Pumping units for sewage water
KSB manufactures a large selection of different plastic pumping units for pumping drainage and sewage water.
In general, manufactured pumping units can be divided in two types – pumping units to be installed inside a building and pumping units to be installed outside a building.
Pumping units to be installed inside a building
Smaller pumping units of KSB products for installation inside a building are supplied with the Ama-Drainer-type drainage pump, and they supposed to be installed under the floor in a building basement. Such pumping units are capable of pumping the so-called gray water from saunas, laundries, washing machines, pools, etc.
Ama-Drainer box

Capacity (Q) | max. 24 m³/h |
Head (H) | max. 6,5 m |
Temperature | max. 35ºC |
Larger pumping units for installation inside a building belong to the series
Mini-Compacta and
Compacta.

Such pumping units are capable of pumping wastewater, as they are equipped with one or two wastewater pumps with a dry location, where the impeller can be either single-gear, free-flow or with a crusher.
If a model is selected with a single-gear or a free-flow impeller, the throughput capacity of a smaller model is 80mm therefore risk of clogging is brought to minimum.
Pumping units are fully air-tight and provided with all necessary automation, there is an electrical board in the set of pumping units with two pumps; models (smaller) with a single pump do not need a separate board. To install, it is only necessary to connect pipelines to a pumping unit+air pipe and connect to a power network.
As additional backup, it is possible to install alarm, which controls if, for some reason, one pump does not start or is clogged.
Capacity (Q) | max. 135 m³/h |
