What are the advantages of centrifugal pump and pneumatic diaphragm pump?1 pneumatic diaphragm pump by using air as the power, so the traffic along with the change of back pressure (outlet resistance) automatically adjust, suitable for high viscosity of the fluid and the centrifugal pump is a working point of water as a benchmark to set a good, if slightly higher viscosity fluid, you need to form a complete set of reducer or the frequency conversion governor, cost is greatly improved, the gear pump is the same is true of 2 pneumatic diaphragm pump can be used to transport the chemical nature is unstable fluid, such as: photographic materials such as flocculation liquid pneumatic pump of the shear stress is low, this is because the small 3 physical impact on the materialIn site bad places, such as the construction site of industrial and mining waste water emission due to the impurity in the sewage is much and complicated composition, line easy to jam, and so on high pumps forming load, motor heating vulnerability of pneumatic diaphragm pump can be through the particles and the flow rate is adjustable, blockage can automatically stop to open 4 in damaging corrosive materials processing, can be completely separated from the material and the outside world, or some tests to ensure no impurity pollution materials 5 in inflammable and explosive environment pneumatic diaphragm pump with reliable and low cost, such as the fuel of the explosive powder conveying, because: 1No spark is possible after grounding;Second, no heat generated in the work, the machine will not overheat;The third fluid will not overheat because the pneumatic diaphragm pump on the fluid agitation minimum 6 in addition the pneumatic diaphragm pump volume is small and easy to move, do not need the foundation, occupy the ground is very small, simple and economical installation can be used as a mobile material transport pump.
