The Nirolift is a standalone sump for below-ground use. It provides pumping from washing machines, sinks, dishwashers, showers, and bathtubs from buildings and areas below the sewer level in accordance with EN 12050-2.

• Globular shape for extra strength, with PP-30GF manhole cover featuring floor run-off and option of odour lock with aeration and venting.
• Universally adjustable in height and can be swivelled, thus allowing easy alignment with floor levels and tiling patterns, independent of the inflow or direction of the discharge lines. A 150 mm sump extension kit is available as an accessory.


• Optional submersible pump - selection determined by the intended application and by the volume of the medium. The pump either comes with a KS float switch or built-in level control. Please refer to product data sheet for more detailed specification.


• Two inflow ports DN 100 at 90º offset for DIN push-on connection. One port DN 70 for venting and use as a cable duct (supplied as standard with plug / cable inlet seal). One discharge port DN 40 with R 1¼" PVC female adaptor.
• Plastic cover for protection of the floor grating during installation work supplied as standard.
• Kit available as an accessory for sealing top of tank to damp-proof course.
• Suitable for use as a floor drain. Alternatively a stainless steel insert for fitting into the manhole cover to close and seal the run-off vent is available as an accessory.

Please note, attention to the backwash level is of vital importance for effective dewatering. All outflow points located below the backwash level must be protected against back flow according to standard EN 12056.
