JUNIORFLUX F 310 with fixed commutator motor and mechanical seal is suitable for a wide variety of applications, from emptying smaller containers up to 200 litre barrels. This pump should be selected when solid particles are present, or if the liquid has a tendency to crystallise. The mechanical seal eliminates premature bearing wear, as particles cannot enter the inner tube. This design can also be selected if the pump is to be used with several different liquids - the sealed inner tube minimises risk of cross-contamination.
