Drivers
AxFlow Aturia NA series pumps may be driven by an electric motor through a shaft -to-shaft coupling.
There are particular points which can affect the pump:
Shaft -to-shaft flexible couplings must be properly aligned, as poor alignment will
cause high loads on the pump bearings. Couplings must be suitably rated, and provide
sufficient flexibility to prevent shock forces and oscillating loads from being
transmitted to the pump shaft. This is particularly important for diesel engine drives.
When designing the drive system and prime mover, take into account that the pump
dismantles by removing the rotating element out from the back of the pump casing.
Sufficient space should be allowed to facilitate dismantling of the pump.
