Installation example with a metal riser (pipes)
ü The safety regulations have been observed. (ð Section 5.1, Page 25)
ü Suitable lifting equipment for the total weight has been selected and is on hand.
(ð Section 5.2.6, Page 30)
ü The motor fill has been checked and topped up if required.
ü Extension cables have been properly connected to the power cable, measuring
cable and control cable.
ü The pump set has been placed in a horizontal position in a level assembly area
and is protected against rolling off.
ü Cable ties to securely fasten the power cable, measuring cable and control cable
are available.
ü A sealing agent is available.
ü A mounting plate, pairs of supporting clamps and beams have been selected for
the total weight (ð Section 5.2.6, Page 30) and are on hand.
ü Risers with recesses in the flanges
1. For flanged risers:
Bolt the first pipe section (max. length 2 m) to the connection branch. Fasten
the mounting plate to this pipe section.
2. Fasten the first pair of supporting clamps below the upper flange.
NOTE
On threaded risers fit an anti-rotation device to prevent the pump set from
unscrewing itself from the threaded riser during start-up.
1. For threaded risers:
Screw the first pipe section (max. length 2 m) with sealing agent applied into
the connection branch. In addition, secure it with the two locking screws
supplied. For this purpose, drill a shallow hole into the threaded end of the pipe
section, taking care not to drill through the threaded end. Insert the locking
screws with thread-locking compound in such a way that their tips rest lightly
but do not press on the threaded pipe end. Allow time for the sealing agent to
cure. The connection is now sufficiently secured against loosening.
2. Use cable ties to attach the power supply cable as well as any control and
measuring cables to the riser approximately 0.5 m above the lower flange.
(ð Section 5.3.1, Page 36)
3. Place two sturdy beams across the well opening.
4. Pull the pump set into upright position with the lifting equipment.
5. Attach the pump set to the crane hook (e.g. mobile crane) by the mounting
plate and lower it into the well until the first pair of supporting clamps rests on
the beams.
6. Remove the mounting plate and fasten it to the second riser.
7. Fasten the second pair of supporting clamps to the second riser.
8. Use the lifting equipment to lower the second riser onto the first riser, and
install it.
9. Undo the first pair of supporting clamps and lower the pump set until the
second pair of supporting clamps rests on the sturdy beams.
10. Repeat these steps for every pipe section, lowering the pump set into the well
until the installation depth H
