Bredel 50 spare parts: frequently asked questions
Tap a question to see the answer.
What are the wear parts on a Bredel 50 hose pump?
The hose element is the main wear item. Other wear and consumable parts on the list are the pressing shoes (aluminium, or epoxy with a stainless insert), the shims that set hose compression, hose lubricant in 10 L cans, the wear ring and the bearings.
Which hose materials are available for the Bredel 50?
The Bredel 50 hose element is listed in natural rubber (metering or transfer duty), NBR, food-grade NBR, fluorinated nitrile (F-NBR), EPDM and CSM/Hypalon. Choose the material to suit your fluid. If you're not sure what's fitted, send us your nameplate and we'll confirm.
Can I use Bredel 40 or 65 parts on a Bredel 50?
Don't assume so. The Bredel 40 to 100 share one OEM manual (m-bredel-40-100-en), but this page lists the Bredel 50's own order codes; for example, the NBR hose element is 28-050040. Order against your exact model, or send a nameplate photo and we'll check. See the Bredel 40 spare parts page for the smaller size and the Bredel 65 spare parts page for the next size up.
Are other Bredel 50 parts available beyond this list?
Yes. The page shows the most-ordered parts. Brackets, fasteners, the breather, the revolution counter and heavy-duty options are available on request. Tick the parts you need, add any extras in the quote form, and we'll confirm the correct parts before quoting. Browse all Watson-Marlow Bredel spare parts.
