  • .

The F426 is ideal for mixing and/or pumping fluids that have a tendency to settle out or separate over time, even during pumping. With the outlet closed, e.g. via a hand nozzle, the F426 can be temporarily operated as pure mixing pump. By turning the adjusting lever, the pump can be easily adjusted to "mixing" or "pumping". The pump is easy to dismantle for rapid cleaning. The pump is available in stainless steel and polypropylene. The stainless steel version can also be used in hazardous areas.
