The Flux Pumps JUNIORFLUX F 314 Sealless Drum Pump is suitable for pumping comparatively small quantities out of containers such as canisters or drums of up to 200 liters. The small outer tube diameter makes it possible to pump out of narrow openings.

This sealless drum pump transfers the medium from the rotor along the shaft into the inner tube to the outlet. In the inner tube, the medium has the same level as in the container. When emptying it flows off via the relief openings. 

The JUNIORFLEX motor and pump tube are fixed with screws and includes a mains connection to enable very long operating times. An overload cut-out switch prioritizes high operational safety, and the pump can be single-handedly operated.
