MSR H302G Doser

Core Performance & Industrial Application

The MSR Dosiertechnik H302G (H300G series) is a water-powered proportional chemical doser; it needs no electricity and uses line water pressure to drive the dosing motor.

Dose is held constant and strictly proportional to the water volume passing through, independent of pressure/flow fluctuation; suction, metering and mixing happen in one body.

Standard FPM (Viton) seals; internal or external dosing versions; high-viscosity variant available; diaphragm metering piston.

It injects disinfectant/fertilizer/cleaner concentrate into pressurized water lines in irrigation, water treatment and cleaning systems.
