Requirements for dielectric properties

    According to different media that the liquid pump deliveries, the requirements of the liquid pump is not the same. They are summarized as follows:
If the liquid pump deliveries liquid pump that it deliveries flammable, explosive, toxic or expensive media. It requires reliable seal or to use no leakage of the pump, such as shield pumps, magnetic drive pumps, diaphragm pumps and so on.
    If the liquid pump transports corrosive medium, the parts of flow are required to use corrosion-resistant materials.
    If the liquid pump deliveries solid granules medium, a components of the flow are made of wear-resistant material, it is necessary that the seal should be the clean liquid flushing.
