Volute Liner

Stationary casing liner that forms the pressure chamber and protects the pump body from abrasive wear.

What it does

The volute liner converts kinetic energy from the impeller into pressure head while containing the slurry. It is the second-highest wear component after the impeller and must match the casing geometry exactly.

Material options

  • High-chrome white iron A05 / A07 — for heavy abrasive mill discharge and cyclone feed.
  • Rubber R55 / R26 — for corrosive duties and lower-impact abrasion.
  • Ceramic-rubber composite — added where both impact and sliding abrasion are present.

Manufacturing & quality

Volute liners are cast, heat-treated and machined to match the original casing throat and cut-water dimensions. Dimensional checks are carried out before shipment to confirm drop-in fit.
