隔膜泵是一種新型輸送機械，可以輸送各種腐蝕性液體，帶顆粒的液體，高粘度、易揮發、易燃、劇毒的液體。
隔膜泵其有四種材質：塑料、鋁合金、鑄鐵、不銹鋼。
隔膜泵根據不同液體介質分別采用丁晴橡膠、氯丁橡膠、氟橡膠、聚四氟乙烯、聚四六乙烯。以滿足不同用戶的需要。安置在各種特殊場合，用來抽送種常規泵不能抽吸的介質，均取得了滿意的效果。
在噴漆、陶瓷業中隔膜泵已占有的主導地位，而在其他的一些行業中，像環保、廢水處理、建筑、排污、精細化工中正在擴大它的*，并具有其他泵不可替代的地位。氣動隔膜泵的優勢在于：
1、由于用空氣作動力，所以流量隨背壓（出口阻力）的變化而自動調整，適合用于中高粘度的流體。而離心泵的工作點是以水為基準設定好的，如果用于粘度稍高的流體，則需要配套減速機或變頻調速器，成本就大大的提高了，對于齒輪泵也是同樣如此。
2、在易燃易爆的環境中用氣動泵可靠且成本低，如燃料、火藥、*的輸送，因為：*、接地后不可能產生火花；第二、工作中無熱量產生，機器不會過熱；第三、流體不會過熱因為隔膜泵對流體的攪動zui小。
3、在工地惡劣的地方，如建筑工地、 工礦的 廢水排放、由于污水中的雜質多且成分復雜，管路易于堵塞，這樣對電泵就形成負荷過高的情況，電機發熱易損。氣動隔膜泵可通過顆粒且流量可調，管道堵塞時自動停止至通暢。
4、隔膜泵可用于輸送化學性質比較不穩定的流體，如：感光材料、絮凝液等。這是因為隔膜泵的剪切力低，對材料的物理影響小。
5、隔膜泵在有危害性、腐蝕性的物料處理中，隔膜泵可將物料與外界*隔開。
6、隔膜泵或是一些試驗中保證沒有雜質污染原料。
另外，隔膜泵體積小易于移動，不需要地基，占地面極小，安裝簡便經濟。可作為移動式物料輸送泵。
Diaphragm is a new type of conveyor can transport all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous liquid.
Diaphragm pump has four of its material: plastic, aluminum, cast iron, stainless steel.
Diaphragm under different liquids were used NBR, chloroprene rubber, fluorine rubber, PTFE, poly ethylene 46. To meet the needs of different users. Placed in a variety of special occasions, for pumping of conventional pump suction should not the media, both with satisfactory results.
In painting, ceramics in the diaphragm has a dominant position absolute, while in some other industries, such as environmental protection, wastewater treatment, construction, sewage, Fine Chemical is expanding its market share, and have the other pump can not be replaced status. Pneumatic diaphragm pump has the advantage of being:
1, because of air to make power, so with the back-pressure flow （exports resistance） automatically adjust to changes, suitable for middle-and high-viscosity fluid. The point is that is the job of centrifugal water benchmarking best, if used for higher viscosity fluids, the necessary supporting reducer or VVVF costs are greatly increased, the gear pump is the same.
2, in the explosive environment pneumatic pump with reliable and low cost, such as fuel, gunpowder, explosives, transmission, because: first, after the grounding could not produce sparks; Secondly, the job is no heat generated, the machine not overheating; Third, the fluid does not overheat because of the fluid stirred diaphragm minimum.
3, at the site of the worst places, such as construction sites, industrial wastewater discharge, because of the sewage of many impurities and complicated, easy to plug the pipe, so that the load on the pump is too high to form the situation, the electrical heating vulnerability. Pneumatic diaphragm pumps and flow through the particles adjustable, pipe plug to open automatically when to stop.
4, diaphragm pumps can be used to transport the chemical nature Unstable fluid, such as: photographic materials, such as flocculation liquid. This is because the diaphragm shear stress is low, the impact of small physical Materials.
5, there is harm in the diaphragm, corrosive materials processing, the diaphragm can be compley separated from the material with the outside world.
6, diaphragm, or a number of tests to ensure that no contamination of raw materials.
In addition, the diaphragm are small easy to move, Do not need foundation, or the ground is extremely small, easy to install the economy. Materials can be used as portable pump.
