Wilo-Rexa FIT-S Commercial lightweight sewage pump with blades to prevent blockage, electrophoretic layer stainless steel pump body to prevent corrosion
Efficient submersible sewage pump in non-clog design with macerator for reliable pressure drainage in commercial properties The Wilo-Rexa FIT-S grinder pump ensures reliable pressure drainage in accordance with EN 12050-1 in commercial applications. The radial macerator with double shear effect reliably chops 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.
Your advantages Excellent anti-clogging reliability due to radial macerator with double shear effect Optimised hydraulics/macerator combination for a wide coverage of delivery head Low overall installation costs thanks to the use of smallest possible piping Designed for an easy selection covering the needs of various building types Long service life due to high-quality motor with two mechanical seals and optional sealing chamber monitoring High corrosion resistance, even with non-immersed motor, thanks to stainless-steel motor housing
