5.4 Piping
5.4.1 Connecting the piping
DANGER
Impermissible loads acting on the pump nozzles
Danger to life from escaping hot, toxic, corrosive or flammable fluids!
▷ Do not use the pump as an anchorage point for the piping.
▷
Anchor the pipes in close proximity to the pump and connect them properly
without transmitting any stresses or strains.
▷ Observe the permissible forces and moments at the pump nozzles.
▷ Take appropriate measures to compensate for thermal expansion of the piping.
NOTE
Installing check and shut-off elements in the system is recommended, depending on
the type of plant and pump. However, such elements must not obstruct proper
drainage or hinder disassembly of the pump.
ü Suction lift lines have been laid with a rising slope, suction head lines with a
downward slope towards the pump.
ü A flow stabilisation section having a length equivalent to at least twice the
diameter of the suction flange has been provided upstream of the suction flange.
ü
The nominal pipe diameters are at least equal to or larger than the nominal
pump nozzle diameters.
ü Adapters to larger nominal diameters are designed with a diffuser angle of
approx. 8° to avoid excessive pressure losses.
ü The pipes have been anchored in close proximity to the pump and connected
without transmitting any stresses or strains.
1. Thoroughly clean, flush and blow through all vessels, pipes and connections
(especially of new installations).
2. Before installing the pump in the piping, remove the flange covers on the
suction and discharge nozzles of the pump.
3. Connect the pump nozzles to the piping.
