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: Conguration 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 ange.
Flow speed
Congure 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.
