Peristaltic For Abrasive Leach Streams

Direct answer: 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

This is a general engineering rule derived from real field/case-study evidence, not a substitute for a project-specific specification review — confirm against your exact process conditions before ordering equipment.

Applies when	peristaltic pump leach, hose pump leach solution, abrasive leach stream, dulcoflex, leach solution metering pump, solids-bearing leach slurry pump
Avoid	diaphragm metering pump with check valves in abrasive leach service, centrifugal pump in leach slurry (Pump)
Recommend instead	Graco (SoloTech) or ProMinent Fluid Controls (DULCOFLEX DFBr/DFBu/DFCu/DFDu) peristaltic / hose pump (Pump)
