The advantages of metering pumps produced by metering pump manufacturers are high precision, good stability, easy operation, and convenient maintenance. It can accurately measure various liquids, such as chemicals, oils, food, etc., and has strong applicability and flexibility. At the same time, the pressure range of the metering pump is wide, which can meet different process requirements and ensure the normal operation of the fluid.

In the food industry, metering pumps are commonly used to transport various liquid foods such as juices, beverages, sauces, etc. A metering pump can maintain the quality and taste of food, ensuring its hygiene and safety. In the petroleum industry, metering pumps are widely used to transport crude oil, petroleum products, and chemical products such as petroleum, kerosene, lubricants, etc. Metering pumps can accurately control the flow rate and pressure of fluids, ensuring stable and efficient production processes of petroleum products.

What are the types and characteristics of metering pumps worth understanding?

1. Positive displacement pump: A positive displacement pump is a metering pump that achieves flow control by changing the pump chamber volume. Its characteristics are simple structure, easy maintenance, stable flow rate, and small pressure fluctuations. Common volumetric pumps include plunger pumps, gear pumps, etc.

2. Screw pump: A screw pump is a metering pump that uses the rotational motion of a screw to drive liquid transportation. Its characteristics are large conveying flow rate, stable pressure, and suitable for conveying high viscosity liquids. Screw pumps are usually divided into two types: single screw pumps and twin-screw pumps.

3. Diaphragm pump: A diaphragm pump is a metering pump that delivers liquids through the movement of a diaphragm. Its characteristics are simple structure, good sealing, and suitable for transporting corrosive liquids. Diaphragm pumps are usually divided into two types: pneumatic diaphragm pumps and electric diaphragm pumps.

4. Gear pump: A gear pump is a metering pump that achieves flow control through gear transmission. Its characteristics are smooth operation, low noise, and suitable for transporting high viscosity liquids. Gear pumps are usually divided into two types: internal gear pumps and external gear pumps.

5. Centrifugal pump: A centrifugal pump is a metering pump that pushes liquid out through centrifugal force. Its characteristics are high flow rate, high pressure, and suitable for situations where liquid transportation distances are long. Centrifugal pumps are usually divided into single-stage centrifugal pumps and multi-stage centrifugal pumps.

A metering pump is a device used for accurately measuring fluids, widely used in industries such as chemical, petroleum, pharmaceutical, and food. The working principle of a metering pump is to deliver accurately measured fluid into the system through structures such as plungers and gears, ensuring accurate fluid delivery and control. The high precision and good stability of metering pumps make them an essential equipment in many industries.

The working principle of a metering pump is to press fluid into the pump chamber through structures such as plungers and diaphragms, and then discharge the fluid through changes in pressure or volume. The metering pump can adjust its working speed and pressure according to demand to adapt to different working conditions. In the field of chemical engineering, metering pumps are commonly used to transport various chemicals, solutions, and suspensions, such as acid-base solutions, chlorides, hydrogen chloride, suspended solids, etc.
