What Is Metering Pump?

Metering pump is a kind of liquid conveying equipment with high accuracy, good reliability and easy operation, which is widely used in various industrial fields. Metering pump can meet a variety of strict process needs, flow can be stepless adjustment in the range of 0-100%, used to transport liquids (especially corrosive liquids) a special positive displacement pump. Also known as quantitative pump or proportional pump, it is a reciprocating positive displacement pump for accurate measurement, usually requiring stability accuracy of not more than ±1%.

The metering pump is mainly composed of three parts: power drive, fluid transport and regulation control. The working principle is that the drive system drives a CAM to rotate, and changes the stroke length by changing the eccentricity to achieve the adjustment of flow. Under the action of the drive system, the connecting rod mechanism converts the rotating motion into reciprocating motion, driving the plunger or diaphragm movement, thereby inhaling and discharging the liquid. The regulating control system can control the flow and pressure of the metering pump by adjusting the speed of the driving system or changing the eccentricity and other parameters.

Metering pumps have the following features:

• Superior performance: The flow of the metering pump can be adjusted stepless, and has good repeatability and accuracy. At the same time, the metering pump also has stable output pressure and low noise characteristics.

• High safety: The inlet and outlet of the metering pump are usually equipped with safety devices such as safety valves and pressure gauges to prevent problems such as overpressure and overload. In addition, the metering pump also has explosion-proof, shock-proof and other safety measures to ensure safe and reliable operation.

• Wide range of application: metering pump is suitable for conveying a variety of liquid media, such as water, oil, acid, alkali, etc. At the same time, metering pumps are also suitable for a variety of different applications, such as chemical, pharmaceutical, food, petroleum and other fields.

• Easy maintenance: The structure of the metering pump is simple, easy to disassemble and clean. At the same time, the wearing parts of the metering pump are less and the maintenance cost is lower.
