Pump foundation
The foundation of a stationary centrifugal pump must be capable of absorbing the forces and torques transmitted to it by the pump without shifting its position (see Smooth running), in some cases it must also withstand forces transmitted by the associated drive and piping connected to the pump (see Pump nozzle load).
The foundation's strength and vibration behaviour (high-frequency-tuned and low-frequency-tuned pump foundation, see DIN ISO 10816-1) play a decisive role in ensuring its functional reliability.
Pump foundations and their characteristics
- A combined baseplate for the centrifugal pump and its drive is placed on a concrete foundation.
- Table foundations made of concrete or steel rest on special anti-vibration elements to achieve optimal vibration insulation against the environment (see Vibration). The individual components (gear unit, drive) are mounted on the table via individual baseplates or base frames (foundation frames).
A special pump foundation is not required if the baseplate is made of cast iron, steel or concrete and is built rigidly enough to prevent distortion (warping) so that small and medium-sized pump sets with moderate loads from the piping can be installed without a foundation (see Installation).
