5.3.1.2 Connecting the piping
DANGER
Impermissible loads acting on the flange of the duckfoot bend
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 without
transmitting any stresses or strains.
▷
Observe the permissible flange loads.
▷ Take appropriate measures to compensate for thermal expansion of the piping.
NOTE
When the pump set is used for draining low-level building areas, install a swing
check valve in the discharge line to avoid backflow from the sewer system.
CAUTION
Critical speed
Increased vibrations!
Damage to mechanical seals and bearings!
▷ Install a swing check valve in longer riser pipes to prevent the pump from
excessive running in reverse.
When fitting a swing check valve, make sure that the unit can still be vented
properly.
