Bredel 80 spare parts: frequently asked questions
Tap a question to see the answer.
What spare parts are listed for the Bredel 80?
The list covers hose elements in seven materials, aluminium or epoxy pressing shoes, shims, Bredel hose lubricant, the wear ring and bearings, seals and gaskets, the rotor, drive shaft, housing, hub, cover and inspection window, plus hose inserts in 316 stainless, PP, PVC or PVDF, hose clamps and flanges.
Which Bredel 80 hose material do I need?
Hose elements are listed in natural rubber (metering or transfer duty), NBR, food-grade NBR, fluorinated NBR, EPDM and CSM. The hose is the wear item, so the material must suit your fluid. Tell us what you pump on the quote form and we'll confirm.
Why is my Bredel 80 overheating?
The troubleshooting guide lists a low lubricant level or incorrect shim adjustment. Top up with Bredel hose lubricant (28-904143) or adjust the shims, which set hose compression. Running too fast or too hot also shortens hose life.
How do I make sure I order the right Bredel 80 parts?
