Three ways of sealing slurry pump

Understanding slurry pump first begain from its form of sealing. Here we introduce in detail: slurry pump first is packing seal, one of the most common seal. By inserting shaft seal water, in the form of continuous injection pressure of water in packing, to prevent the leakage of slurry pump body. For not suitable for use to pay the multistage tandem pump impeller shaft sealing, adopt the shaft seal packing. Packing seal structure is simple, convenient maintenance, the price is cheap.
Slurry pump followed by pay impeller seal, through a reverse centrifugal impeller forces, to prevent the leakage of slurry. Import value is not greater than the positive pressure pump outlet pressure value of 10% the first level of single stage or multistage tandem pump pump can be used to pay the impeller shaft seal, without shaft seal pay impeller shaft seal water, not diluted slurry, as well as good sealing effect. So do not allow the dilution in the slurry, may consider such a seal.
Again, mechanical seal, is commonly used in case of sealing requirements higher. In particular, some chemicals, food, not only requires the seal, and most are not allowed to add additional components into the pump body. Drawback is that the high cost, maintenance difficulties, etc.
