4.7. Piping
The piping must meet the following requirements:
General
⚫ Ensure the piping is sufficiently supported, especially besides the inlet and outlet ports. The
piping should be fully supported independently from the pump.
⚫ The connections must be fitted square to the pump.
⚫ The lines must be fitted and connected stress-free.
! Piping which is fitted obliquely, insufficiently supported or exerting force to the pump,
may cause serious damage to the pump!
⚫ Check if the piping shows any visible leakage.
Inlet piping
⚫ It is recommended to place the pump below the supply liquid level. A flooded suction
reduces the presence of air in the system.
Non-return valves
⚫ In case the pump is installed above the supply liquid level fit a non-return valve to the foot of
the suction line to keep it filled with liquid. This applies especially when low-viscous liquids
are conveyed.
