HYMaxFlow 8921 Pump

In oilfield operations, industrial Electrodeionization (EDI) pumps are deployed inside heavy-duty, skid-mounted water treatment systems. Their primary function is providing continuous polishing of feedwater for high-pressure steam generation, refinery utilities, and gas turbine injection without requiring chemical storage. Used in desalting units, hydrocrackers, and catalyst preparation loops where residual ions (such as sodium and chloride) cause stress corrosion cracking or catalyst poisoning.

Main Features

✔ Modular & Scalable Stack Design
✔ Continuous Chemical-Free Purification
✔ Ultra-Pure Water Output
✔ Oil & Hydrocarbon Limits
✔ Heavy-Duty Construction
✔ Automated & Low Maintenance
