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 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 in
horizontal position, as showed in figure 1. 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 pump 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 and the pump should not be in direct
contact with any objects. Pump seals prevents dust and particles from entering as prescribed by IP class. Make
sure that the distribution box cover is mounted and that the 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.
Misconnection or overload could cause pump shutdown or even permanent damage.
•
Pumps might be heavy. Provide yourself help if needed,
•
Pump must not be used in the safety pipelines,
•
Pump should not be used as a holder during welding!
•
When reassembling, care should be taken to ensure seal fit. Failing that, water could
•
cause damage to pumps internal parts,
Drains between pump motor housing and hydraulic housing must be left free (should
•
not be thermally insulated), as it could interfere with cooling and condense drainage
(figure 1 ) ,
Hot medium can cause burns! The motor can also reach temperatures that could cause
•
injury.
Motor hosuing should not be termo isolated
