
10.9.4 Close the pump
1. Provide the pump cover with an O-seal.
