4.3 Design details
4.3.1 Drive
The electrical data is given on the name plate. Motor design to
DIN/VDE 0530 Part 1/IEC 34--1, thermal class F, enclosure IP
68 for the complete pump in acc. with DIN VDE 0470 Part 1 and
IP 58 for the electrical equipment in acc. with DIN/VDE 0530
Part 5 (EN 60 034, EN 60 034--1), d.o.l. starting.
4.3.2 Shaft seal and bearings
-- Shaft sealing is effected by means of a (product--side) mech-
anical seal and (motor--side) shaft seal ring. An oil reservoir
between the shaft seal ring and the mechanical seal provides
cooling and lubrication.
-- The pump is equipped with maintenance--free rolling element
bearings.

5. Installation at site

5.1 Safety regulations

The pump must be earthed and protected by a 30 mA resid-
ual current device to IEC 364/NFC 15 100.
It is not permitted for any person to enter the tank unless
special safety precautions habe been taken in accordance
with current safety regulations.
5.2 Checks to be carried out prior to installation and
commissioning
All structural work required must have been prepared in accord-
ance with the dimensions stated in the dimension table
(p. 68--69).
The concrete foundations shall have sufficient strength to
ensure safe and functional installation (min. 32.5 N as per EN
197--1 or equivalent standard).

5.3 Installation of the pump

Prior to installation, inspect the pump set and the electric cables
for damage. Make sure that there is no foreign matter inside the
pump. Make sure that the impeller turns smoothly.
5.3.1 Verification of operating data
Prior to installation the data on the name plate shall be checked
against the purchase order data and system data.
To avoid overloading of the motor, it is recommended to operate
the pump at H/Q data in the middle section of the characteristic
curve.
5.3.2 Transportable model
Description
Transportable pump models are fitted with pump feet.
The lifting chain / rope must be attached on the same side as the
discharge nozzle.
The pump shall always be placed in vertical position (motor on
top) and on solid ground.
(See dimension tables, p.
transportable Ama- -Porter pumps, provided with the installation
parts for transportable models).
5.3.3 Stationary version
Description
A guide arrangement enables the pump to be lowered into the
sump or tank, where it attaches itself automatically to the duck-
foot bend which has been fitted to the floor. A joint ring between
the pump and the duckfoot bend and the weight of the pump
itself achieve a tight connection.
The lifting chain / rope must be attached on the same side as the
electric cable.
(See dimension tables, p.
stationary submersible motor pumps provided with the installa-
tion parts for stationary models).
5.4 Connecting the piping
See dimension tables, p. 68--69.
Connect the discharge pipe to the pump without trans-
mitting any stresses or strains.
Never use the pump and the duckfoot bend as an anchorage
point for the pipeline.
Thermal expansions of the pipelines must be compensated by
appropriate measures so as not to impose any extra loads on
the pump exceeding the permissible pipeline forces and
moments.
Danger to life when toxic or hot fluids are handled!
A swing check valve shall be fitted in long riser pipes, in
order to prevent drainage of the discharge line after the pump is
switched off. Choose the position of the swing check valve so
that the sump can still be properly vented.
5.5

Connection to power supply

Connection to the power supply must be effected by qualified
specialist personnel only.
Compare the mains voltage available against the voltage
stated on the name plate.
Observe relevant local regulations.
Connection of electric cable (extension):
-- The cross--section of the extension cable must be at least
equal to that of the pump cable.
-- The cable extension and connection points must be pro-
tected against moisture.
