Dosing device

1. Overview

Typically consists of one tank, two pumps, and one electric agitator to form a complete system. It can also be configured as two tanks with two pumps, two tanks with multiple pumps, or multiple tanks with multiple pumps according to user requirements. Suitable for the preparation and quantitative dosing of liquid-liquid, solid-liquid, and gas-liquid chemical solutions.

2. Main Features

Fully functional configuration, high safety, and stable performance

Modular design for easy transportation, installation, and maintenance 

Independent electrical control cabinet for convenient installation and debugging (remote/automatic control can also be configured)
