Pump installation

4.1

Installation into pipe lines

Pump is protected with a double box during transport. It can be lifted from the
box with internal handles or by lifting it by the heat sink.
Pumps are designed to be built in connecting flanges, using all screws. The
connecting combined flanges are designed so the pump can be installed in
PN6 or PN10 nominal pressure pipelines. Because of the combined flange
design, washers must be used on the pump side, when installing the pump.
For a pump to operate with minimal vibrations and noise it should be installed
into pipe lines with its axis (1-1) in horizontal position, as showed in
Pipes should be without curves for at least 5-10 D (D = rated pipe diameter)
from the flanges.
Desired head orientation can be achieved by rotating the pump head (allowed
positions shown in figure 2 and 3). Pump head is mounted to hydraulic
casting with four screws. By unscrewing those, the pump head can then be
turned (figure 4).
Ambient around the pump should be dry and illuminated as appropriate.
Pump seals prevent dust and particles from entering as prescribed by IP
class. Make sure that the distribution box cover is mounted and that cable
glands are tightened and are sealing.
Pump will provide the longest lifetime with ambient at room temperature and
moderate medium temperature. Prolonged operation at elevated temperatures
could increase wear. Aging is accelerated by high power and high temperatures.
