Reliable, Efficient, New - the next generation of waste water pumps

The new generation of waste water pumps: in combination with non-clogging impellers and high-efficiency KSB motors, the Amarex KRT and Sewatec type series offer even better overall efficiency.

The next generation of waste water pumps

Reliable and efficient: the new non-clogging impeller

F-max impeller F-max impeller

Maximum efficiency, minimum clogging risk due to the asymmetric arrangement of its vanes, the free-flow impeller F-max offers a large, free passage that allows solids of different sizes to pass without difficulty. Moreover, the slightly convex profile of the hub in the middle of the impeller reliably prevents all risk of clogging from long-fibrous materials such as hygiene wipes.


Customized pumps for every requirement

Besides specially adapted impellers and energy-efficient motors, KSB offers a wide range of installation types as well as a large choice of materials. So the best solution is available for each application – for optimum efficiency and operating reliability.

Wet installation

Submersible motor pumps are used in pumping stations requiring wet-installed pumps and are located directly in the pump sump. Separate machine rooms are not needed. As a result, the planning and investment costs for the pumping station building itself are correspondingly low. For wet installation, a lifting chain or a rod system are used to lower the submersible motor pump into its final installation position and lift it out again as necessary. Monitoring sensors are fitted to the submersible motor as standard in order to prevent any water or moisture from entering the motor.

Installation in machine rooms

With dry installations, the pumps are located in the dry area of the machine room and the pumps are directly accessible. Maintenance work is performed under more hygienic conditions than with wet installation, as only the inside of the pumps comes into contact with the fluid handled. In addition, the pump can be fitted with sensors for pump monitoring and planning maintenance work. Combined with IE4 electric motors and by operation on frequency inverters, a very efficient level of operation can be achieved.

Long life and high operating reliability with the right material for each application

KSB's materials laboratory develops and continuously improves special wear-resistant materials. These are extremely resilient to corrosive and abrasive waste water. From these materials our foundry staff produce highly durable components that can withstand adverse conditions for many decades, providing an important basis for minimizing the costs of waste water transport in the long term.
Materials such as cast iron, stainless steel (duplex steel) and particularly wear-resistant white cast iron used in KSB's waste water pumps make for optimum protection, even from industrial waste water, and ensure trouble-free operation.
