NOTE
Installing check and shut-off elements in the system is recommended, depending on
the type of plant and pump. However, such elements must not obstruct proper
drainage or hinder disassembly of the pump.
ü
The nominal diameters of the pipelines are equal to or greater than the nominal
diameters of the pump nozzles.
ü
To prevent excessive pressure losses, adapters to larger diameters have a diffuser
angle of approx. 8°.
ü
The pipeline is anchored in close proximity to the discharge flange and
connected without transmitting any stresses or strains. Its weight must not be
carried by the pump discharge flange.
1. Thoroughly clean, flush and blow through all vessels, pipelines and connections
(especially of new installations).
5.4.2 Permissible forces and moments at the pump nozzles
Fig. 11:
Forces and moments at the pump nozzles
The data on forces and moments apply to static piping loads only. The values are only
applicable if the pump is installed on a baseplate and bolted to a rigid and level
foundation.
