Overview

The F 426 drum pump (with mechanical seal to cover inner tube; immersion length 1200 mm) is ideal for mixing and/or pumping inhomogeneous media. Media, which are prone to rapid separation, can therefore be kept in motion even during the pumping process. If the outlet is closed, e.g. by a pump nozzle, the F 426 drum pump can also be temporarily run as a pure mixing pump. The transition between "Mix" and "Pump" is performed very easily by turning an adjusting lever. There are two adjusting levers for opening and closing the mixing apertures with ease. The mixing apertures allow the medium to flow back into the container for mixing. The drum pump is easy to disassemble for cleaning. The drum pump is made from stainless steel and can also be used in areas subject to explosion hazards for liquids with an electrical conductivity of more than 10,000 pS/m. If necessary, the pump assembly can also be combined with different motors.

Benefits

The operating mode can be changed during operation
Easy to dismantle for cleaning
Can be operated temporarily against a closed valve (pump nozzle, ball cock, etc.), up to stated max. operating temperature
Stainless steel version also for use in areas subject to explosion hazards
