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.
