Pneumatic diaphragm pump selection considerations

Pneumatic diaphragm pump is a compressed air, all kinds of corrosive, high viscosity, volatile, flammable, highly toxic liquids are exhausted to the new pumping machinery. Although the current environmental protection pump industry is being developed, but many businesses are still how to choose the right type of diaphragm pump headache. Xiaobian today for everyone inventory pneumatic diaphragm pump selection considerations, to help buyers buy better. Pneumatic diaphragm pump selection precautions Pneumatic diaphragm pump selection should focus on the following aspects: 1, the pneumatic diaphragm pump fluid temperature of how many degrees, there is no more than 80 degrees, the temperature of the performance of the pneumatic diaphragm pump great impact , As the diaphragm material pneumatic diaphragm pump made of rubber or PTFE material, such as the temperature is too high, the diaphragm will become soft, it will lead to pneumatic diaphragm pump can not absorb liquid and liquid. 2, pneumatic diaphragm pump used condition adjustment. Users need the flow should be based on user-supplied liquid concentration and gravity to choose the right model, pneumatic diaphragm pump usually marked flow head is the maximum diaphragm pump, the actual parameters should check the performance of pneumatic diaphragm pump curve is accurate . Pneumatic diaphragm pump flow head is also with the gas supply and supply pressure changes the size of the pneumatic diaphragm pump maximum supply pressure can not exceed 0.8mpa, so the pneumatic dual diaphragm pump lift only up to 80 meters, here Note that a value of 80 meters is obtained from the water test. If you transport the medium, the other mediums that are heavier than water will decrease in head lift. 3, the pump material and diaphragm and seal selection. Diaphragm damage caused by failure accounted for a high proportion of pneumatic diaphragm pump failure, in some cases can reach 30% to 40%. Therefore, the choice of diaphragm material pneumatic diaphragm pump is crucial. Selection of the media must be delivered to the name of the diaphragm pump plant to choose the appropriate material diaphragm, due to the large variety of chemical liquids, corrosive various liquids are also different, the precise characteristics of the required parameters, especially corrosive , Concentration, volatility, vapor pressure, viscosity, density, etc. These properties are closely related to material selection, not only the metal material, but also the plastic material and the medium interaction. Pneumatic diaphragm pump selection noted that the above points before you can choose the right pneumatic diaphragm pump products. Industry Internet (Xiamen) Technology Co., Ltd.
