EMG Models

MOTOR DRIVEN DOSING PUMP

The EMG model is from the Eignal Series Dosing Pump family. This is a smart, digital intelligence model designed for this new digital world. This is a volumetric, mechanically operated reciprocating metering pump. Widely used in petroleum, chemical, food, pharmaceutical, paper, light industry, agriculture, water plant and other industrial and technological sectors, in the process of dealing with all kinds of media measurement and dosing applications. According to different media, different selection of materials is available, including PVC, SS304, SS316, PTFE and others.
EMG series metering pump can transport temperature -15 ℃ ~ 60 ℃, viscosity 0.3 ~ 1000cps corrosive or non-corrosive liquid which does not contain solid particles. Pump rated flow range is 15 ~ 130 l / h, with corresponding maximum output pressure of 10 ~ 4bar. The flow rate of the pump can be adjusted by the hand wheel from 0% to 100%, regardless of whether the pump is running or not. In the range of 30% ~ 100% flow rate, the steady-state accuracy is ± 1%. It is a simple structure, small energy consumption, accurate measurement practical metering pump. Different models can be configured according to the requirements of 220V, 380V or other voltage motor.
