2. Key operational advantages of Etatron D pumps

Engineered for high-capacity industrial chemical dosing, the Etatron D series delivers consistent volumetric output, mechanical durability, and uninterrupted duty cycle performance. Key advantages include:

Direct electric motor drive mechanism, ensuring high mechanical efficiency and steady-state volumetric accuracy.
NBR/PTFE composite diaphragm design, where the primary PTFE wetted surface shields the underlying elastomeric substrate from aggressive chemical attack.
Hydraulic capacity reaching flow rates up to 535 L/h (50 Hz) or 574 L/h (60 Hz) and working pressures up to 12 bar.
Comprehensive liquid end material selection (PVC, SS316L, and PVDF) to handle acids, bases, coagulants, and organic solvents.
Optimized check valve design: single check valves on SS316L heads and double check valves on PVC heads to prevent backflow and maximize metering precision.
Rugged die-cast aluminum housing coated with anti-corrosion epoxy paint, designed for harsh plant environments.
IP55 enclosure protection and a Class F insulation rating meet strict industrial electrical safety standards.
Supports automated process control via optional external 4-20 mA integration, including electric servomotors (automatic stroke length adjustment) and frequency inverters (frequency/motor speed control) using 4-20 mA signals.
Manufactured under ISO 9001:2015 quality management systems and fully compliant with European Union CE safety directives.
