2. Always flush and clean the pump, particularly if it has been used for handling
noxious, explosive, hot or other hazardous fluids.
3. If the fluids handled by the pump (set) leave residues which might lead to
corrosion damage when coming into contact with atmospheric humidity, or
which might ignite when coming into contact with oxygen, the pump set must
also be neutralised, and anhydrous inert gas must be blown through the pump
for drying purposes.
4. Always complete and enclose a certificate of decontamination when returning
the pump (set).
Always indicate any safety and decontamination measures taken. (⇨ Section 11

The lifting unit is provided with several horizontal inlet nozzles (1). The pump (4)
pumps the fluid handled into the vertical discharge line (8).
The fluid to be handled flows into the lifting unit through horizontal inlet nozzles (1)
and is collected in a gas-, odour- and water-tight plastic tank (7). When the level
sensor detects a defined fill level, the fluid is automatically pumped off to a level
above the flood level and towards the public sewer by either one or two pumps (4).

Permissible
fluids
4 Description
18 of 56 Compacta - Amarex N/KRT

‒ animal faeces together with the necessary flushing water as well as stormwater in
case no other way of disposal is possible. 3)
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.
