Polypropylene Centrifugal Pump — ECHO Series
Corrosion-resistant centrifugal pumps with all wetted parts in virgin polypropylene, available in sealed and sealless magnetic drive configurations.
The ECHO Series is a range of corrosion-resistant centrifugal pumps manufactured with polypropylene (PP) wetted parts, designed specifically for handling acids, alkalis, oxidizing agents, and other aggressive chemicals that would rapidly destroy conventional cast iron or stainless steel pumps.
Key features
- All wetted parts — casing, impeller, seal housing — constructed from virgin polypropylene
- Resistant to a wide range of aggressive chemicals including hydrochloric acid, sulphuric acid, caustic soda, sodium hypochlorite, and many common solvents
- Available in standard mechanical seal configuration and magnetic drive (sealless) configuration for zero-leakage chemical handling
- Lightweight construction compared to metallic equivalents — reduces installation load and handling effort
- End-suction, close-coupled or long-coupled configurations available
- Suitable for continuous-duty chemical handling at ambient to moderately elevated temperatures (typically up to 60°C for standard PP grade)
Outcomes
- Dramatically extended pump life when handling chemicals that corrode metals — where a metallic pump might fail within months, an ECHO Series pump can operate for years
- Magnetic drive option provides complete leak elimination — critical for hazardous, toxic, or environmentally sensitive chemicals
- Lower weight reduces structural and pipework support requirements
- No metallic contamination of the pumped fluid — important for certain pharmaceutical and food-industry cleaning chemical applications
Standards & certifications
- ISO 5199 / DIN 24256
