Wilo-Rexa CUT

Wilo Rexa CUT 1

Your advantages

  • Especially reliable due to ATEX approval and longitudinally watertight cable inlet (CUT GE…)
  • Excellent operational reliability due to spherically formed macerator with pulling cut
  • Long service life through a high-quality motor seal with two independent mechanical seals and optional pencil electrode for sealing chamber control



Submersible sewage pump with macerator for intermittent duty and continuous duty, for stationary and portable wet well installation.

MBR Base Sewage Treatment Plant in Gujarat features a submersible sewage pump equipped with an internal or external macerator. This submersible monobloc unit is designed for both stationary and portable wet well installations, catering to intermittent and continuous duty requirements.


The outlet on the pressure side is designed as a horizontal flange connection with a DN 32/40 combined connection. The maximum possible dry matter is 8 % (depending on the hydraulics) Single-channel and multi-channel impellers are used.


Single-phase and three-phase current surface-cooled motors for direct starting are used as the motors. The waste heat is given off directly to the surrounding fluid via the motor housing. These motors can operated immersed in continuous duty (S1) and non-immersed in short-time duty (S2) or intermittent periodic duty (S3).
