Chemical pump oil seal is a self -tight lip -like seal. Its structure is simple, small in size, low in cost, convenient maintenance, and small hindrance to prevent the medium leakage, but also prevent external dust and other harmful substances, and It has a certain compensation capable of wear, but it is not resistant to high pressure, so it is generally used on a chemical pump on low -pressure occasions.

The chemical pump relies on the principle of centrifugal to extract liquid materials. The chemical pump made of special materials is suitable for bottle, barrel, cylinder, pool, or other container to extract corrosive liquids. Due to the existence of risks such as corrosion, volatilization, and explosion, the sealing performance requirements of the chemical pumps are much higher than other types of pumps.

The chemical pump oil should be installed on the manufacturing accuracy of H8 ~ H9, the surface roughness of 1.6 to 0.8 μm and the surface hardening treatment. The sealing medium should not contain solid particles and impurities, otherwise it will cause rapid wear of oil seal and axis to make the seal failure.

In selecting this sealing method, it is necessary to fully consider the performance and requirements of the material transported by the chemical pump to avoid unnecessary leakage and prevent accidents.
