Glossary
Backflow
Waste water flowing back from the sewer into
the connected drainage piping
Cavitation damage
Material of the pump internals is destroyed by
imploding vapour bubbles.
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.
