The TECMA SaniSplit NK 3 is a compact, automatic grey/black-water transfer unit for showers, washbasins, and bidets. A pressure-switch triggers a powerful, low-noise centrifugal pump as soon as water enters the internal tank. The patented split design lets you remove the pump/pressure-switch module from the fixed collection tank in seconds for clean servicing, while a non-return valve prevents backflow. Rated IP55, with 2× DN40 inlets, 1× DN40 outlet, 270×470×175 mm footprint, 8.0 kg weight, and support for up to 3 appliances, the SaniSplit NK 3 is offered in 12V, 24V, and 230V variants and has been trusted in the marine market for 15+ years.
