Installation and operating instructions SIE-DIE-PBE
• Pre-install coupling shells on the pump shaft with spacer discs
inserted in between and insert the pre-mounted coupling/shaft unit
carefully into the lantern.
• Pull a new mechanical seal onto the shaft. A commercially available
dishwashing liquid can be used as a lubricant.
• Install the impeller with washer and nut, countering at the impeller's
outer diameter while doing so. Avoid damage to the mechanical seal
due to jamming.
NOTE:
Comply with the screw tightening torque for the thread type (see the
following table "Screw tightening torques").
• Insert the pre-installed lantern unit carefully into the pump housing
and screw together. As you do so, hold onto the rotating parts of the
coupling to avoid damage to the mechanical seal. Observe the speci-
fied screw tightening torque.
NOTE:
For PBE pumps with ≤ 4 kW, the pump supporting foot must also be
reinstalled when screwing in the lantern unit.
• Slightly loosen the coupling screws. Slightly open the pre-installed
coupling.
• Install the motor using suitable hoisting gear and tighten the connec-
tion between lantern and motor.
NOTE:
Comply with the screw tightening torque for the thread type (see the
following table "Screw tightening torques").
• Slide the forked spacer (Fig. 5, Item 10) between the lantern and cou-
pling. The forked spacer must fit without any play.
• First, slightly tighten the coupling screws (Fig. 5, Item 1.41) until the
coupling half-shells are in contact with the spacer discs. Afterwards,
screw the coupling together evenly. In doing so, the specified dis-
tance between the lantern and the coupling of 5 mm is automatically
adjusted via the forked spacer.
NOTE:
Comply with the screw tightening torque for the thread type
(see the following table "Screw tightening torques").
• Remove the forked spacer.
• Install the pressure measuring lines of the differential pressure sensor.
• Install the coupling protection.
• Connect the power cables.
• Connect the module.
• Open the check valves in front of and behind the pump.
• Reset the fuse.
• Comply with the commissioning measures
(see Section 9 "Commissioning" on page 89).
