Slurry Pumps
Naipu slurry pumps are mostly applied in mineral processing systems in non-ferrous and ferrous metals mines. Depending on slurry parameters and heads, a variety of types of slurry pumps are independently researched and developed by Naipu reaches an advanced world level and is the top pump company in China.
1. Unique abrasion-resistant design (with structures, materials),long service life of wetted parts.
2. Wide range of performance, less NPSH, high operational efficiency, and energy-saving.
3. Optional combination of wetted parts of different materials to meet different operating conditions.
4. High cost/performance ratio, easy maintenance and services
5.Suitable for mult-staged installation in series for long distance transfer of mineral slurry.
6. Various mounting forms are available to meet different site installation conditions and customer's requirements.
7. Provide clients with service of pump model selections.
Hydrocyclone
Hydrocyclones are used for improving metal recovery rate, increasing throughput capacity, and creating more economic benefits for the Miner. They are particularly effective in fine particle classification and can also be utilized for other operations such as desliming, desanding, and thickening.
1. Higher capacity.
2. Longer service life of wear parts.
3. Wider application range.
4. Finer separation size.
5. Higher efficiency.
6. Provide clients with designing and model selections
Spares for Vibrating Screens
Features of rubber screen panels and plates Wear occurs badly on the panels due to rubbings between materials and panels during the screening process. Compared with traditional screen plates with different aperture sizes woven by stee| bars, rubber panels and plates produced by Naipu possess merits as of:
1.Light in weight, significantly reducing energy consumption.
2. High damping can reduce noise.
3. Novel structure, offering an easy mounting and removal.
4. Good resillience leading to a higher bounce frequency of materials and an increased screening efficiency.
Spares for Grinding Mills
After long-term R&D, engineering and testing, Naipu has successfully applied rubber liners, composite liners and rubber trommel screens on ball mills, SAG mills and AG mills, and has achieved significant tech breakthrough and innovation.
1. Impact resistance and wear resistance
2. Long service life and high cost-effectiveness.
3. Lower noise than metal liners
4. Lightweight and easy to assemble/disassemble.
Rubber Composite Pipe
Mining hoses and rubber-lined stee| pipes are the two series of products that Naipu manufactures to be used in abrasion and corrosion resistant pipeline systems for transferring mining slurries, tailings and the like.
1. Flexible and impact resistance.
2. High wear resistance, corrosion resistance, and aging resistance.
3. wide temperature (resistance) range from -50°C to 95°C.
4. High static pressure resistance and high tensile strength.
5. Scale inhibition, energy saving, and easy installation.
Spares for Flotation Machines
Considering the flow direction of the pulp in the flotation machine and the main wear conditions, to improve the wear-resistance of the working surfaces of the rotor and stator, the product is designed with a rubber - filling method featuring blades of different thicknesses.
1. High balance precision and operates smoothly.
2. High wear resistance and corrosion resistance.
3. Simple product structure with reasonable streamline design.
4. Lightweight and easy to install, maintain, and repair.
5. Complete product range with high flotation performance.
Ceramic Slurry Pump
Ceramic Slurry Pump – A type of slurry pump where all the wetted parts (flow-passing components) in contact with the transported slurry are made of high-performance engineering ceramic materials, known for their excellent corrosion resistance, wear resistance, and high-temperature tolerance. The ceramic components are encased in a metal shell for protection, with the two bonded together using an adhesive.Key Features: Superior Wear Resistance: 2–3 times more durable than high-chrome metal and wear-resistant rubber, with a Mohs hardness of 9 (second only to diamond). Strong Corrosion Resistance: Resistant to harsh chemical environments. High-Temperature Tolerance: Maintains performance under elevated temperatures. Excellent Cavitation Resistance: Reduces damage from gas bubbles, extending service life.
