17.6 Pipelines

Use seamless precision steel pipes in accordance with DIN 2391 and removable 
pipe connections.

Pressure in the suction nozzle

The permitted pressure values at the suction nozzle of the pump must be maintained 
(chapter 5.2).

Fig.

 17.6: Configuration of the pump suction piping

If the suction cross-section needs to be adjusted in the suction nozzle (e.g. in the 
case of higher viscosity) in order to achieve the permitted pressure, this must be 
carried out immediately before the suction flange.

Flow speed

Configure the suction piping cross-section as follows:
•  Flow speed 1 m/s (in suction mode) (cavitation!)
•  • Flow speed 1.5 m/s (inlet with slight overpressure) 

 

Note the permitted input pressures in chapter 5.2.
