Natural rubber: has excellent flex resistance, good abrasion resistance, cold resistance and insulation, and high tear strength. It has poor aging resistance, poor weather resistance, oil resistance and solvent resistance. The rubber pump made of natural rubber compound has a suitable working temperature below 78℃. It is suitable for conveying a variety of abrasive slurries and weak acid and weak alkali solutions, but not suitable for conveying strong acid, oil, aliphatic and aromatic solutions.
Nitrile rubber: It is currently the most widely used oil-resistant rubber variety. It has a series of superior properties. Its wear resistance is 30-45% higher than natural rubber, and its high temperature resistance is better than natural rubber and styrene-butadiene rubber. But nitrile rubber has poor weather resistance. The rubber pump made of nitrile rubber compound has a maximum operating temperature of 95℃. The rubber pump of this type of rubber is resistant to various animal and vegetable oils, mineral oils and glycols.
Butyl rubber: rubber-lined pump parts made of butyl rubber compound, suitable for acid mud work. The maximum operating temperature is 100℃, which can withstand strong acids and alkalis (such as hydrochloric acid, sodium hydroxide), but high concentrations of oxidizing strong acids (such as concentrated sulfuric acid, concentrated nitric acid) will degrade butyl rubber.
Rubber O-rings are commonly used in pumps. Because of its very simple shape, it is easy to manufacture and low in cost. No matter how large the overall size of the O-ring, its cross-sectional size is very small (only a few millimeters), so it is light in weight, consumes less materials, is simple to use, and is easy to install and disassemble , The more prominent advantage is that the O-ring has a good sealing ability and a wide range of applications.
The working Self-priming Surface Pumps Manufacturers of static seal can reach more than 100MPa, and the dynamic seal can reach 30Mpa. The applicable temperature is -60～200℃, which can meet the requirements of various media. Therefore, it is more and more widely used in pump design.
The O-ring seal is installed between the groove and the sealed surface with a certain amount of compression, and the resulting rebound force gives the sealed smooth surface and the bottom of the groove an initial compressive stress. So as to play a sealing role.
When the pressure of the sealed liquid increases, the deformation of the O-ring also increases, so that the pressure transmitted to the sealing surface also increases, and the sealing effect increases. This is the reason why O-rings have good sealing capabilities.
