Backflow
Waste water flowing back from the sewer into the
connected drainage piping
Certificate of decontamination
A certificate of decontamination is enclosed by the
customer when returning the product to the
manufacturer to certify that the product has been
properly drained to eliminate any environmental
and health hazards arising from components in
contact with the fluid handled.
Close-coupled design
Motor directly fitted to the pump via a flange or a
drive lantern
Discharge line
Pipe for transporting waste water to a level above
the flood level into the sewer system
EN 12050-2
European Standard for waste water lifting units
which are used to dispose of faeces-free waste
water occurring below the flood level of buildings
and sites. It defines general requirements as well
as principles of construction and testing.
Flood level
Maximum backflow level of waste water in a
drainage system
Hydraulic system
The part of the pump in which the kinetic energy
is converted into pressure energy
Pump
Machine without drive, additional components or
accessories
Pump set
Complete pump set consisting of pump, drive,
additional components and accessories
Submersible motor pump
Submersible motor pumps are floodable, close-
coupled units which are not self-priming. The
pumps are usually operated completely
submerged. They may be operated outside the
fluid for short periods of time, until the minimum
fluid level has been reached.
Waste water
Water consisting of a combination of water
discharged from households, industrial and other
businesses as well as surface water.

5 Discharge nozzle 10 Suction nozzle
Design The pump is designed with a vertical fluid inlet and a vertical outlet. The hydraulic
system sits on the extended motor shaft. The shaft runs in common bearings.
Function The fluid handled enters the pump axially via the suction nozzle (10). The rotating
impeller (6) accelerates the fluid handled outward. In the flow passage of the volute
casing (8) the kinetic energy of the fluid handled is converted into pressure energy
and the fluid handled is pumped to the discharge nozzle (5). The fluid handled leaves
the pump via the discharge nozzle.
At the rear side of the impeller, the shaft (2) enters the hydraulic system via the
volute casing (8). The shaft passage through the volute casing is sealed to
atmosphere with two bi-directional shaft seals (4) in tandem arrangement. A
lubricant reservoir between the seals ensures cooling and lubrication of the shaft
seals. The shaft runs in rolling element bearings (1) and (3).

5.4 Connecting the piping
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.
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.
NOTE
The highest point of the discharge line must be above the flood level (usually street
level) to prevent any backflow from the sewage system.
Stationary installation
