  由于气动隔膜泵具有以上特点，所以在世界上隔膜泵自从诞生以来正逐步侵入其他泵的市场，并占有其中的一部分。如：喷漆、陶瓷业中隔膜泵已占有绝对的主导地位，而在其他的一些行业中，像环保、废水处理、建筑、排污、精细化工中正在扩大它的市场份额，并具有其他泵不可替代的地位。气动隔膜泵的优势在于： 1、由于用空气作动力，所以流量随背压（出口阻力）的变化而自动调整，适合用于中高粘度的流体。而离心泵的工作点是以水为基准设定好的，如果用于粘度稍高的流体，则需要配套减速机或变频调速器，成本就大大的提高了，对于齿轮泵也是同样如此。 2、在易燃易爆的环境中用气动泵可靠且成本低，如燃料、火药、炸药的输送，因为：第一、接地后不可能产生火花；第二、工作中无热量产生，机器不会过热；第三、流体不会过热因为隔膜泵对流体的搅动最小。 3、在工地恶劣的地方，如建筑工地、工矿的废水排放、由于污水中的杂质多且成分复杂，管路易于堵塞，这样对电泵就形成负荷过高的情况，电机发热易损。气动隔膜泵可通过颗粒且流量可调，管道堵塞时自动停止至通畅。 4、另外隔膜泵体积小易于移动，不需要地基，占地面极小，安装简便经济。可作为移动式物料输送泵。 5、在有危害性、腐蚀性的物料处理中，隔膜泵可将物料与外界完全隔开。 6、或是一些试验中保证没有杂质污染原料。 7、可用于输送化学性质比较不稳定的流体，如：感光材料、絮凝液等。这是因为隔膜泵的剪切力低，对材料的物理影响小。

Pneumatic diaphragm pumps for occasions As the pneumatic diaphragm pump with the above characteristics, so since the birth of the diaphragm in the world since the pumps are gradually into other markets, and occupies part of it. Such as: painting, ceramics in the diaphragm has an absolute dominant position, while in some other industries, such as environmental protection, wastewater treatment, construction, sewage, Fine Chemicals is expanding its market share, and can not be replaced with other pump position. The advantage of pneumatic diaphragm pumps: 1, due to the use of air powered, so flow with back pressure (outlet resistance) automatically adjust to changes, suitable for high viscosity fluids. The water pump operating point is set as the base good, if slightly higher for the viscosity of the fluid, you need to complete reducer or frequency converter, the cost will be greatly improved, and the gear pump is the same. 2, in an explosive environment with reliable and low cost air pump, such as fuel, gunpowder, explosives delivery, because: first, grounded not produce sparks; Second, the work is no heat generated, the machine does not overheat; third, because the fluid does not overheat the smallest diaphragm stir the fluid. 3, where the poor site, such as construction sites, industrial and mining wastewater, due to impurities in the water and are complicated, easy to plug the pipe, so that the load is too high for the pump to form the case, the electrical heating vulnerable. Particles and air flow through the diaphragm adjustable, stops automatically when the pipeline to clear blockage. 4, another small easy to move the diaphragm, without foundation, representing the ground is extremely small, easy to install and economical. Materials can be used as portable pumps. 5, in a hazardous, corrosive materials, processing, diaphragm material can be completely separated from the outside world. 6, or the number of tests to ensure that no impurity contamination of raw materials. 7, can be used to transport relatively unstable chemical nature of the fluid, such as: photographic materials, flocculation and solutions. This is because the diaphragm of the shear stress is low, little effect on the physical.
