Question: Do all pumps have mechanical seal?
Not all pumps have mechanical seals. Some pumps use other types of seals, such as packing seals or lip seals, depending on the design of the pump and the nature of the fluid being handled.
Mechanical seals are commonly used in pumps that handle fluids that are hazardous, corrosive, or difficult to seal, as they provide a reliable and effective sealing solution. Pumps used in the chemical, petrochemical, pharmaceutical, and food processing industries are often equipped with mechanical seals due to the high demands placed on them.
However, in some applications, other types of seals may be more suitable or cost-effective. For example, packing seals are often used in pumps that handle non-hazardous fluids, or in applications where the sealing requirements are less demanding.
Ultimately, the type of seal used in a pump will depend on a variety of factors, including the type of fluid being handled, the operating conditions, and the requirements of the application.
