Installation process：

1.Clean the installation area, remove the original seals, and clean the surface of the installation area and related components.
2.Ensure that the surfaces of components such as the base, static sealing ring, dynamic sealing ring, and packing box are clean, flat, undamaged, and rust free.
3.Select the corresponding mechanical seal based on the model and medium of the pump. If unsure about the selection, it is necessary to consult professional technicians.
4.Assemble the mechanical seal in order according to the requirements in the assembly drawing.
5.Apply a clean layer of lubricating oil on the dynamic and static mirror surfaces; Apply lubricating oil to the guide bearing seat, then gently position the static ring and install it into the guide bearing seat; Apply lubricating oil to the pump shaft and gently install the dynamic ring part of the mechanical seal onto the pump shaft.
6.Keep clean and do not allow tools to strike the sealing components to prevent damage and destruction.
7.During installation, the surfaces of the dynamic and static rings should be coated with a layer of clean engine oil and turbine oil. Before installing the auxiliary sealing ring, it is also necessary to apply a layer of clean engine oil or turbine oil to ensure smooth installation

Background:

The difference between balanced and unbalanced mechanical seal needs to be comprehensively judged based on specific working conditions (such as medium pressure, lubricity, etc.). The applicable scenarios and performance characteristics of the two differ significantly, as follows:
1、 Durability comparison and conclusion
Low pressure condition (≤ 0.7MPa): Non balanced type is more durable
The non-equilibrium structure is simple, with no additional steps or complex components, low failure rate, and moderate end face pressure under low pressure, resulting in uniform wear.
For example, low-pressure equipment such as triple effect evaporator condensate water pump and cooling tower circulation pump can operate stably and have low maintenance costs in non-equilibrium type.
High pressure/harsh working conditions (>0.7MPa or poorly lubricated media): Balanced type is more durable
The balanced type adopts a pressure unloading design to avoid a sharp increase in end face pressure with the increase of medium pressure, reduce wear and heat generation, and is suitable for high-pressure, low viscosity (such as liquefied gas) or corrosive media.
For example: liquefied gas pump, high-pressure reactor discharge pump, balanced type can withstand higher pressure and have a longer service life.
Key points to note
Limitations of non-equilibrium type: If used at pressures exceeding 0.7 MPa, it may cause seal leakage and shortened lifespan due to excessive end face pressure.
The advantage boundary of balanced type: Even under high pressure, if the lubricity of the medium is extremely poor (such as liquefied gas), balanced type still needs to further improve durability through material optimization (such as hard alloy friction pairs).

2、 Summary
Priority should be given to non-equilibrium types: clean liquids with medium pressure ≤ 0.7MPa and good lubricity (such as water and engine oil).
Balanced type must be selected: medium pressure>0.7MPa, poor lubricity (such as liquefied gas), corrosive or high viscosity liquid.
The essence of durability: The two types of"durability"depend on whether they match the working conditions - unbalanced type is more reliable under low pressure due to its simple structure, and balanced type is more durable under high pressure due to pressure control. It is meaningless to talk about"absolute durability"without considering the working conditions, and the selection should be based on specific pressure and medium characteristics.If you want to view other products,pls see this website & www.aefluidtec.com/
