Horizontal Carbon Fiber Acid Transfer Pumps High Performance Wear
Resistance
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.

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
Pump Design Feature
- Single-stage single suction horizontal centrifugal pump
- Closed impeller, twisted blades, all heavy-duty design, ensure the
good hydraulic performance
- The single-end mechanical seal adopts an external structure to
ensure that all parts in contact with the liquid are non-metallic
materials.
- Special impeller positioning method can ensure the safety of the
impeller, and It is very easy to assemble and disassemble
- Flow passage components are all made of new carbon fiber composite
materials
- The bearing box structure and the movable rotor component ensure
the pump always runs at the best condition
