4.7 Fluids handled
WARNING
Pumping of impermissible fluids
Hazardous to persons and the environment!
▷
Only discharge permissible fluids into the public sewer system.
▷
Check the suitability of pump/system materials.
Variant A (standard design)
Permissible
fluids
According to DIN 1986-3 the following fluids can be discharged into sewer systems:
Water contaminated by domestic use, human and - as far as required and permitted -
animal faeces together with the necessary flushing water as well as stormwater in
case no other way of disposal is possible.
5)
Impermissible
fluids
Substances / water which must
not
be discharged into the sewer system are, amongst
others:
Solid matter, fibres, tar, sand, cement, ash, coarse paper, paper towels, cardboard,
debris, garbage, offal, grease, oil.
Waste water from installations situated above the flood level (EN 12056-1).
Waste water containing hazardous substances (DIN 1986-100), e.g. greasy waste
water from large-scale catering kitchens.
For drainage of greasy water a grease separator to DIN 4040-1 must be fitted.
Variant C for aggressive fluids
Additional permissible
fluids
In addition to the fluids approved for the standard variant, this lifting unit is also
suitable for handling aggressive fluids:
Waste water, e.g. from heat recovery systems
Waste water from swimming pools (increased chlorine concentration)
Waste water with salt content (e.g. seawater)
4.8 Collecting tank
The collecting tank is designed for unpressurised operation. The waste water is
stored in the tank in unpressurised condition and is then pumped into the sewer
system. The table below indicates the effective tank volume as a function of the inlet
nozzle level H in millimetres.

Other types of waste water, e.g. industrial waste water, must not be discharged into the local sewer system without prior
treatment.
