The metering pump is also called a quantitative pump or proportional pump. The metering pump is a special positive displacement pump that can meet the requirements of various strict technological processes, has a flow rate that can be adjusted continuously within the range of 0–100% and is used to convey liquids (especially corrosive liquids)
The metering pump is a kind of liquid conveying machinery and its outstanding feature is that it can maintain a constant flow regardless of the discharge pressure. With the metering pump, the functions of conveying, metering and adjustment can be completed simultaneously and as a result, the production process can be simplified. With multiple metering pumps, several kinds of media can be input into a technological process in an accurate proportion and then mixed.
