Auxiliary Connections - KSB WKLn Installation & Operating Manual

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.
CAUTION
Incorrect earthing during welding work at the piping
Destruction of rolling element bearings (pitting effect)!
▷ Never earth the electric welding equipment on the pump or baseplate.
▷ Prevent current flowing through the rolling element bearings.
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.
