F 426

The Drum pump F 426 is ideal for mixing and pumping inhomogeneous liquids. You can keep liquids moving that tend to segregate, even during pumping, with the outlet closed. E.g., via a hand nozzle, the F 426 can be temporarily operated as a 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.

The practically achievable delivery rate is lower. It depends on the individual application, the fluid properties and the pump configuration.
