Wilo-Rexa FIT-S

The Wilo‑Rexa FIT‑S is a submersible sewage pump variant from the Rexa FIT series, equipped with a float switch for automatic level‑controlled operation. It combines the robust design of the Rexa FIT with convenient automatic switching, making it ideal for domestic and municipal wastewater pits where reliable, unattended operation is required.

Description

The Wilo-Rexa FIT-S03 grinder pump ensures reliable pressure drainage in accordance with EN 12050-1 in commercial applications. The radial macerator with double shear effect reliably shreds the solids. Clogging is prevented and safe operation is ensured. In addition, the overall costs are significantly minimised. Firstly, the optimised hydraulics provide a high degree of efficiency along with the maximum delivery head. Secondly, the smallest possible pipework can be connected. The high-quality stainless steel motor is light and easy to maintain. On the other hand, the motor is extremely corrosion-resistant, even when the motor is non-immersed. A high-quality seal with two mechanical seals ensures a long service life.

  • Float switch control: Automatic on/off operation based on water level.
  • Robust construction: Cast‑iron housing with corrosion protection.
  • Free‑flow impeller: Handles sewage with solids up to ~50 mm.
  • Flexible installation: Suitable for stationary wet‑well setups or portable use.
