[Industry News] Electromagnetic Diaphragm Metering Pump

Electromagnetic Diaphragm Metering Pump is a type of Metering Pump, metering pump is a special volumetric pump can be measured fluid being delivered. It is generally composed of the control section, the drive section, the transmission section and the overcurrent section. The difference between the electromagnetic diaphragm metering pump and other metering pumps is mainly the driving section. Electromagnetic diaphragm metering pump is a kind of metering pump which is driven by electromagnet and designed for conveying low pressure and low pressure liquid. It has the advantages of simple structure, easy control, small energy consumption, accurate measurement, convenient adjustment and low price. Its design principle is "simple and convenient", but its disadvantage is that the measurement of small flow (usually 90L / h below), the pipeline pressure is relatively low, which in some ways also limits its industrial application.

The world's first electromagnetic diaphragm metering pump was designed and manufactured by the U.S. company Milton Bar in 1978. Several other foreign brands have since been manufactured or manufactured domestically or domestically, and the quality is still relatively reliable. In 1997, the first truly domestic electromagnetic diaphragm metering pump with independent intellectual property rights started production, thus breaking the market monopoly by foreign brands.

Electromagnetic diaphragm metering pump mainly in the quality of the following aspects:

1, the material selection: As the metering pump delivery is generally corrosive liquids, so for direct and liquid contact with the decay resistant materials have a great Claim. The selection is divided into structural elements and sealing element materials, the principle of selection of material corrosion resistance, processing performance.

2, the pump head structure: the pump head is the over-current part of the fluid being measured, its quality is generally good or bad in terms of structural soundness, sealing, corrosion resistance.
