Identify your pump model and then download the spare parts drawing to identify the exact part number you require. F 400 series pumps share many components, but o-rings, gaskets, impellers and bearings vary by pump type, material, length and diameter, so check carefully to ensure the correct spare part is selected.
FKM, NBR and FEP are o-ring materials. The correct choice depends on the pump model and the fluid being transferred, its concentration, temperature and contact time.
Because chemical resistance can vary with temperature and chemical concentration, customers should always check compatibility before ordering replacement seals. For additional guidance, use the Flux Chemical Resistance guide.
Mostly, but not always. Most F 400 series pumps can be specified with interchangeable, axial or semi-axial impeller designs, constructed from ETFE (or sometimes stainless steel) material. However, always check pump diameter, model type and spare parts drawings before selecting a replacement impeller. Alternatively, contact us for further guidance.
These Flux Drum Pump Parts keep your F 400 series pumps running smoothly, reduce downtime and also extend service life. Explore Flux pump accessories or find out more about our drum pumps here. Also please do contact us if you require further assistance.
