Metering pump

The metering pump is mainly composed of three parts: power drive, fluid delivery, and regulation control. The power drive device drives the fluid delivery diaphragm to achieve reciprocating motion through a mechanical linkage system: the diaphragm (piston) will be sucked in by the delivered fluid in the first half of the stroke and discharged from the pump head in the second half of the stroke; Therefore, changing the reciprocating frequency of the stroke or the stroke length of each reciprocating motion can achieve the goal of adjusting the fluid delivery volume. The precise machining accuracy ensures the precise measurement of the conveyed medium by pumping out each time. The metering pump products produced by Shanghai Meiyanyi Pump Valve can be roughly divided into two types: plunger metering pumps and diaphragm metering pumps, based on their different power drive and fluid delivery methods. A metering pump, also known as a quantitative pump or a proportional pump, is a special type of volumetric pump mainly used to meet various strict process requirements. Its main feature is the ability to achieve stepless adjustment of flow rate within the range of 0-100%, suitable for transporting various liquids, especially corrosive liquids. The stability and accuracy of a metering pump are usually required to not exceed ± 1%, which makes it particularly important in applications that require precise metering. Shanghai Meiyanyi Pump Valve is one of the main manufacturers of metering pumps, which are mainly suitable for the petroleum and chemical industries. Metering pumps are mainly used in these industries to extract or transport various media, such as crude oil, acid-base solutions, solvents, etc., as well as to circulate and filter liquids. In the food industry, metering pumps are used to accurately measure various liquid foods, such as beverages, milk, juice, etc; In the pharmaceutical industry, it is used for precise measurement and dispensing of drugs to ensure the accuracy of dosage and stability of the medication. The following pictures and drawings of various specifications and models of metering pumps are provided for your reference in selection.
