1. Handling and intermediate storage

1.1

Handling

• Always take the weight and centre of gravity into
consideration.
• Never use the motor eye bolts when slinging as-
sembled pump sets.
Examples for transport of pump unit:
1.2

Unpacking

Check that the delivery is complete and undamaged. Any miss-
ing parts or damage must be confirmed by the carrier on the
original freight note and reported to us immediately.
1.3

Intermediate storage

• Seal the suction and delivery branches, using closure caps,
plugs or blank flanges.
• Store in dry, dust free conditions protected from frost or ex-
cessive heat.
• Turn the rotating assembly on the shaft or coupling a few
times every 2 weeks and leave in a different angular position.
• Long-term storage (over 3 month) preservation required.
• Long-term storage (over 2 years) renew the lubricants before
installing the pump.

Preservation

If requested, we will preserve your pumps before delivery or at
site. Please contact our service department.

Construction

Proper handling
Please refer also to the sectional drawings in paragraph 7.4.
2.2.1
The pump casing is equipped with a suction side wearing ring.
On discharge side, the casing cover is the wear part. At disas-
sembly of motor, mechanical seal, impeller and pump shaft the
casing stays in the piping (process construction).
Improper handling
2.2.2
The pumps are equipped with closed radial impellers. For some
pump sizes alternatively Vortex impellers (.F) or two-channel
impellers (.Z) are available.
2.2.3
For pumps with IEC standard motor (execution B) the pump
shaft is connected via a rigid coupling to the motor shaft. For
pumps with special motors (execution BS) the impeller is direct-
ly mounted to the extended motor shaft. The direct-coupled mo-
tor is bearing the pump part.
2.2.4
The fitted shaft sealing arrangements are described in detail in
the contract documentation.
A constant venting of the mechanical seal area has to be en-
sured.
