Peruvian customer purchases Teflon centrifugal pumps.

RISTER PUMPS PTFE‑lined centrifugal pumps are now on shipment for calcium chloride solution service.
Calcium chloride brine is highly corrosive with strong chloride‑induced pitting risk, which easily attacks regular stainless‑steel pump parts. Our full PTFE‑wetted construction delivers reliable real‑world performance:
- Outstanding chemical inertness against calcium chloride across different concentrations and working temperatures, no pitting or stress‑corrosion cracking as seen on metal pumps.
- Smooth non‑stick PTFE surface cuts salt crystal buildup, reduces fouling and frequency of manual cleaning.
- Complete isolation between aggressive brine and outer metal housing, prevents medium contamination and extends pump service life under continuous running.
- Robust steel outer casing guarantees mechanical strength for piping loads, while PTFE lining takes all chemical attack.
Built for long‑term stable transfer of calcium chloride brine in chemical processing, wastewater treatment and brine handling sites. Units are packed and ready for delivery to site.
