Jingjin High Pressure Plunger Type Feeding Pump​

Application Areas of Plunger Pump

1. Sludge dewatering: High-pressure plunger pumps are crucial in sewage treatment plants. They efficiently move sludge to dewatering equipment during the sludge dewatering process.
2. Chemical dosing: These pumps dose chemical agents precisely, optimizing the sewage treatment process.
3. Drilling fluid delivery: In oil and gas drilling, high-pressure plunger pumps transport drilling fluid, ensuring smooth drilling operations.
4. High-pressure water injection: In oil fields, they perform high-pressure water injection, boosting the recovery rate of oil wells.
5. Chemical delivery: Suitable for transporting various high-viscosity and corrosive chemicals, high-pressure plunger pumps maintain the continuity and safety of the production process.
6. Reactor feeding: They accurately send raw materials to reactors, ensuring chemical reactions proceed stably.
7. Concentrate delivery: In food and beverage production, these pumps transport high-viscosity concentrates like syrups and juices.
8. Cleaning system: High-pressure plunger pumps power high-pressure cleaning systems, keeping production equipment hygienic and clean.

Jingjin Intelligent Energy-Saving Feed Plunger Pump: Features and Innovative Advantages

1. Wear Resistance: The plunger uses alumina ceramic. After firing, its hardness reaches over HRC8.5, and the surface roughness is 0.4μm. Through fine grinding, it gains excellent wear resistance. When handling materials with sand or solid particles, the plunger doesn’t have shear movement against the material, protecting itself from damage.
2. Strong Self-Absorption Ability: Working in vacuum mode, the plunger can self-prime materials from 4 to 8 meters. The actual suction range may vary depending on the material’s specific gravity.
3. Compact Design: With a built-in plunger cylinder, this pump is shorter than traditional vertical plunger pumps. Its integrated cooling channel prevents circulating water leaks, keeping the work area clean.
4. Energy Efficiency: The pump adopts a large-diameter, double-cylinder hydraulic double pump design. It automatically adjusts pressure according to the filter press’s working conditions, saving energy while maintaining high efficiency.
5. Intelligent Control: Featuring dynamic pressure acquisition, intelligent flow control, and soft piston reversing, the pump reduces vibration and noise, ensuring smooth operation.
6. Simple Operation: Adjusting pressure is easy. Just tighten or loosen the pressure regulating valve. Once set, lock the valve, and no further adjustments are needed.
7. Aesthetic Design: The pump body goes through sandblasting and spray painting. These processes relieve stress, help the anticorrosive paint stick better, and improve the pump’s appearance.
8. Safety and Reliability: Equipped with a safety pressure sensor, temperature overheat protection sensor, and action timeout alarm, the pump operates safely.
9. Top-Brand Electrical Components: The low-voltage appliances inside the cabinet come from Schneider, and the PLC is from Siemens, ensuring high-quality and reliable performance.
10. Versatile Control Options: You can control the pump remotely or locally. For local control, use the piston pump’s control cabinet. For remote control, connect it to the filter press’s control cabinet or upper computer via hard wiring, MODBUS, or Ethernet. This allows you to start the pump and monitor its running state from afar.
11. High Rated Pressure: The feed pressure ranges from 0 to 2.0 MPa (specify if you need 2.0 MPa to 3.5 MPa), and the rated water pressure can reach up to 1.8 MPa.
12. Perfect Match for Filter Press Feeding Process:
    • Initial Feeding Stage: When the filter press chamber is empty, both large and small displacement hydraulic pumps work together to quickly fill it with maximum flow.
    • Pressure Filtration Stage: As the filter press fills and pressure increases, the piston pump adjusts to maintain the right pressure. It switches to the large displacement hydraulic pump and stops the small one.
    • Pressure Holding Filtration Stage: Once the feed pressure reaches the set maximum, the pump switches to the small displacement hydraulic pump, saving energy while keeping the required pressure.
13. Low Maintenance Cost: The main parts that wear out are the valve plate and plunger seal. Replace them every 6 months for ceramic mud applications and every 12 months for municipal sludge applications.
14. Long Service Life: Designed to last at least 15 years.
15. Customized Production: We configure and customize products based on each user’s actual working conditions, making sure they meet specific production needs.
