The pressure difference between the liquid inside the pump and the atmosphere outside the pump exists, and the liquid may leak from the clearance between the shaft and the shell. Therefore, a sealing device, called the shaft seal, is needed. When the pressure in the pump is lower than atmospheric pressure, the shaft seal is used to prevent air from entering the pump; when the pressure in the pump is higher than atmospheric pressure, the shaft seal is used to prevent liquid leakage.Dry vacuum pump manufacturer
The shaft seals commonly used in pumps are generally divided into packing seals, mechanical seal box floating seals and other structural forms.rotary vane vacuum pump
