Why are flexible couplings generally chosen for sewage pumps? Such as elastic pin couplings, claw couplings, etc
The same is true for the others. Reduce the impact of vibrations and pipes.
Not only sewage pumps, but also many other pumps that are not directly coupled should use flexible couplings in order to reduce the forces acting between the pump and the drive unit. Since there is no precise alignment of the relative positions between the pump and the drive unit, flexible couplings can compensate for such errors
Flexible couplings serve a compensatory function, reducing vibrations
Since the speed of this type of pump is not high, the compensation provided by the flexible coupling is significant, resulting in low vibration; moreover, the bearings inside the equipment are less likely to get damaged
Centrifugal pumps are generally connected in a flexible manner; rigid connections are only seen in vertical pumps, while horizontal pumps all have flexible connections
