Lime Slurry — Equipment Material Selection

Direct answer: This page collects every published row in the LibertyCES datasets that applies to lime slurry service: Flowline chemical compatibility chart, elastomer seal compatibility, centrifugal pump material resistance, peristaltic tube compatibility, engineering rules. Rows are listed under the dataset's own names (calcium hydroxide, milk of lime, lime slurry). The datasets rate these as chemicals; solids loading and slurry abrasion are covered by the engineering rules below, not by the compatibility ratings. LibertyCES supplies the equipment for handling these fluids, never the fluid itself.

Engineering Rules That Apply

Crystallizing Slurry No Valves Seals

Crystallizing/hardening slurry is a chemistry/mechanics mismatch, not an undersized-pump problem. Single-roller peristaltic hose pumps have no valves, seals, or glands in the fluid path for the chemical to crystallize in.

Confidence: confirmed. Source: data/case-studies/solotech-lime-slurry.md.

Peristaltic For Abrasive Leach Streams

Peristaltic (hose) pumps wet only the hose — no check valves, no seals, no glands in the fluid path — which is the correct architecture for abrasive, solids-bearing leach streams, extending the existing abrasive-slurry-no-centrifugal and crystallizing-slurry-no-valves-seals rules with a second, independent roster vendor confirmation specific to leach-circuit duty. Graco SoloTech is already the roster's confirmed peristaltic line (real lime-slurry case study on file); ProMinent's DULCOFLEX line (captured 2026-09-10, prominent-mining.md) is a second, independent confirmation of the identical hose-only architecture, named by ProMinent specifically on its dedicated mining/heap-leaching and solvent-extraction pages. Specify CSM/Hypalon hose, not generic EPDM, for concentrated acid or caustic leach solution contact.

Confidence: confirmed. Source: data/vendor-sources/prominent-mining.md, data/case-studies/solotech-lime-slurry.md.

Frequently Asked Questions

Does LibertyCES sell lime slurry?

No. LibertyCES supplies the equipment that stores, transfers, meters, and controls fluids like lime slurry (pumps, valves, tanks, piping, instrumentation). It does not supply the fluid itself.

Which engineering rules apply to lime slurry service?

Published rules on this page: Crystallizing Slurry No Valves Seals; Peristaltic For Abrasive Leach Streams. Each links to its full rule page with confidence rating and source.

Is this data a final material approval for lime slurry?

No. It is a screening reference compiled from published vendor data and LibertyCES field rules. Ratings depend on concentration and temperature; confirm against the manufacturer data sheet and your actual duty point, or request a free spec review.
