EHN Series Dosing Pump Description

Hennvi’s EHN Series Dosing Pump is a fluid delivery system specifically designed for high-precision liquid dosing. As a compact, space-saving industrial dosing pump, this unit features a versatile modular design and offers a variety of pump head materials—including PVC, GFRPP, PVDF, and SUS—allowing for easy installation in confined spaces. All wetted parts are constructed from top-tier corrosion-resistant materials such as HC alloy, ceramic, fluororubber, and PTFE, ensuring optimal compatibility with corrosive fluids.

This diaphragm dosing pump features an exceptional stroke frequency of up to 360 strokes per minute and is equipped with a manual adjustment knob that allows for real-time flow rate adjustment during operation. It also boasts excellent self-priming capability, providing a self-priming head of up to 1.5 meters, making the initial priming process easy and effortless.

As a top-of-the-line chemical dosing pump, it is the ideal choice for automated chemical dosing. It delivers outstanding performance in wastewater treatment chemical dosing, swimming pool water treatment, automatic replenishment of electroplating chemicals, and laboratory fluid dispensing.
