CW型磁力驱动旋涡泵，是小流量高扬程应用的选择，以小流量、高扬程为特征，在许多复杂工况中发挥着其他泵类产品难以替代的作用，是本公司特色的产品，国内小流量泵的空白。

该型泵适用于易燃、易爆、易气化介质的输送，可输送含20%气体的介质，特种结构可应用于汽蚀余量较低的场合。

该型泵具备优良的气液混合功能、液液混合搅拌功能，可以将高分子化合物与难于混合的其他液体均匀混合，解决搅拌机不能胜任的问题。

在石油精炼、精细化工、制药、电力成套设备制造等行业，磁力驱动旋涡泵被广泛应用在液体输送、循环、小流量增压、高压冲洗、高压乳化、高压喷雾等工艺流程中。

CW magnetic driven vortex pump is the ideal choice for low flow and high head applications, with the features of low flow and high head; it can play a role difficult to be replaced by other pump products in many complicated conditions; it is a unique featured product of our company, making up a blank in the low flow pumps in China.

This type of pump is suitable for conveying inflammable and explosive media that can be easily vaporized, and medium containing 20% gas; the special structure can be used in application with fairly low NPSH.

This type of pump has excellent gas-liquid mixing function and liquid-liquid mixing and agitating function, and can homogeneously mix high molecular compounds with other liquid difficult to mix, solving problems that cannot be solved by mixers.

In petroleum refining, fine chemical, pharmaceutical and complete set power equipment manufacturing sectors, magnetic driven vortex pumps are extensively used in process flows such as liquid conveying, circulation, mini-flow boosting, high pressure flushing and emulsifying, and high pressure atomizing.
