Slurry Pump Liner Material Selector

Find the right wet-end material for your particle size, pH, and application in under 30 seconds — based on peer-reviewed wear literature.

Selection logic is based on the d85 ~700 µm threshold established by Walker & Robbie, Wear 302 (2013), Elsevier — the most widely cited slurry pump wear study in peer-reviewed literature. Results are engineering guidelines; confirm with BBP for your exact duty point.

Particle Size — d85 (µm)

d85 = particle size where 85% of particles are finer than this value

Slurry pH

Solids Concentration (%w/w)

Application Type

Don’t know your d85? If you have a particle size distribution (PSD), d85 is the size at which 85% of particles by weight are finer. Common references: flotation concentrate ≈ 75–150 µm; fine tailings ≈ 150–400 µm; cyclone feed ≈ 1–5 mm; mill discharge ≈ 2–20 mm; dredge sand ≈ 5–50 mm.
