8. Install the piping connection flanges in their places on
the suction and discharge side of the pump but do not
tighten the bolts.
9. Move the rotor to its lowest position (by rotating counter
clockwise). Refer to Chapter 6.2.2.
10. Push the top of the hose inside the pump housing,
behind the front hose guide.
The hose can be installed despite the plastic hose guides
inside the housing in models LPP-T65 (LPP-T 2.5) and
LPP-T80 (LPP-T 3). Ensure, however, that the hose is not
squeezed between the hose guides and the rotating rotor
during installation, as this may damage the hose.
11. Rotate the rotor slowly a few times so that the hose
sets in the right position.
Important:
Ensure that
the gap of the split bushing and the gasket gills are
horizontal (refer to
). Otherwise the hose
will be subjected to excess tension, which may reduce
its life time.
12. Tighten the piping connection flanges on both sides
of the pump.
13. Remove the crank cam from the motor shaft and
install the cover of the extended shaft or extra
cooling fan if applicable. (See Chapter 6.2.2)
14. Close the front cover and pour the correct amount of
LPP-T lubricant into the pump through the maintenance
window. For the correct amount of lubricant see
Appendix B.
15. Adjust the compression as instructed in Chapter 6.3.
16. Close the maintenance window and turn the
maintenance switch to on position.
Before electricity is connected to the pump make sure that
the crank cam is removed from the extended shaft and
the cover is installed back on the rotating shaft.
6.3 Adjusting the hose compression
Correct adjustment of the hose compression is the most
important factor affecting the hose life time.
The adjustment is based on adjustment with an eccentric
bushing.
The tightening torque values for the pump are given in
Appendix.
Always tighten the bolts in a crosswise sequence and
double check the make sure correct torque is reached.
When adjusting the hose compression, check the nearest
value from the table Appendix B for your application
1. Stop the pump so that the rotor remains in its topmost
position and turn the power off via the maintenance
switch. Lock the maintenance switch so that the pump
cannot be switched on during the maintenance work.
2. Open the transparent maintenance window.
3. Release the locking cover by turning its locking
screw(s) counter clockwise (refer to
Figure 22.
).
