The Challenger model series is a pump in a heavy, robust design with a directly flanged-on underwater motor for wet well installation.
For the surface-cooled design, the motor must be completely immersed in the suspension during operation.
The submersible motor pump benefits from our modular structure of the pump model series. The pump hydraulics essentially correspond to those of the HPK, NPK, NPW and KB models. Therefore, metallic and elastomer-lined pump types are available.
Their advantages:
- Extremely robust design
- Wet well installation possible depending on the type
