General gear pump and multistage pump in the process of use will appear oil leakage and oil rejection, our plant designed bellows mechanical seal effectively prevent the occurrence of the above phenomenon, and has high pressure resistance, long service life, easy installation and other advantages.
Bellows are widely used in instruments and meters, and their main purpose is to be used as the measuring element of pressure measuring instrument to convert pressure into displacement or force. The bellows have thinner wall and higher sensitivity, and the measuring range is from tens of pa to tens of mpa. Alternatively, the bellows may be used as a sealed isolation element to separate the two media or to prevent harmful fluids from entering the measured portion of the device.
