4.2 HYDRAULIC INSTALLATION INTO SYSTEM
The pump is designed to be installed into the pipework only in certain orientation, this is to avoid any air to be trapped
inside the pump and risk of damaging the bearings or overheating the pump.
Fig.3
To ensure the pump delivers the required flow and pressure, the pipework designer should also consider a minimum
length of pipwework to be straight (without bends) for 5-10 D (D = rated pipe diameter) from the flanges on the inlet
and the outlet side of the pump.
Ambient environment 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 in the pump as per the IP class
rating. Make sure that the distribution box cover is mounted properly and that the cable glands are tightened and are
sealing.
The Pump will provide the longest lifetime with ambient temperature within the limits specified and moderate medium
temperature. Prolonged operation at elevated temperatures could increase wear. In general, aging of any rotating
machine is accelerated by high power and high temperatures.
