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 fig. 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 positions shown in fig. 2 and 3). Pump head
is mounted to hydraulic casting with four screws. By unscrewing those, the pump head can then be turned (fig. 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.
• 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
pump internal parts,
• Drains between pump motor housing and hydraulic housing must be left free (shouldn't be thermally
insulated), as it could interfere with cooling and condense drainage,
• Hot medium can cause burns! The motor can also reach temperatures that could cause injury.
