3.2 Shaft Sealing
Pumps of design ICB are exclusively sealed with
single mech. seals with installation dimensions acc. to
EN 12756 (DIN 24960), design "K", form "U".
Two shaft sealing variants are available. On the data
sheet and / or the order confirmation the kind of shaft
sealing is given. An instruction for the mounting and
operation of mech. seals is contained in the particular
"Mounting Instruction of Shaft Sealing".
For nominal size (d

The mech. seal used in the standard design is
not resistant to mineral oils.
For further details about mech. seals, as well as
the dangers of accidents, connected to them
refer to chapter 6.6 and chapter 7.2.
3.3 Bearing
The shaft is guided by the ball bearings of the motor.
The bearings are grease lubricated for life and,
therefore maintenance-free.

measured in 1 m distance
from pump surface acc. to DIN 45635, part 1 and 24.
Room and foundation influences are not considered.
The tolerance for these values is
±3 dB(A).
Addition with 60 Hz-operation:
Pump alone:
−
Pump with motor: +4 dB(A)
3.5 Permitted Nozzle Loads and Torques
at the Pump Nozzles ...
... following the Europump-Recommendation for
pump acc. to ISO 5199.
The data for forces and torques are only valid for
static piping loads.
All values for forces and torques refer to standard
materials EN-GJS400-18LT and 1.4408.
