New Type Leakproof Chemical Resistant Chemical Liquid Pumps
Electric Motor Driven
Product Description
The new carbon fiber composite material is our self-developed
high-strength composite material, and has obtained national
invention patent (patent number ZL201310597859.0,
ZL201310343890.1). This material, based on carbon fiber and silicon
carbide, with US imported special cross-linking agent, is made by
chemically reacting at high temperature, and has extreme high
corrosion resistance and wear resistance. The hardness of silicon
carbide is almost as high as that of the diamond, so it has
excellent wear resistance. Carbon fiber can improve the toughness
of material to meet the flexural performance.

Cast Process Advantage
After studied the material properties, our company has found a
special manufacturing process.
Thermal curing casting: The entire manufacturing process of DCS
materials is carried out under vacuum and high temperature. The
combination of coupling agent, tantalum carbide and carbon fiber is
perfect.
Cold-cure casting: Some pumps may have voids, and then repair
materials are essential to repair it. The method is cold-cure
casting, but the material properties are far less than thermal
curing.
Advantage
Comparison to Other Material
A contrast test between carbon fiber composite material and
material 2507: under the same condition, medium: F, CI>800ppm,
containing 12%sulfuric acid and 30%solid content, and its
temperature is 90℃
1) Metal materials have relatively low corrosion resistance and
wear resistance
2) Metallic overcurrent components not only have chemical
corrosion, but also complex electrochemical corrosion.
3) All kinds of colloidal substances and chemical corrosion
products in the medium are attached to the metal overcurrent parts.
Due to the difference of the standard electrode potentials, the
potential imbalance is formed. The solubility of the dissolved
substances changes when the inlet pressure of the pump suddenly
decreases. Then there is concentration differential galvanic cell,
resulting in electrochemical corrosion. When the quality of the
fluid is worse, the phenomenon is more serious.
4) New carbon fiber composite materials contain high-performance
coupling agents with few free electrons on the surface, so there is
no electrochemical corrosion.
5) New carbon fiber composite materials has extremely high hardness
and has higher wear resistance than bidirectional stainless steel
due to SiC
