5. Installation
Always refer to the local or national regulations and codes relating to the selection of the installation site, the water and power
connections, etc.
5.1 Position
Pumps should be installed in a protected environment – not exposed to weather.
Make sure that there are no obstructions to prevent proper motor cooling.
5.2 Anchoring
The pump must be secured to a solid foundation by bolts through the holes in the flange or base plate.
An illustration of page 10 shows the bolt location and the pipe connections.
5.3 Installation example
When positioning and installing the pump, follow the installation examples in order to avoid damaging the pump.
Pos. Description
1
Pipe support: Support piping system properly to avoid stresses on connections.
2
On-off valves: Install on-off valves for easy access- before the pump intake and after
the pump discharge.
3
Use flexible piping on both input and output sides of the pump to reduce vibration and
transmission of noise.
4
Check valves will prevent return flow of pumped liquid when pump is stopped, reducing
the danger of pump damage.
5
Control Panel: Use high quality components. Make sure that the panel conforms to
local standards and regulations.
6 Do not place elbows next to the pump intake and discharge.
7
If pump needs to be operated with on-off valve closed, install a by-pass line to avoid
damaging the pumping system.
